Hi Everybody,

Just wanted to let the automatic RX8 owners know that the Greddy kit fits on the car. The e-manage would not work however, so I used my other e-manage that I had been experimenting with. I used the harness that came with the kit. Jumpers 5 and 6 inside the emanage were turned off. I am using just the additional injector map to control the 4 injectors. My initial tuning has the air/fuel ratio in the 11 range. I would like to gradually lean it out to about 11.5. The only problem is that the injectors are running at about 95%+ duty cycle. This is too high, so I am going to replace the secondary injectors with 550 cc ones from RC Engineering.
For a blow off valve, I used one from a 1993 RX7. It is plumbed between the pipe near the throttle body and the air inlet pipe coming from the air filter.
I had done some 0 - 60 mph tests before the turbo install. I averaged 8.8 seconds. After the turbo install, I averaged 6.4 seconds. These times were done by pre-loading the torque convertor by standing on the brake and gas at the same time. I plan to dyno the car after the larger injectors are installed.

Later,

Rick

FYI, apex8 is Rick from Rick's Rotary. They're the guys in Pleasanton who work on RX-7s, recommended by Bern and installed my ACT flywheel. Rick has lots of experience with eManage tuning in general. The turbo'd auto is his personal car so you can be sure he's doing a meticulous job. This is Rick's first post although he's been lurking for a while.

cool. it would have been nice to hear that from him though.

There is a light at the end of the tunnel. Thanks Rick.
Also could you take a pic of the BOV near the TB?

Rick congratulations man - thatsgreat news for all of us auto owners. A 6.4 0-60 ispretty decent considering what our automatics run stock (mines around 8.1) - so atleast now you have some respectable straight line performance. I wonder how powerful it feels in the mid range. Also let us knowhow the tranny holds up

Clearly if/when I go this route itwill be w/SSRs kit.

Hmmm--very interesting, 6.4 consistent seconds to 60 is what the auto RX8 should have been doing in the first place--but this is the route I may go once my warranty is up. Keep us posted--and good work.

I new the auto would be fine. How does it shift? Any slippage at all?

Apex8, maybe you can give us a run down on any and all mods you have on your RX8. Alot of us would be interested what youv'e put together, like intake and exhaust to go with the turbo. Thanks!

cool. it would have been nice to hear that from him though.I don't know at what point it becomes "illegal" advertising, so I thought I'd put a plug in for him. Just from his post alone you wouldn't know he's a professional mechanic with years of experience working on rotaries--although the information content is a definite clue. ;)

Wait actuallyI have a question for whoever can answer this. How is it that Ricks automatic Rx8 improved over 2 seconds in its 0-60 time (went from an 8.8 to 6.4) w/the GReddy turbo kit while philodoxs manual Rx8 made a much less impressive improvement (went from 5.9 seconds to somewhere around 5.0 - 5.2 seconds)?

Why would the smaller engine make a larger gain than the bigger one w/the same exact kit?

Adding horsepower to a lower powered car will make more of adifference then adding horsepower to a higher power car. Example: adding 30hp to a 200hp engine will make a bigger difference in 1/4mile times compared to adding 30hp to a 500hp engine. Well, I think that is why there is a difference. I could be completely wrong. :o

Why would the smaller engine make a larger gain than the bigger one w/the same exact kit?

Well--we would need to compare the powerbands of the two cars--but in essence I believe that the auto has more consistent performance than the manual--remember the 5.9s in the 6spd is hard to repeat consistantly. Also I think that some folks commented that due to the 4-port config they respond better to boosting--perhaps someone else can offer a more technical response.

Two points to consider:
1. The stock auto has slightly more torque than the manual.
2. Diminishing returns means the next incremental increase takes more effort.

I guess itreally doesnt matter in a sense b/c even though he is technically making larger gains than the manual Rx8s are w/the same exact kit - its still not performing quite as fast as the stock manual Rx8. Wouldnt it be more beneficial to have a kit specifically designed for the automatics 4port configuration rather than using a hand me down from the manual or is that irrelevant?

Which components would be different for an automatic vs. manual? Except for the larger fuel injectors kit components would be the same.

air flow wise the 4 port and 6 port engines are pretty similar up to about 7000 rpm i'd be willing to bet. When the tertiary ports open on the 6 port, that's where you'd see a difference. Therefore you should be able to get away with using the same setup.

I'd really like to see a stock dyno on a 4 port. I don't think they suffer as much from the factory tune as the 6 ports. The 6 ports are losing 20hp to that (based on a few peoples statments in other threads, don't want to get this thread hijacked with another hp discussion), I wonder if the 4 port loses anything at all. I doubt they had to cut back on power like on the 6 port for cat longevity (since they use the same cat). But what do I know :D .

Being part of the minority on this forum sure does sucks (this thread is barely getting any attention).

Anyway Im pretty sure our automatics fall somewhere in the 130 - 150 whp range.

Still not sure if buying a turbo kit for our automatics is viable though b/c if Gordons rumor ends up being true and Mazda is upgrading the automatic Rx8s to the high power engine for the 2006 model year - then youll probably have stock 2006 automatic Rx8s doing 60 in low 6s that you can trade for + warranty + everythings brandnew.

Regardless I hope Rick manages to squeeze some more power out of GReddys kit. What hes already accomplished is amazing (a 2 second improvement for less than 5grand?) but itd really be great if he could get his automatic Rx8 to match the performance of the stock manual Rx8s w/this kit. Hes almost there anyway.

This is true--I probably would trade mine in on the hi-power RX8 if this is true as well--especially if the SMG comes to fruition.

JeRKy 8 Owner Being part of the minority on this forum sure does sucks (this thread is barely getting any attention).


I've been following this thread since the onset and am sure that there are many others. I don't want to sound as stupid as I am about what your doing so I try and stay in the shadows. All I know is I want to go faster. PLEASE KEEP THE COURSE. I will send a little encouragement from time to time

:P cant wait to get more power out of my AT RX8 :D

Any new developments on this end?

The European 192 hp version has got a 5-spd manual box.
Mazda claims 7,2 sec for 0-62 mph(0-100 km/h).The only test I've seen is 7,7.
The LP hits the rpm-restrictor in 2nd gear at 104 km/h.(64,6mph)
The 5-spd man is therefore obviously faster than the 197 hp 4AT..

The Euro 231 hp 6-spd got a claimed 6,4,but best I've seen is 6,9...

Its been nearly 2 weeks since Rick (apex8) last posted anythingabout his turbo charged automatic Rx8. PUR NRG couldyou call him andask him to post an update for us?

Three weeks andstill nothing. Must have fuckedup his car or something..

lol true..where are you rick?

Rickkkkkkkkkkkkkkkkk?

Ok, I've got a few more things done to the car. Didn't mean to take so long. Finally got the larger secondary injectors installed. Went with 650cc ones from RC Engineering. The primary injectors are stock. I enclosed a picture comparing the stock injector to the RC injector. Just finished most of the fuel re-mapping. Duty cycles are down to about 85% now. Still need to fine tune it on a dyno.
The drivability is almost as smooth as stock. I had my wife use the car to run some errrands, and when she got back she said it felt like a turbo RX7 now. Much more responsive.
I was a bit concerned about how well the transmission will hold up when shifting at full power. A friend at a transmission shop told me about a device that will allow you to raise the line pressure in the transmission, thereby applying more force to the clutches. The picture of it shows that you can adjust it from in the car for best performance. The unit is made for a 1993 RX7 transmission, but the RX8 one is from the same family. It goes on next.
I have enclosed some other pictures including the 1993 RX7 blow off valve, my nav display showing boost and water temp gauges (HKS CAMP), my canscan from the laptop on the car display, as well as one from the e-manage software showing injector duty cycles. It is a bit hard to read the smaller text, but it is easier than looking down at a laptop screen when driving.
After the dyno testing and transmission pressure device are installed I will let you know how it turns out. But for now, with the turbo install it makes driving the car way more fun.
Rick

couln't get the last picture in.

Oh Hell Yea !
Sounds like its time to buy a Greddy kit before the price jumps up to much.
With the raised pressure in the trans, will the "clutch rings" wear faster?
Is there a downside to the higher pressure?

From what the transmission shop owner tells me, there is less wear with the increased pressure because the clutch bands won't be as likely to slip. The pressure increase is applied only at full throttle. The downside would be that if you have the pressure too high, you will get whiplash when the transmission shifts. You want the shift to be firmer, but not harsh. I will know more about this when I get the unit installed on my car.
Rick

Very nice.

Very impressive.

I wonder how much power he's gotten up to?

RWHP?

Rick how many psi are you planning on taking GReddys kit up to w/your automatic?

For now I don't plan to take the boost over 7 psi. I may change my mind after I dyno the car. I hope to get it on a dyno within a couple of weeks. I don't think that there is enough fuel flow capacity with the injectors I am running right now. (stock primarys and 650cc secondaries).

Rick basedon how your car is responding to the GReddy kit - do youthink our automatics could handle the more powerful SSR turbo kit? Or would installing that kit require us to replace too many parts (for stability sake)?

Apex8, where did you get the pressure riser unit? Online dealer?
Thanks.

I just wanna know how much total is this whole thing costing??

Pimp in da Rx8, how do you get the button tufted diamond shape back window thing to work on the 8?? :confused:

Please tell me you also installed an auxilary transmission cooler...I'm assuming you did since their only about 50 bucks (for a stacked plate) and make a huge difference in longevity, protection, and performance.

In answer to some questions -

JeRKy8 - don't know yet about reliability - this is the first automatic Mazda I've hopped up. Time will tell. Heat is probably the worst enemy.

Crossbow - I plan later this week to add an additional cooler on the right side of the front end per the transmission shops reccomendation.

bxb40 - the pressure riser came from www.superior-transmission.com.
They carry lots of interesting transmission parts.

Will update later after more testing.

Rick

Ok i have this engine but not on a Auto box (not avalible in Europe) so it should be alot easier to fit right?

apex,

Awesome. It makes a really big difference. Have you taken any temp readings? Both the 6i ATX and the 6s ATX's (jatco not the new 6spd) have overheating issues on stock setups. I'd imagine the 8's 4spd probably is overheating a bit from the factory as well. You'll know instantly if your shifts improve with the cooler. (If it was overheating or not).

If they do, please start a thread for your fellow members, so as to prevent premature transmission failure around 60-80,000 miles. Tranny coolers are so cheap and easy to install, but are often overlooked as a modification. Most people don't realize how big of a difference they can make in the longevity of a transmission. In most cases they can more then double the lifespan...all for less then 50 bucks.

Considering the cost of a new ATX + labor, an Aux ATX cooler (stacked plate like B&M or Hayden with pressure drop protection) should always be one of the first modifications to an ATX equipped vehicle...regardless of power. As long as you run it inline with the stock radiator cooler, it won't effect the warranty in any way.

any new developments on this front?

what about the 2 extra air ports that the 6-speed has. wouldnt that be a factor in all of this. When i spoke to greddy, they said that they would think about working on a kit for the auto but they only were only going to release the kit for the 6-speed for now.

The thing is, if I remember correctly, they've already designed a system for the auto. They just did it for Re-Amemiya.

i think the one in japan trust(greedy) have the kit for auto... i haven't install that yet.. but i will found out after 20,000km after everthing run smooth...
but i heard that u only max boosting is 9psi

Its been almost a month since Rick has logged on and posted something here.. :confused:

What is there for him to post? He installed it on his car, programmed the eManage and everything works great. Long term reliability info isn't something you can glean after one month. Not everyone is compulsive about posting every tiny detail.

I was under the impression that hewould be posting a time slip/dyno soon. Id just like to know exactly how much wheel horsepower Id be gaining by purchasing this kit for my automatic and Imnot talking about estimates either.

Here buddy Ive got something youcan use for the wild hairs youve apparently got stuck up your ass:

http://www.fullam.com/images/tools/153371.jpg

Jerky, I'm not the one with the attitude problem here. You are. Rick is a professional mechanic who made the Greddy turbo work in an automatic. First you insult him by suggesting he's incompetent and blew up his engine, then you ask him for help by way of dyno plots and other information.

Meanwhile you asked me to call Rick in order to get your questions answered. Why should I help someone who's so lazy they're not willing to do their own work? I assume you have free nationwide long distance on your cell phone so it's not like the call would cost you anything except effort.

I cant go at it w/you any longer for sake of going too far off topic.

Im trying to get this thread active again. Clearly there are other owners interested in Ricks work. Some are even considering installing the kit on their automatic Rx8s as well (Im one of them).

Right now Im torn between spending x thousand dollars on a kit + all the additional parts and tuning necessary toget the thing to run properly on my automatic - or getting a new car.

Sue me for being inquisitive on the onlythread w/evidence that the Greddy kit can work on an automatic Rx8.

I'd like an update as well.

I have not posted anything lately because I was trying to get the car to the dyno so I could show some hard numbers. It is hard to get the car to the dyno on the weekend and work around family commitments. I am hoping to soon however.
I have put about 2000 miles on the car with the turbo on it. The only recent changes are I changed the mapping on the e-manage. I am now running the primary injectors on one fuel map, and the 750cc secondaries are on the sub-injector map. This way I find I can fine tune the mixture better than having all 4 injectors on the same map. I also installed an HKS EVCIV boost controller. I was hoping to keep the turbo install as simple as possible, but I found that when the car upshifted to the next gear, I was getting a boost spike of 1 1/2 to 2 psi. The boost controller smoothed this out to only about 1/2 psi. I am still running only 7 psi.
So far the car is running great. I highly recommend the turbo install. It really transforms the car and makes it a lot more fun to drive.

So Apex8, since the cost of gas is going up (damn greedy bastards), has the mpg changed any. I know that keeping your foot in it would cause a change, but for the times at accel./wot do you notice any change in gas mileage?

09Factor

My gas mileage went from 19-21 mpg before the turbo to 17-19 now. I just filled up this morning and got 17.7 mpg. My typical driving is 75% 2 lane country roads and 25% in town. I did get as low at 9 mpg after installing the turbo while tuning the e-manage.

so performance still the same? 0-60 low 6 seconds?

I wonder what it will dyno at???? if the baseline is 140HP + the greddy 50HP = 190 HP that should be right behind or close to the Auto NSX which cranks 252HP -> estimated 215HP. The Auto NSX is also a 4 speed slushbox that weighs about 3200 lbs. The Auto NSX performance are:
0-60mph in 5.8sec
1/4mile in 14.4 @ 93.3mph

With good tuning the Turbo RX8 can hit that level for sure, but the bad thing is ... it just makes up our performance to the level of a basic souped up 6spd RX8...

BTW anyone actually dyno an AUTO RX8 yet? It didn't feel that fast especially barely outpacing a ford focus. WAHHH

This will be an interesting proposition for me if I would rather keep my auto RX8 vs. buying another one. I may just decide to trade it in on a manual though at that point (or the rumoured SMG)--it all depends on my finances.

Wish me good luck I am going to my dealer they have a used ti grey on their lot with 24k km no mods was owned by a 54 year old man and also has no declarations.
I will be trading my car wih the 800 dollar alarm and the 180 dollar tint job. Plus we are negotiating a trading in price hopefully I Have to give no more than 2k. LoL
But we will see i just dont see me spending 4k american to get my car going as fast as the 6sp. when i can use that and get a stock 6sp on warranty and than go for turbo :)

Good luck Hitmann--I feel that rationale, in retrospect for me to boost my auto RX8 I would need at least a low to mid 5second 0-60mph guarantee. Maybe down the line more powerful turbos will come out for the auto (SSR or RE Amemiya).

It is just disappointing why they had to restrict the automatics. Even the Auto NSX was disappointing. Toyota got it right when they made both cars 320HP (crank), look how many Auto TT was bought. It seems like almost 50/50. I would've got the 6spd but my girl doesn't want to learn!!! DOWN WITH IGNORANCE!!!

I don't care about 0-60 #'s too much. I do care about 20-70, 40-70, etc. And though an AT with the greddy kit gets you to 60 slower/as slow as the MT from a stop. 5-60 would be different i think. The torque curve you'd get from the turbo would make a lot of difference I believe. But a 3500rpm stall, torque converter would help :p .

where is rotarygod and mikeb on this subject? call in the master at machines and the man who wanted to be the first to soup up his auto.

http://www.bulletproofautomotive.com/catalog-detail.php?ID=3510

Don't know if you guys have seen that, but I know the kit RE-A was talking about was for an auto, perhaps thats it? I'm really not sure, but thought I'd post it for those who want to explore it further.

Yes, that's it. Made by Greddy/ Trust. A bit too expensive though.

A quick question to Apex 8, how is the transmission pressure thingamabob working? I think I understand the what it's doing but curious if you feel that it's helping keep the trans together.

When reading Moostafa 29s post, I think I see that the Gready turbo offered for the auto also has a chip (or something) to reset the redline. Am I misreading the add? I was under the impression that more RPMs would blow the trans.

bump. Anything?

I was think about the pressure riser too. Any updates how its been working?

Great to hear an Auto 8 has a Turbo finally.

I would go the same route as Hitman though.

Any news? I'm getting frustrated.

I talked to Rick a few weeks ago, and he wasn't having any problems as of yet. I believe he has had it on a few months now. Call up his shop and ask for him. I don't have the number, but you can type in Rick's Rotary on google and get it. Nice guy, I'm sure he'll ease your mind.

Rather go with RE Amemiya, 256 whp, Going down to 6.4 seconds I would say that's about 215 whp, IF THAT. We'll see.

tell me how the turbo is be
cause i am thinking to put one in my car

Bump for transmission info:


Where did you get the shift pressure riser, and is it working?
How similar is the tranny to the FD's? Would rebuild kits be interchangeable (like level10's stuff)? Do you know anything about the torque converter (size, rated stall speed, etc)?

TIA

Will you auto owners have any problems with the Tranny?

Update please?

P.S You guys are saying your getting over 8 seconds 0-60, I've used a stop watch and got myself at 7.1..BTW I have a spare-tire in the trunk and a sub and I weigh about 215 so imagine what I would do without it..

stopwatch isn't accurate

I don't know how the hell you managed to get 7.1. You must have pressed start from 10mph or something. Best I ever got was 7.9, and again...that was a stop watch which isn't accurate. Also take into account that the RX-8's speedometer is 2mph faster than what you're actually doing so 0-60 in this car is more like 0-62 mph. The only way you'll get an accurate reading is at a dyno.

Really one of these days a bunch of automatic owners should get together and pay for 1 dyno or something just so we can finally know what it actually does. I don't even own an automatic anymore and I'm still interested in hearing the true times.

how far away is coconut grove away from Belleview?

very nice !!!!
I'm a EU 4 port driver with manual transmission. With manual gearbox the 4 port engine should run in 5.x seconds 0-60mph. My car runs 7.4 0-60mph.


THUNEON

VelociRedBeast I've never even heard of Belleview before but I just looked and it's near Pensacola. I'm all the way at the bottom of the state so it would be a long ass drive. But look at this and try to tell me your automatic 4 port is faster than a manual 4 port:

THUNEON

I think what he was trying to say here is that the UK version of the 4 port (which only comes with a 5 speed manual transmission in the UK, not automatic like ours) does 60 in mid 7s, so he believes this turbo kit would put him in the 5 second range.

He's probably right since the UK version of the 4 port allows for launching the car at high RPMs (manual transmission) and you a have transmission that weighs less too.

7.4 seconds sounds pretty impressive to me for an NA 4 port rotary engine.

If only our automatic would have been capable of that I probably would have ended up keeping mine.


VelociRedBeast: If the best his manual 4 port can do is 7.4 seconds, how do you expect anyone to believe an automatic version of the same engine does it in 7.1?

Its not only a UK-version.
I believe it's sold all over the world except the US.

I have this version myself,but I've never tested it.
German car magazine Auto Motor und Sport tested 0-100kmh(0-62) in 7,7 sec.
Factory numbers are 7,2.
Factory numbers for the 6-port is 6,4,but it's some tenths slower.Just under 7 sec.

I'd like a reasonably priced turbo myself. I ran the 1/8 mile in 11.6 seconds at 64.6 mph. Pretty pathetic.

I don't own an automatic anymore so I don't really watch this thread the way I used to, but I can't believe the guy who installed this turbo on his automatic hasn't posted on here for this long. That's pretty disappointing. Oh well.

update please!

Is Apex 8 the only AT that has installed a turbo? Since he has not posted in quite a while I was hoping someone else would have tried it. I have been waiting for a s/c but I am loosing patiance with the wait.

Perhaps more folks will take the plunge after the warranty is up.

Perhaps more folks will take the plunge after the warranty is up.

exactly, i'm not going to void my warranty unless i'm gaining 800 HP

So is there any news on how this turbo 4AT is doing? I have an auto and thought about getting the Greddy turbo for it when i get the money. At lease now I know its been done...

theres the jap one and thats all i have ever seen! jump on a jet and bring it home!

well... I emailed the owner of this car for an update...

http://www.rx8club.com/showthread.php?t=71283

RE Amemiya's kit (http://www.re-amemiya.co.jp/new_parts/rx_8/04_rx_8_turbo_kit.html) requires the change of "main" injectors (I assume that means primary).

What's a ballpark figure for getting my A/T boosted?

it would probably cost the same as boosting a 6MT. It would be the cost of the turbo kit and fuel management. I don't think the emanage that comes with the kit works for the A/T. Maybe if it can be unlocked, you can make a new map. If not, theres always other options like emanage ultimate or the Interceptor-X (whenever they come out with one for the A/T). It would also be wise add a tranny cooler and maybe a second oil cooler.

So assuming the e-manage that comes with the kit'll work, just the cost of the kit (about $3k) and tranny cooler(anywhere from $50 to $200). Oh, and, of course, the cost of installation and tuning....

Anyone feel free to correct me or add something if I'm worng...

your not wrong ^^^^^

if you look closley at the Amemiya set up it also has thier Dolphin back box ect on BUT notice its pushing out 270bhp at the wheels!

That is awesome, a turbo in an auto, does anyone have the numbers after he dynoed? Hp in the engine and the rear?

Bump!....

i just turbo charged my automatic 8 i am guessing im the thrid one to do this since i know of only 2 other peopl on this forum who have im taking ym car to get tuned sometime this week ill let you all know what kind of power im looking at. but im already enjoyiing the boost in the car and its only at 5lbs haha =]

^^^Can't wait to see your 0-60 times and a dyno!

Congrats!

What kind of engine management are you running? Are you running the standard greddy kit?

Please keep us informed.
Are you running the base greddy kit by itself or did you upgrade it any?

Yes, keep us informed :)

Wow. I forgot about this thread..
Rick is #1, I'm #2 spots 3 - 5 are up for grabs. This is Stateside of course.
Its really eye-opening to look back and read these old threads.

i assume if a turbo'd auto gets the greddy setup, they must also purchase an int-x or cobb AP on top of that? why doesnt the emanage work?

im number 3! haha well right now guys im running the kit as is with the emnage ultimate. the problem with the emanage ultimate is that its tuned for manual transmissions. im experiancing some difficulties with it because of that i have occasional back fire if i dont drop into nuetral when i want to slow down and boost spikes inbetween shifts but because the emanage is limited to letting you only go to 5lbs of boost im safe and when i spike my boost it only stays at 5lbs but im tunning my car this week. my 0-60 timing has improved a lot. i think im deffinantly in a 5 second range and when i tested it i didnt shift any higher than 6k rpms. i will deffinantly keep everyone updated. btw though the greddy rs bov sounds orgasmic :boink:


ps - when i do my tuning im going to run it at 8lbs of boost :yelrotflm

How do you have your WG plumbed? Are you pulling the vac signal from the discharge pipe of the compressor side (preferred location) OR are you getting it from the intake manifold (will cause boost spikes and compressor surge)?

Also if you are getting spikes in-between-gears. You may have teh BOV to tight. If you have the WG pressure line plumbed to the compressor side.

you want tight enought to hold boost but loose enough to release that boost when you let off the gas. The backfire is caused by the BOV venting. The AFR go lean -rich- lean then go pop.

Also Since I noticed you have a '05. how do you have the harness wired?

just some thing to consider if you havent already.

i'll be the the 4th one to turbo my AT. i'll join the wagon soon.

don't worry bro. i'll definitely keep you guys updated. rite now i just won an auction off ebay for used greddy turbo kit from Mazsport.:eyetwitch

I talk to rick a week ago and asked him how his RX8 AT turbo work, he told me that his AT tranny broke and it cant handle the power. I know there is 3 AT with turbo now, just wondering how is your tranny doing and keep an eye on your tranny, I really hope that OEM tranny will work with daily driving with turbo. Rick also told me that there is a place call level 10 transmission, and i called the owner said he can make your AT 8 to a bulletproof tranny up to 1000hp, price are around 6000 dollar, i mean if i have the money i want to make it to 500hp will be cool, that is a sweet dream isn't it. Beat the GTR just like RX7 compete with R34GTR.
So i just want to ask the people who have AT turbo what boost you have it on, and how is your tranny doing.

Threadsurrection!

The E-Manage will work on the AT with re-wiring. Ask 09Factor.

Even with re-wiring, it have nothing to do with the tranny right? what are the safe zone for HP and TQ for AT turbo?

I wonder how much power Rick is pushing then.... I have spoken with him in the past and the flex plate cracked at one of the mounting studs.

Yes it is.

So i just want to ask the people who have AT turbo what boost you have it on, and how is your tranny doing.

9spi and no real issues. I don't brake launch or smash on the gas away from a light either.



Even with re-wiring, it have nothing to do with the tranny right? what are the safe zone for HP and TQ for AT turbo?

The re-wire only changes the way the Secondary injectors are handled. The way mire are/were wired is an "intercept" mode. Once boost is brought on, the EMU takes total control of the Secondary Injectors.

Hey 09Factor I just want to say thanks for sharing, i also want to ask that how much $ you put in your car to get your turbo set up if you don't mind, what parts did you get for your car? any radiator upgrade display gauge or anything, i am really planning to save enough money so that i can get them install at once to save labor. Thanks again.

I think the person that help 09Factor install his turbo are a very skillful mechanic, i wish there is more good tuner in the San Francisco, i guess the good one don't live in the big city. SAD :-(

07 AT tranny no good for turbo?

just tuning

The 07 + Rx-8 is an easier canidate for FI. just because it's a 6 port motor there are many more availble maps

Hey CbRotary. Attached are the requested pics of the vac source for the boost gague and BOV. The other pic is of the vac source for the Wastegate coming off of the turbo's charge pipe.

If you don't mind can you tell me how much total you spend on your turbo? what kind of tools you have other then gauge and cobb?

To date for AFR sensor, Boost and AFr Gauges, used greedy kit, + rebuild kit for tubo, new sillykone hoses, hi-flo meow meow, and some payed labor and tuning.

$3825.
Doing it yourself saves a boatload on labor dollars.

If your willing I can probably set something up with MM to get your tune right.
Do you have the AP yet?

If anyone with an a/t is going to use Interceptor X, I have one for sale. Shameless advertising I know:)

No AP yet, but i know it's a must.

dave i just finished doing the t off tonight i winded up putting it on the intercooler pipe that connnects right to the top of the turbo because the turbo is in such an ungodly area that i was not ever goign to rip that shit out again lol so i winded up putting it as close to the turbo as possible and it worked good im still spiking liek one or 2 lbs but nothing major liek before but idk i know im atleast spiking 1 lbs of boost i need to get on my car more and see if thats all. thanks though for the pics. :)

Do you have the boost controller on or off when you see the 'spike"? I don't remember from yesterdays conservation?
If it's on which it sound like it is, turn it off. Go for a drive and you should see around 5psi.

actually i dont have a boost controller in yet i had ordered the mms by greddy and mis understood it and thought it was a boost controller and it is not so now i have to retur it and need to get a boost controller but i want a simple boost controller nothing crazy. i just want one that has 2 modes A and B. what kind do you have cause i dont want a manual one and i dont want all the crazy fancy gadgets lol


suggestions?

thanks i was actually debating about that one too

Do anyone of you know what's the difference between RE-Amemiya trust turbo kit and Greddy's? I know they are the same except the computer set up. And according to them it can push 240 or 270 ps and when Rick's rotary install the greddy turbo on his car it blew the trans. Is that mean that Somehow the RE-turbo are more reliable and difference than greddy turbo that have to be adjust?

just to let you guys know. apex8 aka rick from (rick's rotary performance in pleasanton, ca) wouldn't do a turbo installation anymore on rx-8. the last time i talked to him regarding a turbo for mu automatic , he said he wouldn't do it and he doesn't want to get involved if anything happens to the engine.

I hate to say but i am agree with you after seen so many sucessful auto turbo, I don't get how did he break the tranny.

BTW, its sad that san francisco bay area have no body are good enough to do auto turbo rx8. especially when there is so many resident is sf bay

I travel!

Did he break a 4-speed tranny or the six speed automatic? Seems that the 4AT tranny has been one with the least amount of problems with the tranny itself. (knock on wood).

out of all the RX-8 transmissions, I mean. I haven't heard of any tranny specific problems with either of the automatics.

Well he told me its a 4-speed tranny(unfortunately), He said that he wasn't running in a high boost, he have her wife use it as a daily driven car. I really wish that tranny thing he said is untrue because I really want to install a turbo in my car and that's the reason stopping me from installing it. Please Help!

I know 09Factor has been running a turbo on his 4AT for quite awhile. Phil has been running a SC on his for quite awhile.

I know at one point I mentioned that he cracked the flex plate, (the auto equiv to the flywheel). but other than that, IDK. That was over a year ago.
I know Phil has been harder on his trans than mine. Just because his is driven more.

MM travels and has had ample time to blow up an auto between Phil and myself, but for some reason hasn't. It could just be the magic he brings with him.

i talked to paul from Rotorsport ( a shop in santa clara, ca). he is willing to do if for me.

You think Rotorsport will do fine? I know install a turbo on MT rx8 is easy, But on AT rx8 lots computer tuning require.

i have a 6port automatic rx8.. these are my recommendations when turbocharging (this is what I will do)

Cobbs AP-I will change my rev limit to 8700 rpm, therefore i will need transmission coolers.

I have dynoed my automatic bone stock rx8. at 7500 rpm it makes 158 whp. Thats real real close to what the manual does at 7500. Generally the Renesis makes more and more power until about 8500-8700 rpm. So theoretically I will be real close to the peak hp of the manual rx-8 IF MY TRANSMISSION CAN HANDLE IT, when I switch my rev limit.

I will be installing a T3/T4 turbo. I've never heard of or seen an rx-8 with a T3/T4 turbo. I've seen plain T4's (PTP turbo kit). But the T3/T4 has a faster spool up time, helping the car's 0-60 ALOT, being that the auto can only launch at about 2500 rpm. I just hope and pray that the transmission can handle the power.

what are ya'lls thoughts about this?

Thanks for sharing it is really helpful to know, I think its safe just have strong boost under 4000rpm when it pass 4000rpm have the cpu lower the boost, because that is when RX8 high rev power comes in, we are basically just need stop and go power, we just need power under 4krpm. That will make the tranny less stress I think, and scramble boost will be nice dont ya think?

Freaklink! I see you made it to the forum.

I emailed you a while back asking about your manifold choice. How is your turbo project going?

The four speed a/t tranny is stronger than you would think - mine has be subject to 9000 rpm and constant shifting at 8000+ rpm. In conjunction with the AP it is still working very well.

Hey Phil, Do you think maybe Supercharger are maybe less harm to the tranny? because you are having supercharger or you think they both are the same?
Thanks

Boost is boost - the trans or engine does not care where it comes from. Will I eventually need a new trans? You bet I will but not now or in the near future. Most likely not a new trans but rebuild and beef up.

Did Cobbs AP also turn off the speed limiter on the car?? if so how fast how you gotten the car up to?

American-spec cars don't have a speed limiter.
At least the '04s don't.

I was going to use the obx headers at the manifold.. but I changed my mind. I'm going to use PTP's turbo mainfold. Thats who's hooking up my turbo from
Austin, TX. Im also getting the Pettit Racing intake mainfold. They said they would sell me one for $400

my 2006-6speed auto shuts off at 125mph

My 06 auto also shuts off at the same time...:icon_no2:

The 04 doesn't have a speed limiter. Or should I say mine goes past 125 mph.

paul from rotorsport had worked on bunch of rx8's. he used to own a rotary engine car i dun know which one. and my AT engine is the same engine with MTs, so it should make the installation the same with if you would to drop the turbo into MT's. part of the problem like you said maybe tuning.

Hmm....My 4speed have speed limiter

I can't speek for every a/t but mine never had a speed limiter as I had mine before the s/c to 135 +/- speedometer correction. You would have to ask MM if it turns off the speedlimiter, if yours has one. It does turn off the forced shift points of an a/t and lets you go to your new redline (& beyond) so use caution when/if you pruchase an AP. You can of course blow the whole mess if you go beyond a certain point (?). I just set my personal limit at 9000 and everything has held together. Since the addition of the AP the whole combo runs smoother.

is it just me or somebody else. it seems that my AP did not raise my redline at all.

I don't think the AP increases redline on all tunes. You can ask Jeff to increase it but ask yourself if you really need / want that...

You don't need both. Your choices basically are Emanage, IntX, or Cobb.

As far as upgrades, depends on what you plan on doing with the car, and how much boost you plan on running. If you are not planning on tracking the car and sticking with the stock boost levels of the greddy turbo kit, I'm guessing you would be fine as is. If you plan on going for higher boost levels, at the very least you'd need fuel system upgrades. If you plan on tracking the car, you should look at upgrading the cooling systems.

yea...i autocross

also the ignition system at higher boost levels. :)

If you autocross, my best guess for upgrades (assuming the standard greddy 6 psi) would be make sure you do something to get the fans on sooner (like Cobb AP or Mazsport cooling fan mod). I would also recommend a second oil cooler. You can pick up a used cooler and lines from a parts car, or you can hit up Mazmart for a new one. I'd also recommend switching to a more water-heavy coolant mix. The Mazmart water pump is also a great idea.

If you get all that and still end up having cooling issues, you can also look at Ray's radiator.

took me 27 hours to install mine....not a walk in the park..that's for sure. I have a 6 speed tho..don't know if it's different with the at's....
