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. ________ Marijuana Vaporizers |
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.

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.

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. |

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 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.

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...
https://www.rx8club.com/series-i-engine-tuning-forum-63/auto-rx8-greddy-turbo-what-ecu-do-i-use-71283/ |
RE Amemiya's kit (http://www.re-amemiya.co.jp/new_part...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 ^^^^^
