Yeah, I think Broke Apex Seal's experience with the CEL fix effectively scared all of us away from that.

It's easy to say/claim that the Greddy turbo kit is a joke, or that there are better alternatives, or it doesn't give enough hp. But name me something for $2800 that does better. Like Richard Paul said before & I agree with with him. The Greddy turbo kit is a good street kit, and a good value. Everybody jumping up & down saying the SSR/SFR & the PTP will be better. I agree with you as well, but you are mis-stating/ not stating one big fact. It will be probably $6K+ for these kits when they do come out. They compete on entirely different markets. That's like saying a Porsche 911 is better than an RX8. Duh. I'm sure the PTP kit will produce 300+ whp & looks like a phenomenal kit. I guess it's just a matter of good (stock RX8), better (Greddy turboed 8) & best (PTP turboed 8).

Yer walkin on thin ice there buddy...

exactly what fanman said..
while Greddy might be a pretty nice street turbo kit with a kick *** price,
it it not the best out there. You're talking as if the Greddy kit is the god's creation or something lol? and you want me to shut up because i have no experience with turbo?
and how would you figure that out? My last line up of cars include 300zx tt and turbo eclipse. While you may justify urself with greddy turbo as being the best for NOW, soon you'll see better stuff coming out. I have already been in a greddy turboed 8 with 260whp, and I was impressed. But would 260 whp satisfy me in my rx8? Like you said, I could've bought a charger for cheaper, but I believe my 8 can alot better than 260whp, its just the Greddy doesn't meet my expectation. Once my expectation is met which i believe will be around December, my 8 will be about 70% faster than your slow 8. LOL

MadDog

c'mon, dude. stick to your guns. Is it a kit with a

or is it a


I can accept that you want more power. I had neither the resources nor the desire for more. You missed the entire point of my rant: people with no experience driving this kit want to bash it and in my personal experience, its seemless HP added at a bargain price. My ride is neither bumpy nor rough. Out of the box, it felt like it came from the factory the way it should have - with about 275 real HP at the crank. Before I even started tuning, another forum member drove it and had the very same impression - feels like factory power.

Also, consider that given that the GReddy is so much cheaper than any of the numerous other UNavailable options currently on the market, there are going to be some people who attempt to install it themselves and end-up f*cking-up the install, or the tune, or the BOV will leak.... Its just so much more available to people. EVERY kit that comes out, REGARDLESS of price or output, will need to be tuned. I'd venture to say that those kits that have a higher output will perform worse with the out-of-the-box fuel maps than those with lower output. Its simply a matter of taking the Renesis further from the factory configuration. You're going to have to hold its hand the whole way. There will be people who install the PTP tuner kit and get crappy results, just like there has been for the GReddy. That won't mean the PTP is a bad kit. It means it got a bad tune from Billybob. It has different goals. And, just like the GReddy kit, I won't want to hear people bash it unless they have some personal experience with it.

Gerael

i read a thread about some guy tuning greddy turbo.. and that boost drops off at high rpm cuz it just can't push enough air...

isn't this a major disadvantage of the turbo the greddy kit uses?

rather get a bigger turbo and down tune it...

This debate will continue forever. I believe I even wasted my time with evilbada, or some other forum member, trying to argue a similar point. After awhile, I just said forget it. There is no point trying to convince someone who already has their mind set, and is too ignorant to listen to and understand someone else's point. (Notice I said listen, not hear) You can have all the turbo experience in the world, but unless you have either riden in, or driven a GReddy turbo'd 8, you have nothing to base your opinion on. Everyone has already admitted that the PTP/SFR kits will be more powerful, its a given. For 2-3 times the price of GReddy, I'd hope so. Now is it better? That depends on what you are after, and your own personal goals. Personally, how much better can you get than a $2800 kit, that gives you a good 80-100whp extra? Yes the other will give you more power, so if thats what you base your "better" on, then I agree. But I base mine on the value, and power advertised and delivered. But to make a long storty short, instead of always arguing like you have experience with a GReddy'd 8, go drive it, do your homework, and report back. Until then, stop wasting everyone's time. Thanks!

evilbada1

Greddy kit is a nice street kit that'll up your midrange power BECAUSE it has shitty turbo and shitty fuel management system. When it goes up top, eh..you know better.
I'm tired of such debate also, and no it wasn't me that moofasta wasted time on.
Let's just stick to what we believe and respect our opinions.
I'll respect your side of opinion that Greddy turbo gives most bang for your buck while my opinion will stay as Greddy turbo kit is **** and I want something better as far as turbo and fuel management system go. I won't post anymore regarding this debate anymore :P

"I offer you a truce. The stickiest of the icky. Come on and smoke with me Charlie Murphy"

Fanman

That's a fact.

My current setup goes to 7.5 lbs. of boost, then drops off to 5.5 lbs. like everybody elses does (see Mazsport's video). Not a big deal for me as it is pretty much for everyday driving. I wanted more power on the low to mid range anyways. Every turbo has tradeoffs. If you get a turbo that is sized too big then it won't come on until the mid to high range (get lag). ball bearing turbos have alleviated this somewhat but there are still tradeoffs.

It is really up to you on what you are looking for. For me there was no way I was/am ever going to pay $7,000 for a turbo kit no matter how good it is. For some people ultimate power is more important. My car is a daily driver & I plan to keep it that way. If they had an roots/lysholm SC kit for the same price & out now (or when I bought the kit 6 months ago. I probably would have bought it then as I wanted low/mid range power. To me the Greddy kit is fine.

evilbada1

And PTP's GT35R isn't exactly ultimate power oriented turbo either.
It is such a street turbo.

Greddyturbo1

Maybe I should'nt say anything, but as per my previous statement(above) I feel the greddy turbo is


1. The best deal out there , right Now
2. Has been the only one to prove themselves out there.
3. And the greddy kit with some tweaking should be able to put around 350whp
and that's a Damn good horespower increase in that price range..

I'am not saying the greddy kit is the best, but they are the first and are putting out good HP numbers for anyone who wants to tune... Perfect No, but after more tweaking I be very happy with around 350whp from my Greddy...

As the Newer units start hitting the market I'am sure it will get easier for us to tune and abstract more power, But I'am not waiting 6months a year or a day,
I'am having fun Right Now with 284whp and that's a big change compared to what
I had before, And will push the car more (the right way) to get to my 350whp...

OfficerFarva

I like the way u summed up the kit. I've been boosted for about 3 days now and i can'te even floor it yet and it pulls like a SOB untuned! I really notice the pull in 2nd gear, as well as higher gears like 4th and 5th. I don't have to downshift to go up hills anymore, just a little throttle in high gears and this thing moves! Gotta say, for $2799 w/ free shipping I think thats a deal. Like u say, definitely the best bang for the buck out there. And i agree, with tuning 350 whp is definitely in the cards. Good luck!

MazdaManiac

iTrader: (3)

I blew mine up.

Oh, thats right.

No I didn't.

Sorry for the confusion.

Well, even if I did, mine is just a Greddy knock-off, so it wouldn't count.

I'm closing in on one full year of boost and no problems, no smoke (my earlier idle smoke turned out to be the crank recirc) and no bogs - and that is with an E-Manage.

I don't think anyone that is still N/A should be allowed to comment on the value/quality of any FI product.

MadDog

I second that. Its re-goddam-diculous....

Fanman

I'm sorry, maybe I missed that part of the discussion, but when you say you are going to get 350 whp you do realize you will have to take the turbo in for modification right ? No way are you going to be able to get the stock Greddy turbo to push 350 whp. Manuel (from PR) was pushing about as much boost as you can physically push through the thing and he was getting just over 300 whp. I just don't want people to think that adding a different fuel management unit, or tuning the Greddy ECU is going to get you to 350 whp. That's when things are going to start adding up (different fuel management unit, modifying the turbo, new fuel injectors, etc) At that point it really takes away from the key point of the Greddy turbo kit (VALUE) & people should consider the other upcoming kits. For people with an exisiting Greddy kit, more power to us to modify these things, but if 350+ whp is the goal then the Greddy kit is not/should not be the place to start/end

evilbada1

I just wish the Greddy turbo was mounted somewhere in the engine bay with the heatshield on the hotside, so with a little amount of work, the turbo could be changed...
If that was the case, I would've definitely bought one already..

OfficerFarva

well, yes sum turbo upgrades would be needed. But ifu think about it, getting a bigger wheel for the turbo and aftermarket fuel lines, injectors and definitely a better intake system, you could hit much higher numbers and still have less money in this kit than buying a $6900 kit like the speed force racing or whatever the other kits will cost. So in a sense, still great value even w/ upgrades.

OfficerFarva

o yea, and a clutch....thas kinda important .

Sapphonica

I'll buy a beefier clutch when the stock one fails.

I hold 7psi of boost up to the redline by using the E-01's RPM offset feature.

I did a little experiment & saw 8 psi. There was plenty of % left in the RPM offset. Therefore, the stock GReddy turbo will hold 10 psi to redline, easily.

How hot the air will be at 10 psi is another question entirely. There might be a higher mass flow rate at 8 psi than 10. I dunno.

OfficerFarva

o cool. yea that would be interesting to find out if 8 psi was atually making more power with the stock greddy set up. I wouldn't doubt if it does to be honest.

Fanman

If you do a estimation :

Greddy Turbo Kit = $2800
Upgraded Fuel Management Unit = $1700
Upgraded Greddy Turbo = $500 (estimated)
Upgraded Injectors = $400
Total = $5400

At that point one has to decide if it is worth it. You might (and there is a BIG Question Mark on that) get to 350 whp with this setup. Whereas the PTP kit is looking like 325-350 whp is the starting point with more potential up top. What the Greddy will give you is flexibility. Start at $2800 & 230-240 whp. If you decide that is not enough then you can get the upgrades later.

OfficerFarva

O yea. And what u have to realize about the greddy is u can drive it daily w/o worrying about other major suspension upgrades or necesary tire upgrades. Yea, i would love to get better tires and more than just springs eventually for my handling pleasures, but w/ 325-350 starting, u kinda wonder what u would have to do to the 8 to make it driveable, or at least fro sum1 like me who drives the car every day.

Greddyturbo1

Fanman, What is meant by me saying I 'am looking to achieve around 350whp with the Greddy is...
1. Yes I will be sending in the turbo to modify it.. Keeping the same Greddy Turbo ...
2. I like the location of the Greddy Turbo, Its hidden, there's not as much heat as mounting
the Turbo in front and high up, less heat around my carbon fiber hood.
3. And if you think the Greddy turbo can't be upgraded to put out 350whp , well you better really give that some serious thought, Because a couple of Daaammnn good tuners I know say absolutely.. That's not me saying this, its them...
4. You know some people have said not to push it past 6-7psi with the Greddy, I'am pushing 9psi and it's running Great...
5. Bottom line is you can make almost anything run good, just need to know what your doing.I'am not saying anything personal about you, I think your one of the good ones.

Fanman

Good luck to you & them then. I was more talking about the stock Greddy turbo. Will it make 350 whp. Absolutely not. I don't really know what Mazsport plans to do to the T618Z unit, but the stock unit even from their video is putting out 295 whp at 12.5 PSI ! Manuel (from PR) modified his fuel system, basically tuned the turbo kit to hell, & boosted to 12 psi and was getting a little over 300 whp. Unless the turbo re-work is going to be a massive re-work I just don't see 350 whp at a sane boost level. At what point will this just not make sense and you are better off going to a kit with a larger turbo. I just don't want people to think that with a simple upgrade they will be getting 300+ whp from this kit. It is going to involve a lot of $$$ & cost. Not really directed at some of the posters on this thread, but more some of the people that might be reading this. Some have seen the Mazsoprt video or heard of the 270 whp from the kit (which is a phenomenal result) & just think 300 whp will be a piece of cake. I just want them to get a realistic sense of the situation, that it won't be as easy as just tuning the fuel management unit. If you get 240 whp from this kit be very happy. 300 whp is going to be some major work.

I am really interested in people's research on this kit (including my own) as well. I'm currently running the kit at about 7.5-8.0 psi as well, looking at a few other things that will allow me to go up farther safely. More power to you. We have these kits now, so why not play with them & see the limits.

Gerael

How much more boost can the renesis take? Does anyone have any data on how the engine interior is lookin? or anything like that?
