People need to realize that Greddy releasing there kit is more important than just them having a turbo kit out. For better or worse, Greddy seems to be the market maker for aftermarket turbo kits, thus once they come to market others tend to follow, and price around Greddy’s price point.

People also tend to reverse engineer, improve, augment their kits as well as leverage Greddy’s R&D.

In addition, there seems to be some “tentative” consensus now that the emanage can handle to low/mid boost applications, which is a major FI victory as the ECU was the real nut to crack. Sure, a custom ECU would be better, but, the emanage is a known device and a lot of folks are already working with it through Canzoomer.

I look at the Greddy kit as more of the beginning of the FI wave for our car. Finally, I know that in about 12 months we’ll get the first real long-term impressions and effects of FI on the Renesis engine.

 

true true....time to start saving money now in abotu 12 months my warrenty will be gone...then it's fair game for some crazy upgrades

 

Exactly my point.

 

Just got my car back and put about 15 mild freeway miles on the odo... won't be able to drive it again until I get back in town in 2 weeks. What kind of 'real world' pics do you want me to take?

We've seen most of the pics and most of us are probably more interested in your initial driving impression turbo vs. stock.

 

I don't think the Greddy Rep. knows what he is talking about. It is not 300 whp, it is 300 hp at the crank. The +60 hp gain would put it in the 300 crank hp range. 300 whp would be about a 120 whp gain as most RX8's are running about 170-180 whp. Even Shawn's unit went from 170 whp to 235 whp, so 300 whp from this kit sound very unrealistic. From the SSR/SFR maybe, but then again that kit seems to be much more high end than this kit (more $ too).

 

ditto, quite a cliffhanger you left us with there...

 

I´d still would like to see this kit mounted without all the enginecovers... any other pics available that´s NOT from sema?

 

Not the "show and shine" from a car show...but a real person's car with the system installed in it.

 

That too! :D

 

has anyone tried calling mazdatrix to see if they actaully POSSES this kit? maybe it's jsut a prereleaese picture and info?

 

Snoochie, air-to-air intercoolers don't "pump up the boost" as you credited me with saying earlier. What they do, at best, is reduce the compressed intake air charge back down to the same temperature as the ambient air so as to reduce the possibility of detonation and to get the most efficiency out of the boosted system. My comment on the I/C was based merely on the photos I have seen of the I/C included in the GReddy kit. It seems to me that the I/C might be a bit too small to deal with anything more than the GReddy-intended level of 5-6 psi because of it's somewhat small size and two-row design. With those limits, I am wondering if a turbo kit might even be worth the trouble in my case because I already have something that works and to get another 20-45 h.p. out of it requires just an ECU and some jets in the nozzle. No doubt that to have both a turbo kit and mild nitrous would be rather compelling even if the total output is still the same. That's the decision I am weighing right now.

Let me relate my experience driving the nitrous-boosted RX-8 and see if Shaw's turbo feels the same: With the nitrous activated at WOT, the engine has only a small increase in torque below 4K rpm. As the tach needle sweeps past 4 and moves to 5K the boost begins to be felt in the seat-of-the-pants, and by 6K all the ponies are coming on HARD. Anything above 6K feels like a whole different engine.

p.s. This story is not intended as a pro/con on the turbo vs. nitrous debate. Just a story to let all of you know what it's like to use the nitrous.

 

Thank you for that review.....ok Turbo your turn :D

 

No, but I can...let me get some free time this afternoon.

 

Can't wait for your impressions after some seat time...keep us abreast

 

Well, I just called Mazdatrix. They have 3 in stock. Well.. make that 2 in stock since I just bought this from them.
The kit comes with a T618Z turbo, exhaust manifold, down pipe, all the piping to include oil lines, couplings, wiring, pre-programmed ECU piggy back (e-manage). I'm going to have it put on the day I recieve it. I'll keep you guys in the loop.

The guy at Mazdatrix told me that they should have the other 2 sold by the end of the day. So hurry if you want it.

 

I dont want real world pics. What I am looking for is a video. Any digital camera now a days has the ability to take video. Try and post that.

Also, since you have worked closely with GReddy, is it possible for you to obtain dyno graphs? I would love to check out the torque curve compared to stock.

 

Greddy is one of the best in the Aftermarket Industry. Their products are top-notch.

 

Charles, I think you are a little optimistic if you think you can get back down to ambiant temp with an A/A IC. If you get 50% eff out of it you can only reduce the temp by .5 of the delta. Meaning half of the difference of outlet temp and amb. A liquid IC does better but is not as renewable per given time. On the other hand it is not dependent on air speed through the grill.

 

Don't you think you have enough mods already...

 

How strange that it's already being sold yet left completely off of their own website..???

 

even if I was ready to buy, I wouldn't buy it from Mazdatrix since their prices seem a little higher than other sites like hopupracing, im-motorsports, etc. Plus, if you live in CA, you have to pay for sales tax buying from Mazdatrix.

 

sweet congrats on the purchase..i now officaly hate you:p haha soooo lucky. can't wait till you put it on (are you doing it yourself or having a shop install it for you). please please please post lots of details:D

 

Thanks. I will be putting it on with a buddy of mine at his shop. He's a rotary mechanic and has a lot of experience with rotaries and turbo's It'll be about 10 days or so until I recieve the kit and install it. I'll start up another thread then with pictures and details of the install.

 

sweet...is he pretty good? maybe i should roll up to NJ when i get enough money to get my own turbo (which happily enough will coincide with my warrenty ending..hopfully cross some fingures and toes for me:D)
