You will have to push the **** out of the little trust turbo to reach 350whp.
And even if that's possible, why would you want to maximize the turbo or even more?
Pushing it that hard will shorten the life of the turbo... ever thought about that Greddyturbo1?

Evilbada1, I don't understand the logic in your statement, You say pushing the turbo will shorten its life... Everything we do in life that we push hard will shorten it. Why would you want a turbo or Supercharger and run 2psi boost..What's the point in spending that kind of money, if your not going to push it, at least once in awhile.
I guess what I'am really saying is
1. we really don't know what's the max boost the engine can handle ,be it a turbo or SC
but rumors are that 350whp-375whp is fine for this engine..
2. The reason I would push the Greddy turbo is
A. the turbo is not expensive
B. I like the fact that , Because of the size of the Greddy Turbo, even when tweaking the turbo it will still give better Bottom end than going to a larger size Turbo.
3. And finally, I'am not telling you to buy a Turbo or SC, or what to do with it when you get it, I'am just saying , what I have and what I'am doing with it, you don't have to like it but that does'nt mean it wrong..... Thanks for listenning

the greddy turbo can't flow enough air (cfm) to make much more than 300HP. At high boost (I run it near 16 psi) it turns into a giant heater.
The 400HP rated on the greddy turbo applies for piston engines.....................
For a rotary engine is different.
Gerael,
how much boost can the renesis handle?
It depens on the turbo that you're goin to use,
14 psi from a GT35R is not the same as 14 psi from a T3
for example.
We feel save runing at 14 psi using GT35R, we runed 19 psi but we don't
feel save.................................

I know...........................
The best you can do is bore and install a bigger wheel (propeller)
this is not expensive this job here in PR probably cost $250, but how many more
cfm (lb/min) you would get........................
you would need to run higher boost to make more HP, but the only way to know how much HP you can make is doin it. So just go for it.
On one point I was thinking on doin that but at the end I prefered to use a GT35R
that can supply 65 lb/min. I can make higher HP gains with less boost.
I have a friend that damage his renesis engine runing 30 psi of boost.

the turbo in the Greddy kit is rated for 400hp. Its an 18g turbo, the same one they use in the EVO'S. The reason the boost falls of has nothing to do with the turbo itself. Give a call to Altered Atomoshere or Vivid Racing. They both have tuned the Greddy kit. As with any turbo setup, it takes tuning. Dont expect people without true Rotary experience to extract good results. A couple of my friends were running 550-600hp at the wheels on thier RX 7's, but they had a wealth of knowledge. The Renesis engine is new so its gonna take some time for tuners to adjust to it. And frankly most tuners just dont have the know how. But for now there are several Japanese tuner shops that you can go to for FI, Like Blizt, Knight Sports, Pheonixs and more. Pick up a copy of HypeRev and get busy.

The Greddy RX8 turbo is a T618Z. I've heard it's hard to find and I highly doubt it's the same one the EVO's use.
Vivid racing did a write up on their pepsi RX8 and how they fixed it all up and installed the Greddy turbo kit. They dynoed it but didn't release results... my guess is the results weren't what they were expecting.

18g is 18g. Greddy just uses different trims and such. The setup they use is thier setup and they will not release the maps because they dont want to be copied. Greddy uses Mitsu based turbos and HKS uses Garrett, etc. etc. Mazda has done some special things with this engine to insure its longevity because of what happened with the RX7, they purposely kept away from FI. Thats why all of these company's are having a hard time with thier kits, they cant get past the factory cpu. If the greddy kit didnt have potential then RE Amemiya would'nt use it, and they have some of the best rotaries out.

If its flowing 260-270 at the wheels its flowing 300 hp already. If Mazsport was running 291 at the wheels at 12.5 psi, its flowing more than 300hp, again. And at 16 psi what are you dynoing?

I myself have the Greddy turbo setup and do like it, EXCEPT for their EMS, blue emanage blows.
Did Vivid or AAM mention anything about tuning the emanage?

Dont point at so and so and say the have a kit coming out thats making such and such at the wheels. Thats all speculation. Get out the math and tools and make a better kit yourself, then show me you have bragging rights, cause you did it.
after that no help, guess they are waiting for the problems to be fixed from this forum so they can help everyone.

With the greddy the maximum that I maked was 305-308HP at the wheel with 14-16 psi..........We don't find any big difference on HP increasing 2 psi of boost.
With the GT35R I'm runing 328-335 HP at the wheel at 14 psi of boost. I'm thinking that
to hit the 350 HP I would need to install a bigger intercooler than the sparco that I'm using now. I'm goin to keep studing how we can find a few xtra ponies. The next step probably is the "pineo" to be sure that the the engine doesn't move..............
But moving from 273HP to 328HP is a lot better.............
