I missed a step somewhere. Aren't the turbos you have good for a lot more than the 15(?) psi you're running them at? What do you gain by swapping kits that couldn't be gained by working with the existing one?

The combination of small T25 housings and poor design/flowing manifolds will limit maximum power. So you can put whatever turbo you want on there, you will always be limited to the turbine housings and manifold design.

If you compare any manifold to the F.I units, it is very obvious which manifold will flow more/better and produce much better results.

Remember this picture I took:

T25 .63 a/r turbine compared to a Precision T4 1.0 a/r (that is only a 1.0 a/r housing too, they go up to 1.32)

Whatever air the compressor pushes out, the turbine has to be able to handle as well.

The turbo I have now are rated at 480 each but I am held back by the log style manifold that come with the GTM kit and the small .64 A/R housings that I have on the car now.This is the reason I have been stuck and haven't ran anything more than 18-19 PSI. It is just to much backpressure from manifolds and housing's that I have on the car. I could just change the housing's with the manifolds I have now but the motor has to come out to do that. Pulling the engine in and out on these cars with a TT setup is not cheap.

In the end I am selling my GTM kit because the New V3 manifolds have not come out and I have been waiting a year for them. I would love to have the new manifolds upgrade my GT3071r's turbo to HTA billet wheel's 640 HP each. This would be very cost effective for me but I am just tired of waiting.

I'm a little lost.... how do we bypass the HP limit with VVEL? Eliminate it with an HR swap??

Not sure what you mean by VVEL hp limit the highest I have seen on one of these engines is 850whp it was a GTM car.

I thought that the engine was limited to under 600whp because of timing issues with the vvel. In order to bypass this limitation people were talking about head swapping with a vhr engine. I truly thought we couldn't keep going up in hp until vvel was cracked! Am I wrong?

Yep. The fast intentions guys are pretty much all over 600. One over 650.

More hp a lot more problems and issues follow.. Just saying..

COSMO · 03-24-2014, 04:29 PM

Great numbers but all of that power is at the end of the rpm range.

Not sure I agree.... 800 hp and 800 ft.lbs at 5,550 RPM

This ^^

Plus, it is coming from a 3.0 supra engine.

My buddy has a built engine for a G35 that can easily hold 1000+ laying in his garage. Sleeved, Twin pump and the whole nine. He is getting a kit from Sasha and putting the PT7675 (I think) on it.

His goal is what ever that hog will make.

Should be interesting.
