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.
