Right now it is a PT-61 turbo with a Garrett air-air intercooler. We put in 42.5pd injectors and a LT1 MAF. Corsa exhaustand ported manifolds. Had we installed the 60pd injectors we would have hit over 400whp. I was maxing the 42.5s. The only reason I didn't install the larger injectors was...
As some of you might remember I was planning on installing a turbo kit on my 04 GP. Well it is on and it is amazing. It is a PT-61 turbo with a air to air intercooler. We dyno'd and hit 384 to the wheels and over 400lbs of torque! It is stupid fast.
Turbos are more efficient then superchargers.
As for the ****** it should be ok. I won't be racing everyday and I always keep my maint. schedule. As long as I don't do 50 in reverse and slam it into drive I should be alright.
I have been reading about alky. Don't think I will go there though. This will be my daily driver. The other guy who has this install is running 11psi, 17 degrees timing and 0 KR. From what I understand it is a task keeping the SOB in line.
