Forced Induction - rwhp t74GTS ?
04-23-2007, 09:32 PM
I have a GT67 STS kit on my 6 liter S10 Blazer. The motor has a LS6 cam and stage 2 ET Performance heads. I am thinking of upgrading to a bigger turbo and was wondering what you guys think a T74GTS would offer over the GT 67? (The 74 was recommended by Precision Turbo today) They said to go with a .81 exhaust which I think is what the existing turbo has.
Thanks for any help....

whats the question? Ive seen a 74GTS .81 push 860 rwhp on a supra... I doubt it will on your car though lol

I guess the question is.......with all else equal how much extra power would a 74 make over the 67? I know there are lotsa variables and it is pretty much impossible to answer. But lets say it made 500 rwhp at 8 psi with the 67, with the improved airflow of the bigger turbo.....what would it do at say 12 psi and the 74?
