ive got a gt17 on 12psi and ive got boost from 2 grand rev's!!!
and suprisingly all the way to 6.5 grand rev's.....
i can boost in reverse coming out of the drive way!!!!!!
honestly i personally think a gt17 with ar .53 inlet and .47outlet is like the perfect turbo for our engines!!!
as ive had a t25g and was lag city.....and pretty much engine wouldnt go past 6.5 grand rev's unless u have forged pistons.
but dats just my opinion!!!!
(my gt17 originally comes on saab 9-3 2.0 turbo models)
although i purchased mine brand new. $400 on ebay
