Unfortunatley , as much as I hate to agree with him Shaun is Correct. a T3 based turbo is useless for even a stock 2.8. Several people have Dynoed these on Pennocks with dismal results (150 RWHP)
if you want to make real power turbo-ing a 2.8
www.turboz24.comNot trying to be a dick , but if someone spends all that time building a proper turbo car , you need to properly size the turbo and not just guess @ whats a good size. The local Shop that builds cheap Turbo Civics here in oakville Uses T3's as their base stage 1 setup on SOHC 1.5 Vtecs. IF you go to a DOHC engine such as a ZC16 they bump the turbo considerably. Turbocharghing is a science and can't be guessed at.
