a T88 would be way to big for that little engine wouldnt it. And its not like he would need more than 25psi. A kid i know has an Eclipse GST with 420hp off the crank and he easily rapes vipers, corvettes and just about anything he comes accross. Check out these kits and this may give you an idea of what kind of hp you can get http://www.cybernationmotorsports.com/Turbokits.htm
