30psi 762.3whp
Boost pressure has very little to do with max hp and engine limits. A t25 pushing 18psi could kill that motor while making low power. But a 6262 on 18psi tuned could make 350+ hp and not hurt the motor one bit.
My point is we need more details of what you plan to run and what your goals are. I also think you should search this forum over and do some more reading. Lots of good info on turboing fwd sr20s on here. Good luck.
