i have an my 02 sti running approx 330 bhp,does anyone know what the max bhp and torque i can push it with standard internals,also what are the internals like,is any of it forged or strenghened and would it cope with mods such as ported headers,bigger turbo,bigger injectors,it already has full decat,walbro fuelpump,ngk 7 plugs,k and n panel filter,standard vf 35 turbo,and remap from simon at jgm.just want to know what other mods and power can be acheived SAFELY in the future,thankyou all

 

plenty of folks running up to 400ft lb torque and 400 - 450bhp, should cope with this sort of power if looked after well.
