this question seems like too broad. but i do need some detials about building my engin.
92 gsr, so far, this car got:115,000miles. t4 turbo,delta gate, i/c,votech FPR, upgraded fule pump, RC310 injectors, S-afc,turboxs mannul boost contorler.
the question is what do i need to do to run 12psi safely. i know this has to do with reinforce the engin, so what i need to prepare. i expect some detail info, such as compression ratio of the new pistons, which brand is more cost effective than other brand......
thanks
