hahha ok sorrie damn didnt know maybe some one would answer it -_-

just woundering wat i would have to do to my s13 black top to boost it over 310 hp cuz i just got it swaped into my s14 ?

get a bigger turbo...stock turbo is only good for 15-16 PSI i think and at that PSI i think it makes around 220-225 at the wheels.

*Edit* also if you do not have it..new exhaust with 80mm piping, clutch/flywheel, upgrade fuel system, cams, cam gears, lightweight pullies, converting to electric fans might help a lil too
