Depends on what you are trying to do.
if all motor then the exhaust system needs to be done. higher compression pistons, Cams, port & polish, light weight flywheel, light weight crank, chipped ecu, bigger injectors, tuning. there is a limit as far as HP with all motor but there is always something to be said about an all motor gsr pushing 280 HP (Most Hp i've seen from an all motor gsr)
If turbo your going to need a bigger catback, A turbo kit, A tunable ecu, and arp rod bolts. you can only push about 10psi with this set-up but with forged rods and pistons you can push more. like i said it all depends on what you are trying to do! With a turbo and forged internals the sky is the limit, on any motor!! personally i am building my gsr be all motor for daily driving and track/time attack uses. I want to get an 02 Lexus IS300 and turbo that car (same motor as the non turbo supra's)!!!
