damn if youre talkin NA then there are countless possibilties. id start with all the little botl ons like exhaust (get a good one youll need it), headers(get JDM or DC they flow best for the money, but spoon and mugen are the best), intake(i suggest cold air and theyre all pretty much the same. then you start getting to the good stuff. you can swap your pistons to the high compression JDM type R pistons. this will up the power along with the TYPE R cam. but this is for a good evryday driver with good gas mileage. if you want high horsepower you need to get a tuning package or make your own from i would suggest GUDE/BULLFROG performance, TODA, or SPOON. they are all good and you can get over 220hp to the wheels NA with a GS-R motor. do a little research and if you want specifics let me know.
