well it wont get you 160 but it will make it a bit more enjoyable.
Put on a skunk2 intake manifold. Ive SEEN the gains this can add, and there pretty damned impressive. Next swap the tranny out for a EX/Si tranny. The shorter gears will give you some better acelleration, which should make it a bit more entertaining to drive. Ultimatly boost or a DOHC swap is gonna be only the only way for some real power
