well if its a b20b ur down on compression so its gonna be hard to squeeze tons of power out of it. if its a b20z u get a bit more compression so its easier. id say a good intake, a jdm itr header, nice flowing cat n exhaust, good intake mani (blox or skunk 2), bigger tb n some crower 403 or 404 cams would do well. ull have to get the valve train for the cams n if u want more compression u can always get a 2 layer head gasket. dont forget the dyno tune. should make good hp n tq numbers. hell u may be able to do it for less than the b20 vtec setup if u do it right. a gsr tranny is also nice for the non vtec b series motors. gl with the build.
