My previous car was an rsx-s and i lived over in that forum. if you would like any info please ask me.

as far as basic specs, hondata #4, CAI, and exhaust will put you around 180 WHP. The only daily driven 350 WHP type s's are those with turbo and they bump up the boost to race. The jackson supercharger for the s puts down around 250 whp.

the also make a toda kit, which is cams ontop of raceheader and that throws down around 220 - 230.

i had exhaust and intake on mine and it was about 10 HP more than stock i'd estimate.
