they didnt come stock with any us vehicles. we only got the sr20de. anyways, there are a few se-r guys pushing close to and over 200hp na with these engines. cams from a sr16ve do a lot, as does a header from some japanese company i cant spell. awesome engines, but dont mistaken them for anything vtec. the technology is completely different. the sr20de's 5speed bolts right up.
www.sr20deforum.com has a whole forum for these engines and a great faq on them.
