315 hp.

its the same s54 thats in the e46 m3, but they couldnt run the exhaust as cleanly as they would have liked, so it lost a little power.

the s54 is almost the same motor as the euro s52, which was available between 1996-1999.

what is the difference between them? ECU, catalystor or another ?

yeah that catalystor or cats or something, something that has to do with emissions that restriced the ~10 hp that u.s. got less of from europe... other than that, normal euro spec differences like them using the metric system and such, possibly options/colors and such too, that's as far as i know, but there could be more
