as far as i know it's the same engine, just minus all the emissions stuff. the 03/04 2.3l was PZEV rated (partial zero emissions vehicle). 05+ they made it PZEV in green states and regular everywhere else. its 140 or 144 something right now and im sure without the emissions stuff it would [will] be higher.
