it should be the exact same engine, if the ecu was the only thing changed from '00-'01. The engine bay and wiring harness should be exactly the same too.
In other words, the ECU's not gonna say, "oh hey, this is an '01 engine, I should adjust the rev limiter!" And the engine's not gonna say, "ahhh, my brain's from an '00...must...keep...rev-limit...at 7800!"
