With the caveat that this is based on a a 3.2, and the assumption the 2.7 and 3.2 were updated the same year, the 2003 has a different Variocam system than the 2002 and earlier. When I pulled my 2003 apart I was stunned to find the Variocam actuators missing. They were relocated from between the camshafts to a unit in the head that uses oil pressure to change the timing. I was working from a 2002 and earlier manual. That is where 3 chain versus 5 chain engine descriptions come from. That is also where the comment on the heads and timing system comes from. I believe the DME also was updated to accommodate the improved Variocams.

So definitive (or infinitive, I never was good at English), not so much. Is it a straight drop in? Not likely.

My 2 cents.
