Title: how to spot a 3L
Post by: tommycon on 26 March 2008, 21:09:28

hello everyone,,
 i`m buying a 3L engine,,, just occurred to me how will i know its not a 2.5?
 can someone tell me where the number or stamp will be on it ??
i`ve taken a 2.5 out of my calibra but its not at my house to check on.


i bought a 3L elite with the idea of taking the engine out to put in my calibra then sell whats left,,, but as i`ve said before on this site i`m really impressed with the car,, so thats why i`m buying a engine rather than break my elite up.
 great site by the way.
 cheers.
paul

I believe that the 3.0 has the extended plenum on it, so it overhangs the camcover as the 2.5 finishes at the cover :-/

Only has the extended plenum if its from a 98 onwards engine...the earlier 3.0 had the same short plenum and looked the same from the outside...there should be a plate somewhere near the oil filter that will say engine type...should say x30xe (I think it is) on the plate...

On the bell housing flange on the 2-4-6 bank side (right side when viewed from the aux pulley end) you should see the engine number and engine type engraved.

I have a 3.0 engine in a car I'm stripping currently...if your able to help me remove it then you can see it running before you get it...if you have one in mind already then no worries...

the first few digits should tell you if its a 2.5 or a 3.0 or whatever....

I seem to remember that when I bought mine, having two pipes coming out of the exhaust meant it was a 3.0, and one pipe meant it was a 2.5.
