I have an 04 g35 coupe 6mt. My engine is in very bad condition, so im looking to replace it. I have been searching for weeks and cant find any that are trust worthy for my year. I have found plenty of great quality engines after my model year. Can I use engines made after my model year in my G?? Please help! If you find any great quality, low mile(preferably under 80k), and from a trustyworthy distributer. Please tell me!!

 

i would think you could use any 03-07 engine but I'm not 100% sure

 

You can use an engine after your model year as long as its from an automatic. You have a "non-rev" DE motor. These were still used it 05-07 auto coupes and 05/6 auto sedans.

You can NOT use a rev-up (05-07 6mt coupes and 05/6 6mt seadans) or HR motor (07/8 sedans).
