Hi, I am in need of some help and information. I have a 03 g35 coupe and I am putting an 05 engine out of a 05 coupe. Will there be any problems doing that? Any sensors I need to change or will I need to purchase the 05 ECU? Please help, I would like to have as much info as possible thank you. The 05 engine was taking off of an AT tranny and I am putting it into an 03 6speed tranny, will that be a problem??

 

The 05 AT motor is a non-Revup. It should bolt up fine to your 03 because it is also a non-Revup motor.

 

Okay thank you very much.
