i have a 2005 titan that engine went bad.... i called 2 nissan dealers before buying a 2008 engine and they said it would work only that the computer needs to be reprogrammed. So i ordered the engine and my mechanic started to do the swap when he came to realize that there are sensors for the timming and stuff that dont match up... so he tryed to contact nissan dealer but they didnt help... if someone could please help me with this it would be great so i dont have to send this engine back and get a 2005-2006 engine..

I know this is an old thread but like many others, doesn't seem to have an end result. I did the same thing, Put a 2007 titan drive train in a 2004. Finishing up the wiring and noticed there wasn't a cam sensor to plug in on rear of motor. What I did was, Extended my sensor connection to the front of my new motor and plugged into the cam sensor on front of the motor. Seems to run great, I guess I have a VVT capable running as a Non_VVT engine.

I know this is an old thread but I wanted to post the easy solution. Last month I installed a 2008 titan VVT motor in my sons 2004 Titan, I extended the original camshaft sensor harness from the rear of the motor to the front of the motor and connected it to the cam sensor on the front of the motor (was on the rear of the 2004). Runs great but I'm guessing were missing out on that extra 10HP somewhere. He has been pulling a trailer with it an no problems. It doesn't throw a check engine code I'm guessing because the ECU isn't able to predict the future invention of the VVT (since it wasn't used then). Hope this helps someone.
