So here's my current situation. I have an 2004 G35 Coupe A/T. Production date 10/03. From what I understand an 05 or 06 engine should work as long as it's non-revup. I got a used engine from a 2006 G35 Sedan A/T for cheap. My question is what all will need to be transferred from the old motor to the new one? Such as sensors, injectors, intake, throttle body, etc. I could really use some help with someone more experienced, so I can save myself some time and frustration lol

 

Anybody?

 

The 2006 G35 Sedan A/T engine should be the same as your 2004 G35 Coupe A/T.

03-04 are all DE non rev
05-06 are DE non rev (AT) and DE rev up (6MT)

That is for all g35 coupe/sedan and 350z.

 

So even though the fuel injectors have different part numbers between years, they're still compatible? My question is mostly about the sensors, and other supporting electrical systems
