I'm curious i have a friend's 2005 350z AT he was looking to install a 2004 350z manual engine using the automatic transmission is it possible of some sort wiring all the same just bell houseing don't meet with engine?

 

For one. Wrong section.

Second I think what your asking is if yOu can motor swap a 05 to a 04 with different trans's.. Yes but you will probably need a ECU and some other smaller bite but yes it should accept it with out issue from a 05 to 04.
