How much of a technical problem would it be to put a 2008 used 350z motor into a 2006 350z.
Fitment?
Ecu ?

 

ecu, wiring harness, i believe the engine is a little wider and definitely taller, so you would need a new hood, the radiator support in your car isn't setup to handle the dual intakes, not sure if the de trans would work on the hr motor.....

i don't think you can do it cheaply, could it be done.... with enough time money and cussing i am sure it could be

 

Cheaper and much easier to sell the 06 and buy an 08.

 

DKMura did it in his track car ... far far far not worth it!

 

Really only worth it if you have a built race chassis and you don't want to start over building a new chassis up to spec ( cage, sound deadning removal , wire harness removal)
