4V's are so awesome. Spark plug changes will be a breeze, and no more spitting plugs. Not to mention you can rev the **** outta them.
The only obstacles I've heard with installing 4v engines are:
[*]Exhaust manifold fitment (obviously since the heads are different) hopefully you have the stockers?[*]ECM on the NAVI was for the 4r100 tranny. Not sure which on you have.[*]Injectors will require ev1 to ev6 adapters[*]COPS will have to be reversed
I have the stock exhaust manifolds. Might throw shortys on it though just because I want to replace the studs and such while the motor is out and ready.
I have 4r70w so I know there will be some issues with the computer.
Thanks for injector tip!!
Explain this COP reversed thing...
