Here is my dillema...I have a primera engine, but I never swapped the intake manifolds, so...no EGR, now I heard from some people that the car wont run as good without the EGR, and others said it doesn't really matter. I have had the engine in my car for about a year now, and I feel it runs good, but I am curious if it actually does run better with a USDM manifold.
I am guessing all the EGR stuff is somehow programmed in the ECU, and would getting an ECU with a program for no EGR system make any difference?
Any help is appreciated.
