Ok I had a chance to compare the exhaust manifold, looks identical.
Intake is obviously different.
From what I can tell at this point, the newer IAC is a six wire, whereas mine is a 3 wire.
I am curious if there are any major disparities between the injectors:
Lb/Hr, Impedance, (I believe the connector style is different).
Also, are any disparities between the cam/crank reluctor wheels and sensors in these two engines. I have heard that there are but the sensor bosses are identical and I'm curious what the differences are.
I'd prefer to keep my MAF setup and not swap over to the EJ253 MAP setup if possible.
