I'm doing a 4G63 head swap on a 1991 Mighty Max using the head, ECU and wiring harness from a 1995 Eclipse. The ECU has an ECMLink EPROM. Do I need a vehicle speed sensor to be able to tune the ECU properly? I'm using the original 5 speed manual trans.

I had a theory that adjusting the fuel pressure regulator and trying to start may tell me if it's either the fuel pump bad, or the fuel pressure regulator bad. Adjusting the fuel pressure regulator did not help at all though so I decided to try something else.What is the fuel pressure output...

This might be an easy question to answer but I was curious if theres any difference between the 4g63’s in the 1g and 2g or are they the same? And if there are and differences what would they be?- James

I was debating whether or not to start a thread over this, however, I am curious if these specific pistons with the type of damage they have are able to be saved. I figure this will offer a future resource on top of what is already out there to those looking into these pistons or if someone...
