Acutally, he would have an M52 if his was a coupe. That's what I wasn't sure about.
The M50 was the 6 cylinder engine in the OBD I cars through 1995, coupe, sedan, convertible. 2.5 Liters. The M52 is the 2.8 liter 6, I think through 1999. I believe the later 2.5 liter engine was the M54, not sure about that. I'm sure the 4 speed has a different transmission controller than the 5 speed. I'm not sure they are both compatible with the engine ECU. That would be what I'm concerned about. If they can't talk to each other how would the trans work?
