Will 1994 cavalier 2.2 fit in 1994 sunbird 2.0?

They are the same car....for the most part. There may be some differences in engine mount style or location. If you have the 2.0 to pull parts from it would help. The biggest problem I could see would be the ECM. I'm not sure if the wiring is the same or not. At the very least you would need the PROM from the Cavalier.
