91 sunbird 3.1 v6

will the 91 v6 fit in the 90? im looking at doing a motor swap. I have the 2.0 4 cyl. in there now....Any thoughts?

You need the engine wire harness and the ECM.

Bolt in , nothing changed . You need what Mel mentioned above + the V6 trans as the 4 cylinder trans has a different bolt pattern. Cavalier V6 with trans will work also. Best to get another car and swap everything over.
