1994 Saturn SL2 Engine replacement

No u can't there differnt engine wire harness under hood fuse boxes differnt computers differnt transmissions.U will also run into problems if u have to get the car smogged because it came with a twin cam engine.U will also be going from a 124 horse power engine to a 100 horse power engine with the single cam multiport.I would much rather have the twin cam engine. Also those single cam engine heads crack on quite a few of them and flood oil into the cooling system what a mess there. Let me know if u have anymore questions.
