2001 Saturn SC2 Question: engine swaps with different years are they compatible
Answer #1patrick mannion from Greg Solow's Engine Room, March 28, 2011, 19:16Master
You can't swap a single over head cam with a double over head cam the electrics and exhaust, intake ect..... will all be different. With newer cars even small changes from year to year make it hard to change out an engine with another engine and the computer monitors things so closely you have got to make sure everything is compatible. Wrecking yards usually are pretty good at knowing what will swap but then again they just want to sell you an engine. I would call an engine rebuilding company like ATK or even call several re-builders and ask them..Perhaps post your question to Saturn specific forums maybe someone in the Saturn group has swapped out an engine and knows what will work.
