what will it take to fit a 1990 Buick Regal 3.8L engine into a 2003 Buick Century Custom that had a 3.1L engine
2 Answers
The engine will go into the Century without a lot of problems, maybe motor mount changes, the real problem is the electronics. in 1990 the electronic interface was different than the 2003. If you used the 1990 ECM it would not talk to the 2003 BCM, If you have an advanced electrical engineering degree, it might be a snap.
