CAN I SWAP IT AND WILL IT WORK !!WILL THERE BE VERY MANY CHANGES TO MAKE IT WORK??? JUST A BROKE GUY THAT NEEDS TO KEEP THE COST DOWN AND NOT GET IN OVER MY HEAD!! TY RON.
Answer: Yes, they are the exact same engine and you could swap them easily. There shouldn't be any changes needed at all, they have all the same sensors, so you can use the existing wiring harness and computer. There might be some nominal odds and ends that are different between the body styles, but mechanically they are the same.
Sunfire Motor Swap
1999 Pontiac Sunfire Engine Size : 4 cylinder 2.2L in-line.
Question : i have a 99 Sunfire and a 2002 Cavalier. my wife ended up wrecking the cavalier (which has the exact same motor) and the insurance company will more than likely total it out. is ti possible to swap the motors and will the mileage have any effect on the transmission?
Answer: It is possible to swap the engines, and is actually a pretty easy swap to do. The transmission should not be affected either way, unless it already has problems. If you do the swap, make sure all the engine sensors are the same, as they change slightly from year to year. Usually it will be OK, and just fit right in. You should use as many original parts from the Pontiac Sunfire as possible, like the intake, exhaust manifold, etc, which will ease the change over.
Sunfire Motor In Impala
Question: Would a 2004 Pontiac Sunfire motor fit into a 2003 Chevy Impala?
Answer: Yes, if it is the same engine size it will fit. You would have to do some modification though. The power steering hose routing, engine mounts, A/C pipes, engine sensor harness, etc.
