You would be working in a small engine bay

I can't answer your question, but if you do, good luck!!!

Even if they both have a 4T60-E, the internal wiring will be different.

A 3400 swap would probably be easier, and have the same HP. But you already have the 3800, I suppose.

A Series 2 3800 supercharged motor was swapped into a Grand Am by a friend of ours out West here. And it wasn't easy.

The fit is VERY tight, and many modifications will be necessary.

PCM swap, wiring harness swap, fuel pump swap?, fuel lines, engine mounts, A/C lines, lets hope the trans match, which they don't because of the year difference. Some use the thermistor inside the trans to monitor trans temps. May have a different final drive ratio also.

I think you'll have to give up on the AC. I don't think there'* room for the compressor.

Ya i know i woudn't have a lot of room to work with the passenger side engine mount and fuel were my first concerns. i don't know if the pumps put out the same gpm. the cooling system was another thought cause i would have to get the hoses just right to clear everything. I hate A/C any way it adds wieght and is in the way plus it is just another thing i would have to covert. If i had the time and money i would but i put some figures together and i can afford it right now so maybe when the engine in my '89 sunbid goes out i will have another good sleeper project idea. i have seen and L67 in a sunbird coupe so i know i can put my NA 3800 in to the engine bay.
