Thread: 3.3 to 3800 supercharged swap

  1. #1

    Default 3.3 to 3800 supercharged swap

    So the 3.3 3300 in my 1994 cutlass ciera is getting wornout. I got to thinking that most of the parts should be interchangeable trans included. Does anyone have any thoughts on this? would there be anything stopping me from this? hood clearance aside. i would likely try to buy a series 2 3800

    Lots of discussion on here about it. The big question is, do you have a 1994 with a 3100 or a 1993 with a 3300? There isn't a 3300 in 1994. An original 3100 car would be more work, i.e. brackets.

    Hey im looking to do the same thing to my 1990 Century 3300 to a 3800 supercharged. from what i was looking at the most difficult part will be the the harness. i think it might be the same deal for you. almost everything else should be pretty straight forward.

    This guy did the swap you are talking about unfortunately most of the pictures are gone on the first page.

    Someone did a swap on YouTube. The exhaust was a bit tricky and battery relocated some other things
