    Swapping Buick Century Custom 3.1 for Supercharged 3.8?

    Was pondering a swap for a supercharged 3.8 into my 96 Buick Century when I retire it from daily driver status. Was wondering if I could get some advice on what to look for. What series 3.8 to use for simplest transfer, and what all I'd need to change/ get from the donor vehicle. Thanks in advance!

    I've given that swap a good deal of thought. A far easier solution, and perhaps no more costly, would be to find a clean GS and swap the trim. I always thought a sleeper Century with the SC mill would be the cat's meow. But trim swaps are far simpler than engine/trannie swaps.

    That's definitely true. Maybe I'll go that route then. I'll have to see down the line what I'm willing to do and how it pans out. I have access to a mechanic garage and all that entails though through family as well, so maybe the extra effort would be a good learning experience too. The century is in beautiful condition and low mileage to boot, so I was hoping to pick up a new daily driver in the near future and keep it nice and minty for whatever I choose to do with it down the line

    the 3.1L and 3.8L are totally different engines and you would need pretty much everything under the hood
    if the car you have is nice and/or sentimental I would recommend buying a WHOLE DONOR car as close to model and year as you can find
    also 96 is the switch over year for OBD II engine management and you WILL want to make sure the donor as also the same - I assume yours IS OBD II so the donor would have to be 96 or newer

    these sort of projects are WAY easier AND cheaper in the end if you get the whole car as otherwise you get "nickel and dimed" buying the SMALL parts
