How much power are you looking for? You can buy a non IC'd turbo kit that will bolt up to a stock engine without any mods. There really isn't any words to describe the feel of a turbo v.s. a s/c. Plus if you are looking for serious hp out of your 3800 then I would recommend turbo. The factory s/c on these car will only get you so far. So give us some more info on what you are looking for out of your car, and then go from there.
