Theoretically you can turbo any car. It's a matter of getting the proper exhaust/intake manifolds, building your engine internals to be able to handle boost, oil lines, pipe, and ofcourse, the turbo itself. There's no one turbo built for any specific engine. Try www.f-bodyhideout.com
and see if anyone else has turbo'd their 3.8L. They could give you a more definate list of parts/work involved you'll need to know.
