Need help with 735i

I am currently SERIOUSLY considering purchasing a 1992 735i. I kind of have my heart set on turning it in to a pretty nice performance vehicle (more so than it already is). Currently, I have working knowledge of the capabilities of Asian vehicles, and performance enhancements, and of course domestic (north american) vehicles. My big question is how will the german engineered inline 6 of the BMW 735i take either a super or a turbo. Personally, I would rather put a supercharger on it, however, I would be willing to use a turbo. I realise that 209 Cu.I. seems a little small to put a supercharger on, but I'm just really set. Possibly because I want a smooth intake built in to the hood. I would really appreciate any information. Only on the actually super of turbo though, I've pretty much figured out the other major aspects.

DINAN and Callaway Turbo names come to mind but at what $$ ? ? might be better to find an E32 740i
