I've done some looking around and there is a couple of options.

The best solution would be to use the computer and engine from a turbo
car.  That would allow you to utilize the computer control of the
ignition and fuel mapping.  

You could put an S/C onto a NA engine, but it would require some
definite custom fabrication of plumbing, plus you would have some
definite issues with providing enough fuel through the NA's FI system. 
I have corresponded with some of our q-listers who are more experienced
in forced induction matters than I am and one idea that came up was to
replace the stock fuel distributor with one from a turbo car. 
Apparently, (if I'm remembering correctly) it should be almost a
straight swap.

Depending on the boost level and partictular S/C you might not even need
to use an intercooler.  And a dump valve to release pressure when you
snap the throttle shut seems to be a definite must.

HTH,

Gary
