With my Integra I added a supercharger to a normally aspirated engine that was already tuned for high performance.  The problem with doing this is that normally aspirated performance engines have a high compression ratio and engines designed for boost have lower compression ratios.

So it is much more efficient to upgrade a turbo on an engine that was originally designed for boost.

I am not familiar with the 4.9L V8, but I have seen some crazy stuff done to that V6 that was in the Grand National.
