Look around there.
And to answer your question, turbo M30's are much more common than s/c'ed ones, so youll definitely have a great knowledge base to work from.
M30 + turbo = ungodly torque increases
oh yeah, and the most important factor is that to get a s/c you'd have to switch from v- belts to serpentine belts, and quite frankly, its not worth the time effort and money.
If you really really want a s/c'er though, you might as well put a s/c M50 in it, much easier.
In fact, i don't even know of a supercharger for the M30 now that i think about it.
