Turbo!!! Yay! Yeah, check around the Forced Induction forum, 'cause I've seen several discussions there about what turbo, or what compressor/impeller combinations would work best.
Turbo 101 and
Turbo 201 are good articles on turbo basics. They give a pretty good overview on operation, sizing and other aspects of turbo selection.
Here is another good article on turbos. And
here's shorter article that has some links in it as well. Some of the above are fairly technical, but it never hurts to at least be familiar with what goes on in sizing a turbo for a particular application, even if you buy a kit.

Good luck! Woohoo!
