I was browsing some boards, and I came across this site. They looks like they make some pretty killer Turbo systems. They're looking for an LS1/LS6 donor car with forged internals. You get a kit/install/tune all for the price of just parts. I'd do it, but I don't have the money right now. Check it out. They are called Induction Concepts. Mods, please edit the post as found necessary since they're not supporting vendors. I'm not sure what I can or can't post.
