homemade turbo

[6Speed]

My buddy has a stock turbo from his eclipse that I can probably get for next to nothing. He can also help me get an intercooler (have no idea where I'd mount the intercooler). Anyway, my parent's house has a lift in the basement, and I have access to a welder and plasma cutter. I can weld decently, but I have a friend who welds for a living, and I'm sure he would help me. I think I'm going to buy the turbo header from cbperformance.com, and see if I can fab up the rest of the ductwork myself. I think I can build it for a lot cheaper than the 3000 dollars that the hideaway kit costs. One thing I'm curious about though -- I know how fuel injected turbo cars add fuel with boost, but how does a carburated car add fuel per boost?

Has anyone else attempted this?
