I can't remember the exact name of the article off the top of my head, but they did a junkyard budget turbo hemi build in one of the magazines. Took a junkyard engine and Ebay specials for turbo bits and made something like 600 hp for $3400 (including engine) or something like that. Should have a parts list for what they used to get there. The turbo system was one they actually built for an LS to start with, then adapted to a Ford, then to the Hemi to see how the big three stacked up. Can't say what kind of driveability or longevity it would have, but may give you a direction to look at.
