Since no one has done it yet that I know of (though area 51 has a supercharged one?), there's one pretty safe way to do it; basically replace a lot of the internal part of the motor. This would mean the pistons, rods, and valve springs. I don't know if anything else needs replacing yet. I guess if you don't go over the stock rev limit, the stock valve springs would be okay; you'd have to worry about hitting it a lot with a turbo though, especially in the first 2 gears. You'll also probably need to sleeve the block. For the engine managment, since JWT doesn't have a program out, the safe bet would be a stand alone system. You could get away with those black boxes but I wouldn't try!
Well, there's a first for everything so they will be a first turbo QR someday.
