just to stir the pot a little. I'm going Pishta's style but.....
if I'm gonna be turbo'ing mine I need an power steering AND aftermarket 508 sanden A/C clearance too! . if you can make that happen I'm in!
With the clearance issues you might have in positioning a turbo to allow for power steering AND an A/C compressor and all the plumbing for those systems, a rear-mount turbo back by the back bumper might be the best answer for you. There would be a lot of cold-side fabrication, for sure, but I have heard that those systems work well, and, doing it that way would free up a LOT of room under the hood.
