I'm going rear mount on the turbo to keep the heat down under the hood and rear mount allows turbo boost without an intercooler. Less piping, and general ease. It also allows for a simple setup in the event this doesn't work.

Fuel....I considered larger but I figured running 32lb injectors on 13psi of boost (currently) so doubling the boost would be 65lbs, but I actually am going to see if I can squeeze enough room in them to go e85. I'll know after the first tune...

Gut tells me you are going to see more boost then that. Just because it initially compresses to that, doesn't mean your engine is going to suck it in that fast. It will probably build up the way it does for a PD blower.
