first of all, "psi" means NOTHING when talking about how much you can safely run, it's not about the pressure, it's about the quantity of air.. in order to correctly guage what kind of boost you can run we'd have to know what kind of turbo/s/c you're looking at... someone could tell you something like "yea you can safely run 6 psi on tha tmotor" but if theyr'e assuming a t-3 turbo, and you have a freakin' t-76 you'll blow your motor sky high... as far as supporting mods, if you go s/c, get headers.. if turbo, they'll be in the kit... and for the rear end, i say get an 8.8 it'll be much better in the long run, because if you spend th emoney on a t-lock for your 7.5, you could have already bought a used 8.8......
