I think that depends greatly on the turbo itself, 8psi is different from a larger snail to a smaller one.

Well you mentioned only bolt ons and nothing internally has upgraded, you can take that turbo to some where in the 9psi range. I am sure a little higher boost 12psi with at least some ARP head studs. I am under the impression that boost does not kill motors. High cylinder pressures due to high timing values and greater TQ numbers is the determining factors when it comes to stock internals.

Correct me if I said something erroneously, good luck though.
