it's not so much about the boost in those cases, its the torque. with the correct timing adjustments our cars can run 12psi on 93 with stock compression. I would just advise staying in the range of 450-500whp/400-440tq, don't get greedy.
Find a good tuner, keep power within limits of stock internals, reduce boost when it gets colder out (cold weather == 30-50+hp). for the sake of your bearings, keep oil temps low (< 230), let the car warm up properly (> 160), change oil regularly. your engine should hold up for quite awhile.
with that said, anything can happen. be prepared to build. my engine just got finished at the machine shop, time for assembly
