from personal experience, I've run the turbo. It worked fine. I was running it at 15psi and it was great. When the vacuum line tore is when I killed it by unknowingly running it at 30+psi (note: pay attention to your boost gauge). I swapped it out for the godspeed 60-1. Broxma ran a godspeed gt35 for over a year at 17+psi, and netted 362awhp at 18psi with a 5" crack on the intake manifold. That turbo still spins like the day it was received. I have yet to have a bad experience with them. Just another side of the story.
TL;DR: Do the proper maintenance and use the proper oil and it will be fine. Personal experience, not some "That guy said"
