Anyway, 30 sec. is an approximation. Bottomline from what I've read is the ball bearing GT series turbos don't like being overboosted. Then there's that whole thing on whether or not the center sections are available if you need to rebuild it after a failure (or from overall wear). Some say it is (or soon will be) avialable. Other say you're SOL; and for that kind of cash I'd want parts - our cars love eating parts.
