Remember: other than thermal limit (mitigated with oil cooler), gearbox does not really feel power...it is torque limited. You can break it with 100hp turbodiesel or live all day long with highly strung 300hp N/A engine spinning 8000 RPM.
This guy found the limit. And on stock 915, that limit is pretty low.

Well yeah, but In general, the cost of short stroking outweighs the benefit when turbo'ing non turbo engines. With turbo's making torque much lower.. why would you be short stroking it.. once it spools, more revs will just mean it blows off sooner.
short stroking a 3.2 and then turboing it is not going to get you a modern 3.0Turbo24 valve water cooled block with water cooled charge, designed for power, emissions and revs from the factory.
Old engines, you can do one fancy mod
but when you start combining them you better have a steep R&D budget
