Old 930 tranny we bought for a project car is nowadays fitted into twin-turbocharged 350 cui Ultima car with "a hair less than 1000hp" and works as a charm. Only mod is billiet side plate and upside-down installation. They were regulary fitted in 935's with around 700hp. So as long as durability is concerned, no worries with 930. It shifts like a truck though.

G50/52 is also bullet-proof. It survived 1017hp with billet side plate and oil cooling.

915? Naah...too weak pinion-bearing retainer. Whole case just warps under torque and it's a matter of time when it will grenade. It can be rectified somewhat with billet retainer-plate but cost to install it brings it into realm of G50, and it will still shift bad.
