Well their are thousands of Turbo trannys sitting behind Tacoma 3.4L Supercharged V6s. I would estimate their HP to be near what your looking for, but your engine will definitely have more torque.
But we have never ever seen a blown up Turbo Tranny, ever. We are still waiting to see a wasted one. Even all of the cores that Marlin buys from junk yards to rebuild, he has never seen one bad. This isnt to say that they are bulletproof, but what Marlin always likes to say is "BRING IT AWN! YOUVE GOT A HIGH POWER ENGINE, BRING IT AWN!!" quoted from Marlin there..
Marlin did tell me once that the whimpiest piece in a stock R-tranny is a steel center piece that supports a couple bearings. He's never seen one fail, but cores that he received with high mileage he can see some wear on those pieces, so on every rebuild he has ever done he takes that stock steel piece and modifies it to increase its life expectancy. Sounds like some top secret thing he does, but I guess that's why his trannys are top notch in the world.
