Usually anything with over 375 ft lbs of torque on a 2.5 suby is pushing your luck with awd on a suby on stock gears. Course thats with about 28-32 wide inches of rubber contact patch with street tires. The story is the case may try to spread inbetween the shafts with big torque and or the input or main shaft flexes. What I've read is the true strength on a tranny is the distance between the shafts as it allows for bigger diameter gears and therefore stronger gears. Probably the audi is a better choice for the good v8's. The suby 2.5 doesn't have the low end torque like a v8 so in a suby the torque builds in the higher rpms and the car is already moving.
