I've been running a 915 behind my 300+RWHP 930 engine for over 5 years.
They will last at that power level if you don't abuse them. There are a few folks out there with much higher torque levels also running 915s with modifications. If you go past ~300 ft/bl torque to the rear wheels you need to beef up the 915. It won't cost a fortune if you can do the labor yourself. If you cannot do the labor you are money ahead buying a 930 4spd. With the higher torque level you don't need a 5 spd unless just for personal preference.
