I believe the weak point is in the case not being able to keep everything together with high HP engines.
Factory writing from early turbo development indicated the 4speed was necessary as the 915 could not be modified for the Torque/Hp capabilities of the turbo motor. Keep in mind they built the 930 project to compete in group 4 and at that time the 3.0 liter turbo in group 4 development was getting to 500HP. The 930 4 speed is good for well over 700HP using a trans oil cooler for extended track time. I personally would go to different R&P for reasons outlined in my last post or gear changes in the 930 trans as it will cause no other expensive alterations. If you can stay away from more HP mods a 915 with some upgrades as RarlyL8 alluded to should work as I think he has modified his 915.
