I do find it amusing that in the Porsche community that anyone wanting to turn the power up is instantly not meant for a Porsche, or doesn't understand the refinement of the car or any other of a list of condescending adjectives.

There are lots of things that can be done to a 915 transmission, they are not all alike and there are pros and cons to a lot of the factory pieces, plus a bunch of aftermarket upgrades for one purpose or another.
The 8:31 differential is stronger than the 7:31, the intermediate bearing plates on some versions are weaker than others, there are reinforced differential side cover plates, etc. Bottom line, you can add many thousands of dollars in upgrades to your already expensive rebuild.
Horsepower isn’t generally a problem, it’s the torque. A high horsepower motor that is biased to power in the upper RPM ranges, seldom has enough torque to seriously dent the life of the transmission. Turbocharged engines usually make more torque, so are more of a problem.
The problem that you seem to have with some of our comments is that, on the one hand you want all this horsepower, but on the other hand you don’t want to spend a lot of money to get there. Some of us have been driving these cars our entire lives and what we’re trying to tell you is that those two goals are mutually incompatible. You get a lot more performance for your dollar from other types of cars. A 911 of that era is simply not an inexpensive car to get to the performance levels that you’re asking for.
A 911 is designed for the type of road you don’t have in your area. Even a stock ‘82 can be safely driven at a pace that is not even remotely legal on such roads and can be very challenging. It will never be much when launched from a stoplight. Half the cars out there today will blow your doors off and that’s just a fact.
