If you beat on most things withs 500+ hp, things generally start to break. You can't really expect to have a bullet proof driveline in a car this small. The transmission that I think you are looking for is the Getrag 282 which came in the Fiero GT's and several other cars. SLIGHTLY (if at all) stronger is a Getrag 284 which is harder to find and takes more modifications to make fit. (I believe including different length axles as well as different stubshafts) If you end up supercharging it, getting around 550-600HP, expect things to break, especially if you plan to beat on it all the time. Agreeing with Ragtop, go with the porsche tranny. Its going to take a lot more engineering/money to get it to fit, but will be better suited for the constant abuse. Let us know how it goes and good luck.
