Gotta love the parts commonality. This is the pressure plate I’ll be using on the Turbo, and it’s the same as used on 911s with the 915 gearbox from 1972-1987, that the 931's G31 gearbox shares much from. Not only is it identical, it’s also got twice the clamping force of a regular 931 pressure plate, should someone (not me), wanna up the power. Mind you, even though the pistons set the compression ratio, the 931 engine has the same internals as the Carrera GT/GTS.
Now, if you’re wondering why I picked this pressure plate without planning to make more power, that’s because this only costs $210; whereas a “proper” 931 plate is usually $300+, and the highest I saw is $350!
Win-win, again! I’ve now got everything needed to put the car back together, I just need to send the flywheel off to be machined and have a new pilot bearing pressed in. And they say the 924 “isn’t a real Porsche”, HA!
