The G50.52 slave has more total stroke by approximately 1/2 inch, if I'm recalling things correctly.
The MPL as installed wouldn't extend far enough to allow the pressure plate to fully disengage. I had a horrible dragging sound with the clutch pushed in.
If it was biased to the retracted position it would be a simple matter to make a spacer for the slave but that isn't the case
There's an urban legend that a 996 Turbo GT2 slave and a spacer would work but I bought one to study and it has even less stroke.

 

Was there resolution to topics discussed in this thread?

Brandon, have you solved? .... Does your pedal now return all the way to the top?

 

Resolution: Don't be like Stefan and I; get the appropriate pressure plate strength for the torque your engine's making.

 

Don't let Woke America know we call our parts master and Slave cylinders. I already had to rename our bedroom.

 

It is resolved.

I removed the pedal assembly and cleaned up. Replaced Master. Replaced Slave. Replaced the flex line with a braided line from FVD. Bled. All is good - but don't know what actually fixed it lol. But I'm ok with that. I have Sachs Sport clutch I think.

On another note - another local 964T had an engine rebuild and used that MPL slave - it works great on his car.
