hm. I took the much less engineered approach of hooking up my Delorean clutch master cylinder to the Porsche clutch slave cylinder on my '95 G50 6-speed transaxle. It worked, though the Delorean clutch pedal was very hard to press. This translates into the fact that the master pushes more than enough fluid to work the (g50) porsche slave cylinder. I ended up moving the clutch linkage on the clutch pedal in order to give the driver more mechanical advantage by shortening the throw of the master cylinder over the range of the clutch pedal. The pedal is now in an equilibrium where the master cylinder has just enough throw to fully engage and fully disengage the clutch.
