Are there any members that have converted their larger engined flat 6 or V8 conversion cars to a hydraulic clutch? I tried a search, but couldn't find too much information. My problem is a very bad left knee that is not getting better (at least until I get a knee replacement done), and a very stiff clutch pedal on my 915 gearbox. Mine is one of the early ones without the spring assist, so it is not easy to hold the clutch in without seeing stars!

Does the hydraulic conversion make the clutch effort any easier? My factory six has much lighter clutch actuation , but I need to do something to lighten the force needed to actuate the clutch in my conversion car. If someone has the correct bores and stokes needed for the hydraulic conversion (or perhaps the actual parts to use), that would be very helpful.

I'm hoping that someone has gone down this road and can give me some feedback! Thanks in advance for any advice.

The clutch on my 915 wevo is piece o' cake. I got a '75 911 pedal cluster and the omega contraption in back. Bit of a pita and a puzzle setting it up at first. The '75 and '76 911 pedal clusters have a spring that forces the clutch pedal down instead of up. I wonder why it wouldn't be possible to update your set up. On the other hand, I've heard of the early style 915 "long arm" wasn't that heavy either. Is it just your knee?

I've been told that you have to match front and back. Meaning, the throw of the pedal lever has to be matched with with whatever actuation was used on the gearbox. If you got it wrong your pedal travel will be short, but the effort high. You can get it wrong the other way such that the pedal travel is long and light, but the clutch may not disengage.
