Does anyone have a hydraulic clutch kit for a '72 914 with a side shift?

Thanks!

I have never seen a complete kit. Do a search, their was a member that sold the piece to modify the pedals for the master cylinder. The trans end was always fabricated in different ways.

You'll need to use a 3/4" pull type slave cylinder & 5/8" MC. IIRC, Mark did this on his 914 @Euro911 .

Here's a link to a good thread that shows the pedal bracket and other parts.

This page in my build thread shows how I put in the Hydraulic clutch master cylinder.

And here is the later revision to the clutch master cylinder linkage.

I can't help with the transmission end. The Cayman 6-speed has a hydraulic slave cylinder built into it.

I am curious does it help reduce pedal pressure? I have a stage 3 KEP clutch with my SBC/914 trans and at my age its killing my foot in stop and start traffic.

I have the same issue with the clutch in the 4.0L car. The clutch is VERY heavy. That can be mitigated by making the master cylinder bigger. I am going to try that when the motor goes back into my car.

This is a hydraulic pedal assembly using all Genuine Porsche bits. G50 + 911 parts.

Just fits under the stock pedal board.

Just to clarify the hydraulics

To reduce clutch pedal force, the clutch master cylinder goes to a smaller diameter (but longer stroke) and/or the slave cylinder gets larger.

I tried that. It didn't fit. The clutch master cylinder ran into the body sheet metal.

Agreed, requires a slight clearance bump in the sheetmetal but its all factory. The rest is plug and play.
