Hey all,

I'm at the point where the hydraulic clutch setup needs to be mapped out for my Subie conversion. The donor trans is from a 2006 WRX with a 13/16 slave cylinder. Initial reaction is to buy a 13/16 generic (wildwood or CNC) master cylinder so they match and give a “factory” clutch feel but after some internet searches it seems that pedal travel is also a factor and might mean a different size would be better. I’ve seen some GREAT hydraulic clutch threads but could not find one for the Subie trans setup.

I’d assume the pedal throw is probably similar but could be wrong. BIGKAT is using a 3/4 and mentioned he might rather have a 5/8. His trans likely has a ¾ slave.

Any insight or thoughts on this? You don't have to be right! Brainstorming is great too. (IMG:style_emoticons/default/biggrin.gif)

If it were me, I would probably crawl under a working Subaru and measure the amount of actual movement of the slave at full pedal stroke and try to duplicate that movement on the 914....it's the safe way and I hate to do things twice....I'm willing to bet that the 914 pedal (at your foot) moves much more than the Subaru pedal so keep that in mind so the actuation is not painstakingly slow.

All this said, I would try to stick to a generic brand M/C like a CNC so that if you decide later to change sizes it's a simple and cheap change (they look identical on the outside) and you don't have to remake all the brackets.

Good luck
