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.

Turns out the clutch MC is mismatched...I'm seeing mostly 11/16 as the bore....hmm....problem is there isn't anything available in that bore from wilwood or CNC. When I search ebay NOTHING comes up for cars, so the next best thing is probably a 3/4. Maybe I'll try that and if it catches too high it can be changed out pretty cheaply as Mike said. I'll post the results when I get the parts in....it's getting closer now.
