Several months ago, while driving, my clutch pedal went flat. I got out, looked under my car, saw the clutch fork hanging funny (I had broken the fork pivot ball), and my slave cylinder pin was overextended to the point where it was being held on by only the slave boot. My transmission shop didn't believe the slave cylinder could still be used but I refused to buy a new one. I got the pivot ball replaced, pushed the slave cylinder pin back in, bled the clutch line, and it's been working flawlessly ever since. Nismo slaves might be kinda $$$ but they seem to be bulletproof. Try thenismoshop.com. According to their website, the RB20 uses the same cylinder as the RB25??? I've always thought the RB20 used a smaller cylinder. Might have to check the RB FAQs on that one.
Holy shit thank you! I do have a HD clutch so the seals likely can't handle it. Other than that it's all gucci until i start kickin the clutch. And just checked the nismoshop and it seems they dont have one for the rwd tranny. I know nismo did make them though, so I'll keep searching. Thanks bro I will update with results when I upgrade.
