Upgraded clutch slave cylinder?

Postby bartyb on Tue Nov 01, 2011 2:18 pm

So yeah, I got tired of changing my clutch slave every 6 months on the SR coupe with the hard clutch, my pedal pressure is way harder than stock, and the stock slave doesn't like it. It just died again last night.
Is the Nismo option really worth the ~200$? I've read they are basically a re badged stock part.
I've also read that the Z31 might be an upgrade, but without confirming it.

I'm thinking of just modifying a stock part, bore it out on a mill, machine a plunger and bring it to a hydraulic shop to get an HD seal.

Any advice?

Thanks

I'd be curious to see what results you get. Evan and myself change ours every two seasons or so. In fact, mine is due to be changed again pretty soon. Noticed it started leaking again.

Well I spent a lot of time looking at napa's part numbers, and found a few slave cylinders with 13/16" bores, such as the following parts numbers:

37523
37525
37516

The first one might work if I cut the first tab and tig it on the other side. It looks similar to the skyline slave cylinders.

But what I think I'll do is just bore out my busted slave cylinder to 13/16 since only the seal failed, and use the internals of this one. Total cost, less than 20$. I would really appreciate a lighter pedal feel, and even more not having to change something that often. I also spoke with a hydraulic shop, and they can provide me with a seal as well, which will be cheaper than 20$, but then I would have to also machine a plunger.

I'll keep you posted.
