There are 2 slave cylinders on the "part numbers we all need to know" thread
Slave Cylinder (Green, 20.64mm) MD733227
Slave Cylinder (Pink, 19mm) - MD733623
Not sure which one to purchase.

Pink if you can get it.

Small pink is the ticket to a good feeling pedal pump.

Green is vr4 & nla. Pink is dsm & available.

So is the pink not compatible G? I just want to know if I can buy either one without running into any problems.

It's physically compatible but not designed to work with the pressures of the vr4 master.

So if I were to install the master cylinder ( MB555133) compatible with the pink slave cylinder I'd be okay correct?

Yes. It is claimed that the slave with the smaller bore pushes the rod out slightly more to help with clutch disengament.

Is there anything specific I should know about when replacing these parts?

Once you install it, bleed the crap out it.

LOL guess thats the obvious. Thanks for all the help guys.

Quoting G:

This is a completely inaccurate statement. CAPS shows application for both the pink and green part numbers for GVR4. AS for the clutch masters, the casting and bore are identical between 1g and GVR4. The only difference is the reservoir size.

Quoting KiNgMaRtY:
Yes. It is claimed that the slave with the smaller bore pushes the rod out slightly more to help with clutch disengament.



There is no claiming anything here. It is simple mechanics. Same fluid displacement at the master cylinder will yield more piston travel at the slave for a smaller diameter piston (displaced volume must remain constant).

^ truth. I always try to find the pink (smaller one) for any clutch install, but especially if it's an aftermarket heavier clutch.

91 GVR4s had a green slave, the 92s got the pink. Same master in each car, explain to me how it's not designed to work with a pink slave.

It's just G talking out of his ass again. Nothing new... Carry on.

Maybe he needs to control his fans. /ubbthreads/images/graemlins/grin.gif

Ha! When i look in caps for a 92' it calls for the green. Not the pink. /ubbthreads/images/graemlins/uhh.gif

Which is superseded by the pink.....

Cause my 92 had a stock pink in it. Even had all the service records from new and there was no replacing of the slave.......
