Heres my deal. I have a nitrous b16a and an aftermarket clutch/pressure plate. The pressure plate is much stronger than stock.

I installed a OE Honda slave cylinder and master cylinder in March as regular maintenance while still having a stock clutch/tranny. I upgraded to a strong pressure plate, flywheel, clutch, etc. in May. This past week, my slave cylinder failed, b/c of an inner leak and also a slight exterior leak. The night before it was shifting fine, then the next morning the inner seal was busted and no pressure could build up at all. When returning the part to honda, they gave me a new one for free. I installed that one, and it leaked even more! The counter guy, who usually knows nothing, was like "is your car sooped up or something, does it have nitrous?" and i obviously lied and said no. I figured he asked the sooped up part b/c then part warranty would be void, but Does nitrous use effect slave cylinder life?

And Does having a stronger pressure plate cause slave cylinders to fail prematurely, or even instantly?

Most important, what are people using for slave cylinders with stronger pressure plates? Will the Tokico unit be better than the OE honda one? Atleast its not rebuilt. Anyone else make an aftermarket slave cylinder?

I have another OE honda slave coming, so i'll see how it does. Maybe i just got a bad batch of slave cylinders, b/c the OE honda ones should be able to hold the pressure, right?

thanks in advance.

also, what about the wilwood clutch slave cylinder? can it fit on honda's? is the quality better?

 

anyone?

 

Don't really know the answer you want, but here's a couple thoughts.

Nitrous or FI or anything at all with the engine has NO influence on the mechanical loads on the slave cylinder. But higher temperatures (turbo??) could be trouble...

A stronger pressure plate is almost the only thing capable of giving stronger mechanical loads to the slave. They're increased in direct proportion to how much stiffer the pedal feels. I would guess that's not enough to make them fail so quickly.

 

well....just installed the new OE honda slave, and it failed as well. the inner seal sprung a leak. the outer seal stayed in tack, unlike the last slave i tried where both the inner and outer busted.

i'm going to buy one from the local parts store and see how it works. i have a tokico one being shipped now as well- they are brand new, not rebuilt.

 

i found the problem today after going through 4 slave cylinders. warranty paid for 3 of them.

the clutch fork developed a crack and bent. it bent far enough that it wasn't stopping the clutch slave cylinder plunger in time, allowing the plunger to over extend- leaking the fluid and not holding full pressure. I bent the fork back and welded it. hopefuly it holds up for a little while.

Are there any aftermarker stronger clutch forks available?

 

all this time you never told us what brand of clutch/pressure plate you have.

This thing's gotta be pretty stubborn for such damage to be done to your clutch system.

 

it was a clutch specialties stage 2 i believe. the pressure plate is pretty damn strong. it doesn't have to be that that strong to bend the fork, if the fork already had an imperfection. over time it could have opened a little crack to a big one.
