Slave cylinder...Nismo?

[DataXUnknown]

Okay I think this may be the last god damn problem on my list that popped up. After the fuel line busting, replaced that with high pressure lines, and the clutch installation (dropped that down and the TOB was installed wrong) After all is done, the slave cylinder takes a shit and the pedal just drops to the floor on my way home today...:aw:

http://www.optionimports.com/niclslcy8924.html
So what I am asking is, does it make a big difference if I get the nismo one? They are really expensive...I really just want a stock replacement. I would also have to buy the pivot seperately...

Another question about the clutch, it makes a sqeeling (sp*) noise when I step on the clutch pedal. It sounds like crickets when the clutch pedal is pushed down, but when I accelerate to a certain RPM it goes away. The clutch has a lot of vibration in the pedal and shakes the whole car some times. I thought that was just because it needs to be worn in, am I incorrect?
:-/ The pressure plate has a small bit of damage on the spindles where it hits the TOB from the incorrect installation, half of the spindles have small indentations where the TOB has grinded into them a bit.

Thanks in advance

Z31 turbo is supposedly the same piece for less money. If not, OE is fine, the Nismo piece is way over priced.

[sblack13]

just get a stock...
they make the pedal have a lighter feel
totally useless if you don't have a stiff clutch
I am using nismo personally (On Exedy Triple Plate), i love it.
Great feel to what used be a brutal clutch feel (i know i know)
But I like it! just get OEM if you are having a hard time deciding.

Friend used nismo with an almost stock clutch
and we could't get enough pressure to even have the car drivable.

[DataXUnknown]

Thanks for the feedback, going for a stock slave cylinder definetly then.

Now just have vibration in the clutch pedal and squealing noise (like crickets) in the tranny. Could it be just from a slightly damaged pressure plate?

[GSXRJJordan]

Squealing could be TOB (on a warped pressure plate), or noisy fluid. Does the sound come/go as you press the clutch?

[CKAMC]

if you run a single disk then getting a new OEM is better

dual or tripple disk I would say nismo/z31 is a good idea

slave will eventually die again, but not for another couple of years depending on how much abuse you put it thru, nismo to me doesn't make it much stronger for abuse, just makes the pedal feel better/nicer

[fliprayzin240sx]

Get OEM from dealer, not that Autozone BS crap...

[sblack13]

true even if they give you lifetime warranty
they still break quickly

clutch pedal that does'nt pop back up= no fun.

[DataXUnknown]

Squealing could be TOB (on a warped pressure plate), or noisy fluid. Does the sound come/go as you press the clutch?

Yeah, the sound only comes and goes when I push in the clutch pedal and hold it. If the TOB is warped, is that still ok to drive on?

[SleeperSx]

I wouldn't buy a Nismo Slave Even with a Stiff Clutch. I have a Stage 4 Cusco Exedy Twin Plate, (Stiffest clutch you can buy) I blew my stock RB slave. ALMOST bought a Nismo, Was a Click Away when I found a NAPA Slave, (Same as the Nismo Exactly with out the Sticker) For 16$ Vs nismo 250$+ To me you would be paying for Shit!!! Ill Buy 50 of the 16$ ones before Ill buy a Nismo one. I have been running mine for 6 months now from Napa and never had a problem. Only mod I had to do was drill the bolt holes out a little more.

So just buy an OEM one. The nismo really doesn't make a difference unless you just like to name your parts.

[sblack13]

^have you ever drove a car with a nismo on it?
its been stated do not use anything but nismo or oem.
autozone crap will fail.

[flip3d]

Get an Exedy OEM replacement clutch. Comes with pilot bearing, TOB, and clutch tool.

Also, get a Nismo clutch fork pivot and just an OEM slave cyl.

Are you using the rubber clutch lines? Get the SS braided line. It's definitely worth it.

Replace those and you wont have to worry about your trans again.

~$150 for exedy clutch kit
~$40 for clutch line
~$40 for nismo pivot
~$40 for slave cyl.

so around $300 DIY

Ya I have drove one, Didn't really seem like much of a difference, Maybe a Softer pedal.

I don't buy AutoZone Crap, cause thats what it is. But I will Buy NAPA, Stuff. Really good parts there.

I also Have SS Clutch lines. So it makes mine a little softer but I still won't drive my car in traffic. It just a pain in the ass. So if your looking for a Street ride, I don't recommend a Stage 4 clutch, But I mostly do track racing anyways, So it will hold up good there.

[slider2828]

Exedy stuff sucks in terms of the TOB... MY new exedy TOB started making noise, I rather just get a z32 TOB, works much better. As per slave cylinder, I usually get the one from PDM-Racing, its like 12 bux and it works really well.

Although I bought a nismo slave (I'm a name brand whore, plus, who doesn't love Nismo?) I have to aggree that Napa really has good quality parts. Compared to Checker's, etc.

[GTChampion]

I was just about to buy the nismo one too then i went to napa and got the same one for 29$ for what the part is ...the nismo one is not worth it ide say.

[DataXUnknown]

I went with a stock replacement from Napa, it works perfectly no complaints at all. Just found out though that my input shaft sleeve has been ripped clean off...probably due to improper installation.

I definetly made up my mind that the nismo slave cylinder just wasen't worth paying all that money. I bought it from Napa for $18. And I am using the rubber clutch lines, I was planning to upgrade to the steel lines but I have too many things going on at once...I will save that for another day.

Thanks for all your input guys. +1 for Napa!

me and my buddy work for an auto parts store here in nor-cal, one night when it was really slow we decided to compare a bunch of things that we had "upgraded" or heard of to see if everything was true. our findings were that all nissan slaves for rear wheel drive cars are exactly the same (z31, z32, s13, s14) only with varying prices, we physically took them all apart and mic'ed the pistons and the bores, and then compared them to the nismo my friend had. my suggestion... go with the stock rplacement from a reputable parts store (napa) or winchester auto here in nor cal, or let me know and ill ship you one. hope that helps.

[holybushoffire]

I've had a Raybestos slave cylinder on my car for about a year now without any problems. All I run is the ACT street disc with the "heavy duty" pressure plate.

[soreballz]

I popped my Autozone slave in about 6 months. I'm running an Exedy oem replacement clutch, and I don't clutch kick at all.

Since then, I've been using a Z32 TT OEM slave cylinder. Its beefier. It isn't quite a direct bolt on, though. I had to use 2mm washers and longer bolts to get it to seat properly. If you try to bolt it down without the washers, you WILL shatter the housing of the slave cylinder.

EDIT FOR NEW KNOWLEDGE IN CASE ANYONE SEARCHING FINDS THIS: The stock '89-'90 240sx slaves are shitty and weak 11/16ths units. The '91-'98 240sx slaves are 3/4", same as the Z32 slaves, though, as stated earlier, the Z32 slave body is slightly different.

[alkemyst]

I bought an autozone / brakeware clutch slave and it installed ok and looked comparable to OEM. Only they had this in stock at the time.

I wanted the LUK which I think is the exact OEM.

If it fails, it's a 10min swap without the clutch dampener.

I had to shave down the bellhousing a bit and use 2mm washers and longer bolts to get it to seat properly. If you try to bolt it down without the washers, you WILL shatter the housing of the slave cylinder.

You know anything on the Z31 Turbo one...I can't find a definite answer. The slave is not rocket science so I am willing to bet your solution with 2mm washers and a little shaving works awesome. There is a ton of play in each direction. Being outboard more probably gives some mechanical advantage.

The nismo I have never heard a bad thing about, but at 3 figures that is a lot of mod money.

[soreballz]

^Dunno. They're cheap enough to try out though. I'd say just buy one. If if doesn't fit, clean it up and return it. lol

did anyone see what i said? THEY ARE EXACTLY THE SAME, i doubt having your slave farther out gives any kind of advantage since im sure nissan measured the length of the shiftfork before deciding to go with it. z31/32 is the same as s13/s14 trust me, brand i would suggest (aside from avoiding the checker, shuck, kragen family) napa, centric, or another direct OE replacement where i work we have access to a company called world-pac so we can basically get the direct OE replacement for any import. trust me theres is no better nissan slave than OE. why do you think the nismo slave is universal for all chassis. only difference between any of them is the side the bleeder screw is on. the only way to upgrade your clutch (hydraulic) system is your master not your slave. if you want to upgrade you slave buy a stock replacement and replace the sprin int the bore behind the piston with a stronger one, just trust me kids that all nismo did.

[soreballz]

^Dunno what brand parts you were looking at, but the OEM Nissan Z32 slave cylinder I have DOES have a bigger piston than the stock OEM Nissan S13 slave.


And the Nismo slave has a bigger piston in it than the OEM Z32 slave.

Oh, and I didn't space my slave out a bit just for shits and giggles. It was necessary for clearance purposes due to the Z32 slave being LARGER than the oem slave, and the slave's housing hit the bellhousing before it was completely seated.



Knowledge is power. haha

So you took a non oem part that is known to crap out, took it apart and found out it was all the same? I'll give you the benefit of the doubt and lets say it is the same. But they aren't OEM parts, just OE style.

So have you ever thought that your OE style parts just suck that hard to use the same hardware?

OE style replacements that parts stores sell tend to suck and crap out faster than OEM.

For all you people who are acting like the Nismo isn't any different than stock, that's just because you don't want to spend the money on it.

I mean shit, $200 isn't jack shit. Only like a day of work or something.
Come on poeple!

[CrimsonRockett]

That's like, one and a half day's worth of work for me.

Make $200 in a matter of minutes.

[Phoen_x_s14]

hmmm mind if yall post up what that specific part # the Napa slave cylinder is? I'm seeing different ones they have online.

[!Zar!]

Don't buy one from Napa.

OEM.

Nothing less.

[soreballz]

^Seriously. You can get an OEM one for less than 30 bucks. Why would you cheap out on a part just to save 10 dollars?

Fuck that. OEM ftw.

[alkemyst]

I mean shit, $200 isn't jack shit. Only like a day of work or something.
Come on poeple!

Assuming you are talking take home pay, I think the IRS/Census would like to know how most of the nation is pulling in over $70k year.

Now $200 is not a whole bunch of money, but that $200 could be better spent by many on other mods than just a slave cylinder.

[SleeperSx]

NAPA FTW!!! Its all I use!! Never had a part break or go bad from them in 4 years.

OEM is just as good, But Napa is not bad parts nor cheap.

Advance, and Autozone are the bad part suppliers.

were I live the average income is 25-30k a year, So that 200$ could be the difference between if I eat tomorrow or not. So ya its a big deal to some of us. I hate paying extra B.S to someone who is making a killing on something like that. Its just Non sense. If your Rich then cool glad you have money. But us poor boys make shit work and work well!!

[alkemyst]

I have found it's really the parts supplier rather than who is selling.

Autozone and the like have their 'store' brands, but they also carry LUK, Wagner, Bendix, etc at higher prices. I shop the brand and find out who has it cheapest.

I don't really get that other dude above saying all the slaves are identical. If so I am not sure where all the posts on how other slaves didn't fit came to be.

It's a simple bolton where even an idiot can do it.

It's possible that the Nismo is just a stronger spring on top of a higher capacity slave, but not many are going to play with sourcing springs until they find the right one.

Sort of like how Nismo's 248s are almost the same as the S13 248s except repinned at the exact proper location that rotating back 4 teeth doesn't put you at.

[djcobra]

I've just installed a NISMO Slave Cyl, Clutch Line, Pivot, along with an RPS Clutch (max street) and RPS Flywheel. Was there a difference? DAMN RIGHT THERE WAS! Looks like some people on here are cheaping out on parts and just like to bitch about the NISMO line of 'fine' products. For god sakes you guys drive a NISSAN, atleast stick/support their sports division products rather than bitch about it; so what if the price is a little high, if thats the problem then don't drive these cars! Whatever i've said what I had to say...

What difference did you notice with the Nismo Clutch line over a $20 SPL one or the like?

do you realize your telling everyone to go spend twice the money for a brand name when we are all talkin about using OEM REPLACEMENTS we arent comparing aftermarket products, the original question wwas if the nismo slave itself is worth and it seems that overruling opinion is NO, maybe if your car isnt a daily driver you want to go spend that kind of money but most of us have to use these to get around as well as have fun in so theres no way we can spend triple digits on something thats not a triple digit advantage. Id rather put $200 something towards coils or a gt2871r, thats all just IMHO :squintd:

thats what i was saying the slaves are all botlt on and are for all intensive purposes internally the same (as me and a coworker measured pistons and bore with a micrometer) although we did all only one brand (centric) we just wanted to know if there was a difference between the models (s13,s14, z31,z32) since we had heard that z32's were an upgrade, they are not. And any respectable parts store has springs of various sizes and strengths, we have a organized box that we let customers go through all the time. maybe just no one has the patience? but basicaly im sayin alkemyst knows whats up and so do most of the people on this thread except the people that obviusly cant read :stupid:

Look at where it says "3/4" as in 3/4 inch or 19.05 mm

http://www.nengun.com/nismo/big-operating-cylinder

"Bigger cylinder diameter (20.54mm) comparing with standard one (19.05mm) enables you to control clutch pedal much easier."

I have a Nismo. I have no idea whats different about it (and I'm not gonna take it apart to find out) vs. stock but it IS lighter than stock. Besides, is $120 really that much money for a completely brand new slave cylinder?

[Sileighty_85]

Damn only 120 Bucks! thats the cheapest I've seen so far.
But hell I'd even pay $150 for one.
I'll pay alittle extra for reliablity.

I drive to Mineral Wells from Lousiana, and Id rather not have to worry about my slave shitting it self on the highway 100 miles from the closest town.

Sure its an easy fix but its just an inconvenience id rather not have to deal with

Im not about to use a POS Napa, AZ,AAP, or CQ, slave or my Twin OS-G.
Hell im usin a Z32 Napa on my SR its already Crapped out 2 times in year on my stock clutch.

Now that i see that site got one for 120, now i can drop in the OS-G.

[atom]

It used to be even cheaper. I bought it from them for 105 last year or about 120 shipped to my door. Damn exchange rates.

[aNskY]

Besides, is $120 really that much money for a completely brand new slave cylinder?

when oem is 1/5 the price, yes, it is way too much.

[Wake]

second that +1 for you

[Geoff92]

how about the push rod , has anyone ever made a longer push rod on the slave cylinder? for what ever reason my clutch wont disengage anymore and i cant think of any other solution, just installed an exedy triple disc on a red top sr new slave new master, and my pedel adjustment is maxed out worked fine for a day and now wont go in gear!

[fliprayzin240sx]

^^^^^Tried bleeding it first? If you still have the clutch dampener loop, get rid of that shit.

But to answer your rod question, yes, that would work too. Its a cheat way of having to have to to drop your transmission to change your damn TOB carrier and TOB to something thicker.

[jr_ss]

Damn Flip, going back a few years...

Are you sure you installed the clutch correctly? Did you have the right TOB and TOB sleeve? Most likely that's the problem...

[lbogkush]

got generic for $5 at a local shop had for 1 year no problem with stage 1 exedy clutch i keep on forgetting to get an oem oh well

[aga]

i've ordered a nismo slave and a braided line, and the first posts in this thread kinda worried me that my clutch will be too soft...my clutch is the big coppermix (for 480hp i think) ...but seeing that the difference of the nismo is 20mm vs 19 , i dont think that will be the case, right?
