I have no idea what these are and where to get them :D . Can anyone enlighten me as i've been informed that my slave/master is rooted.

Sorry for the noob question.

depending on what model you car is

master cylinder - located infront of driver side (dont mistake for brake master cylinder - refer to owners manual)

slave cylinder - located under car along side the transmission

shop around for prices

Hmm well I have a GT-R gearbox so i'm guessing I need this one => http://www.kudosmotorsports.com/catalog/ni...3334-p-384.html

Is it worth changing the slave as well to be sure? The symptoms are that as it gets hotter the clutch pedal moves higher up the pedal to the point of it slipping on 35+ days.

33gtst masters do fit on 32gtst's (need to modify the rod slightly), the 33 item is shorter and people use them when putting forward facing plenums on.

32gtr master is different as it is vacuum assist (and have special cutouts in the firewall etc). If you are putting a GTR box in a GTSt platform then you have to use the GTSt master cylinder.

I also have a funny feeling that GTS4 is the same as GTSt, not GTR.

Yes I believe you are correct as well.. and I don't want to trial by fire :P. I'm sure the GT-R unit uses the booster, but i'm also sure it is often removed because it doesn't add a lot to the equation. In this case to people switch to gts-t masters?

GTs4 here, GTsT master cylinder.. piece of piss to change. Bought mine from kudos as well.

master and slave package --> http://www.kudosmotorsports.com/catalog/ni...-gtst-p-61.html

pic there is the same as what I have bolted on my car, after I had gotten a few frights with the clutch pedal sitting on the floor.

Ya i've had advice from professionals that I should use a gts-4 master and gt-r slave :S. But most advice points to gts-4 master and slave. The question I guess is what is the difference in slaves? do they all bolt up the same (even push on pull?).

Get under the car and look. In the package there is a pic of the gtst one, looks like one mounting hole each side of the body. On the gtr / gts4 one there are two holes on one side.

If your car is push, it will have the clutch arm to the rear of the slave cylinder, pull other way around towards the front.

If things are still not clear, get a picture of each and throw it up here.

Hehe car is at a workshop atm.. but thanks for that advice I will definitely check ASAP. I definitely have an early R32 GT-R gearbox (push type) as that's the clutch I just put in it :P. I also definitely have a GTS-4 master cylinder.

gts 4 slave cylinders are very slightly different. GTR slave's have an indent where the nut locks into to stop twisting. I have a spare GTR slave and master cylinder sitting at home. Might want to change the seal on the slave (not manditory) and the master is in excellent condition (used).

The question is.. is there any functional difference between the two? as in running a GTS-4 master but a GT-R slave would leave the clutch engagement at the wrong spot? Or is it simply a difference in the mounts? I'm certain the GT-R and GTS-4 masters have different ratios.

.. Mine works.. on an ORC twin and feels good. Just adjust it for the right pickup point. Massively light compared to the original single plate that was in there, ex wouldn't drive it cos took too much force to hold the clutch pedal in.

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
