Hey all, had another question which I need help finding the right advise for. I'm needing to replace the clutch in my Series 2 Stagea RS4S shortly and was hoping somebody on here could help me source the right part number for a replacement clutch kit by exedy.

Till this point I was under the impression the Stagea has an R33 GTR gearbox fitted up as factory standard therefor I should be looking at clutch components that suit the 33 but after searching through a few posts already I haven't been able to find a definitive answer or part number.

If anyone has had their clutch replaced using exedy parts I would greatly appreciate knowing what they had fitted and their thoughts on the clutch after having it installed.

Thanks in advanced.

Update

I've got the correct part numbers for the corresponding clutch kits to suite a Series 2 Stagea from 98-on they are as follows for everybody's future reference.

Clutch Size: 250x25.5x24

Pull Type Clutch to suit RB25DET NEO

OEM Replacement: NSK-7333 / $941.20

Heavy Duty Kit: NSK-7333HD / $1,079.95

Heavy Duty Button Kit: NSK-7333HDB / $1,186.95

Heavy Duty Cushion Button Kit: NSK-7333HDCB $1,450.70

i just got the jim berry clutch and im more than happy with it. im fairly sure it was around $900 for him to rebuild the r34gtt clutch thats in the gtr box to a higher clamping pressure and it shits over my mates heavy duty xtreme.

The NSK-7172 series suits all GTR variances from 1993-on, so late model R32 GTR's all the way through to 2002 R34's that feature a pull-type clutch. Coincidentally it also appears to fit Series 2 Stageas as well.

The NSK-7333 suits 98 model-on R34 GT-T's as well as Series 2 Stagea's so it appear that Nissan have made the fitment sizes identical between the GT-T and GTR of the same period probably for convenience.

I would assume the only real difference (if any) is perhaps the torque capacity of the GTR (NSK-7172) clutch may be higher but this I can't confirm.

yer its possible both clutches are the same. kinda weird, as i said that what i have in mine now. exedy has quoted that there nsk7172hd will only hold 363kw at the fly and do not recommend use in stageas. i had a heavy duty put in and i already regret it. its starting to show signs of slipping. (only a few weeks old). my brother inlaw had the same clutch fitted to his r33 rwd and it only lasted a week. but his car has got a few little mods i think its about 300hp atw.

have you bedded the clutch in properly? your supposed to drive really softly for about 1000kms before you go anywhere near WOT otherwise it will slip

will also f**k up if you didn't get the flywheel machined

And cleaned properly!!! machining cast will bring carbon to surface and if not cleaned with solvent will cause slipping & shuddering.

He guys.. a very strong bump here, but I'm wondering if the above information is still valid? Has anyone else gone down a different route and/or have any recommendations in regards to replacing the clutch?

I'm really happy with my Nismo twin-plate Super CopperMix. It cost a fare wedge of cash, but it's light to use, not too bitey, and should easily last quite a while even when (or if) I ever bump up the power levels.

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
