Does anyone know if an R34 clutch is the same or compatible with the R33 one?

I am looking to buy the daikin / exedy sports organic clutch but so far I am having a hard time finding out if they make them for my car. Basically, they dont, in Oz at least.

I have been talking to Daikin Aust. all week...the only thing they can offer me off the shelf [which they think will fit] is called a Premium Duty Clutch and will cost $800 just for the parts - this doesn't include a lightened flywheel either!!!

Now if 33 and 34 are the same then I will just get the exedy sports organic clutch! I'm talking about GTT / GTST here, AFAIK 33 & 34 GTR are interchangable but not from gtr to gtst etc...

Thanks guys ;)

The only cutches that I know of that are interchangeable are the R32GTR and R33GTSt.

I can only suggest you contact www.greenline.jp

If you tell them what sort of clutch you are after, they will check with their suppliers (HKS, Trust, Nismo, OS Giken, etc) and give you a run down of what is available. They are very careful when they sell parts that they are compatible. They didnt want to sell me a Trust Type R as it was for GTR and they knew I had a GTS, until of course I explained it was being custom fitted.

Also, you will probably end up with a better quality clutch at a competitive price.

Nismo.. i have a Excedy.. not sure exactly what type, but it most likely is the sports organic one. While its fairly nice, it doesn't instill great confidence and i have a feeling if i add more power it may pack itself in fairly prematurely (it was installed about 20,000km ago). The thrust bearing is already quite "clunky"

If you have the money go for a twin plate, especially if you want to go over 200rwkw. Depends of course whether you plan on further power for your car or not.

Thanks guys :(

Pred: I am checking out a dump/front pipe as we speak :) this could push me up to around 190rwkw at a guess based on current power of 180ish on the standard front exhaust section and cat... Performance wise, I won't be doing much else for a while...if at all! I only read good reports about the Exedy in other threads so thanks for the warning.

I don't think I want a twin plate as I have heard they are far from stock in terms of driveability user-friendliness. I have heard that multi plate, brass and ceramic types are ALL either ON or OFF in their operation. I would prefer just a stronger version of what I already have - which I believe is the factory spec clutch, but not 100% certain.

I test drove a twin / triple plate 34 GTT a few weeks ago and I didnt like it, very heavy pedal and very easy to stall - my car is a daily driver with the 1 or 2 time-a-year circuit / drag run...

Steve: I will send a query off to greenline, thanks. There still doesn't seem to be much knowledge in Melb / Oz [auto industry] for the 34s...

I guess though the Excedy is pretty nice to drive, and does behave like a normal clutch and grips very nicely when you tramp it.

I guess because i drive mine every day, it takes a bit of punishment in start-stop traffic and i probably do ride the clutch a little which would wear it out quicker.. Unfortunately, in start-stop peak hour-traffic its a bit unavoidable .

So maybe that would actually be a good choice if you can get one for the 34.

Hmm, well I have also heard that they arent all that great, but each to their own.

I can tell you that either a ceramic clutch (also not recommended due to fatigue after about 6 months with just over 200rwkw) or a twin plate (highly recommended) do NOT have on/off operation. You can slip a twin plate better than a stock one or a ceramic. Yes they are a bit heavier, but you get used to it very quickly.

I havent heard too many people that own twin plates bitch about them, I have only heard praise, and I love mine too.

      I say this and there’s a Nistune r34 GTT MT ECU for sale on eBay.de but I need to figure out compatibility between the AT harness and MT ECU - TCS considered. I figure this HKS SLD is a quick bandaid anyhow.

      It’s a high priority but I can’t get a Nistune in before my next Nurburgring trip. 180 is pretty easy to hit on the back straight of the GP course. I should have got the Nistune installed in Japan - my friend offered to solder the board - but I had the same problem of just not wanting any downtime for the car. My guess is this winter when I rebuild the rear subframe  (which is what I said back in 2022)

      To add to that very useful summary, even in the race/rally r32 gtr I have good quality, new(ish) poly bushes everywhere because that is what rules require, and the handling is excellent. Of course, the car doesn't do many klm but I'd still expect poly bushes to last better in road use than sphericals (especially as I have a couple of klm of dirt road to stuff sphericals up) I would change the front upper arms to spherical if I was allowed to, because the poly bushes flog out often, but otherwise new bushes (and ball joints) and a good alignment can make a world of difference

      Any chance you can get a Nistune board installed instead and set the speed limit to whatever your tires can handle?

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf
