R34 25gt Clutch

[clip14]

what kind of clutch should i be looking for?

i had a search and found all different types of clutches for rb series.

push/pull

6bolt/9bolt

225mm/bigger diameter mm

for a r34 rb25de manual

[T04GTR]

i would say its a 225mm one

surely someone here has upgraded their clutch in their r34 rb25de?

I'm getting a cash job done for the clutch change, so would be best if i turned up with the right clutch kit!

I'll be very interested to know the answer to this as well.

My gut feeling is that a HD kit for the R32 RB20DET would be the right option ( PUSH type / 240mm Dia ) but I would really love to know for sure !

I just emailed Exedy and they told me the Heavy Duty part number for R34 GT (&V) with RB25DE NEO is NSK-7333HD

[clip14]

thanks for getting that info.

do you know what that part number clutch means though?

e.g. clutch diameter, cover bolts, push/pull type etc?

Actually, after searching a bit I found the following

SPORTS TUFF Clutch Kits (Australian made for improved performance)

Heavy Duty Kit: NSK-7333HD

SKYLINE- GT-T

Year Application

98-on

R34, 2.5 Ltr, RB25DET (Pull type)

I now have less confidence in the response from Exedy being correct

[TokyoTaxi]

Spoke to the guy at Exedy again and he's positive that the NSK-7333HD kit is the one to use.

What someone ( I'll try to but it won't be for a while ) needs to do is to unbolt the slave cylinder and pop the clutch fork dust boot off and see if this is a push or pull set-up. If it IS a pull type clutch, the above kit should be good.

If it's a push type clutch, I would be looking towards a HD early R32 GT-R organic kit.

I can probably do this the next time the car is up on stands.

You info above though suggests that the clutch set up is identical to the r34 GTT setup. this would make finding an upgraded clutch a lot easier.

[TokyoTaxi]

See, here's the thing. AFAIK, R34 GTT ( RB25DET ) has a PULL type clutch. I'm almost certain that the R34 GT ( &GTV ) use the PUSH setup which would make them equal to R32 GT-R RB26DETT ( early ) and R33 GTSt RB25DET ( both are 250mm dia from memory ). If THAT is correct, it would be great ! That would also mean the rep for is Exedy wrong.

Can't wait to put this one to bed !! It's been bugging me since I first looked under my car years ago

I got a new organic clutch and a heavy duty pressure plate installed here in melbourne for a gtt with 230 rwkw.

The pedal is heavier than stock but its a nice clutch. reused the original flywheel after machining it.

Hope this helps, i originally got an exeedy clutch and hated it. mind you it was a carbon one,

DONT GET A CARBON CLUTCH PEOPLE!

Turned into an expensive exercise.

Goodluck

thanks guys for your replies.

have replaced my clutch. 240mm 9 bolt push

got a carbon kevlar full face plate, upgraded pressure plate, solid centre (unsprung).

its very heavy and horrible for the street, but seems to be doing fine at the track

So the r34 n/a's are a push type clutch not a pull type?

Cause thats really gonna piss me off if it is cause i just ordered a pull type clutch
