Hi.
I need a new clutch for my gearbox.
It is a factory smallbox behind RB20DE NEO.

What options do i have?
If iam not mistaken the gearbox should be the same as in R32 GTST and Nissan S14/S15?
I found some Xtreme Clutch Stage 1 for S14/S14 (i dont know if you know the brand) (UK)

OR...is the clutch same as in the bigbox from RB25DET?

 

Thank you!

If it's a factory 20de manual probably has the 6 bolt flywheel in which case the det clutches won't work as they're 9 bolt.

Really? That's piss weak. I didn't know they hobbled the shitboxen that badly.

OK. So probs need to buy a flywheel too. But that's not too bad.

Yep, yeah would need to do the flywheel although the 6 bolt NA clutch can handle a 20de if just wants to replace the stocker.

Ok so no 4cyl clutch...

Yeah it is a factory manual.

So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?

 

EDIT: https://www.ebay.com/itm/224291042776
Is this ok?

 

EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap)
It will be there for a little while.
Iam planing to do bigbox or BMW tranny..

That's essentially the clutch that I have behind my Neo. Big box of course, but it won't matter that you have a small box, as you won't have it for too long.

Being behind an RB25DET, we know he won't have the small box for long at all...

So it should work in my case? 
I does not say R34 but it say push(i have push gearbox/clutch right now)

No i wont...and i do not drift/race or do anything crazy with car so even a small box should be ok for a couple of months

Are you planning to ever come on boost with the RB25DET?

The torque of the motor alone will break the little box. It's not a matter of if, it's when.

That's because R34 RB25DET is a pull clutch gearbox.

I have that clutch, behind 25Neo, in front of R33 gearbox.

I have brand new R34 turbo gearbox, in a box (cardboard) in the shed right now, and it will be getting used with the same engine and clutch, because I also have, in a much smaller box next to it, the front plate to convert the new box to push clutch.

A couple of months of gentle driving will be fine. There is a risk that you will kill it. A heavy workout will probably kill 3rd gear. Continued use will wreck the input shaft bearing.

Hi

I wrote to the xtreme clutch and they wrote me this:

Thanks for contacting us.
I already spoke with engineering team and was told that RB25DET with a non-turbo fs5w71c gearbox would not work. It would not hold the horsepower and does not bolt to that engine without some sort of adapter plate or modified bellhousing.
 

 

I know about the power(it will hold stock power)

But i rly dont know about not bolting to the engine without some adaptor??

Is this true? I thought it should mate up without any problems...

It's not true. RBs only have one gearbox bolt pattern. I mean, I was surprised that there was a different clutch bolt count on the weak NAs, but that's on the flywheel, which is not part of the engine.

Yeah i thought so too...but iam kinda confused what is what and what to get to make it work.

I know i need a push clutch(i get that with that kit i post) 

It has flywheel too and from what i found it should "mate" with RB25DET NEO.

But i dont rly know about the bolt count cuz i saw many videos about clutch on RB25DET/NEO and all of them has 6 bolt pattern...

Like here for example...

And if i google clutch kit for RB25DET NEO like "all of them" has 6 bolt flywheel...

Look, it's very simple. The 6 bolts or the 9 bolts are interface between the clutch and the flywheel. Any flywheel will bolt to any RB crank - the bolts in the centre there are the same same.

So, you just need teh flywheel to suit the turbo clutch. That's all. No more to think about. Get both, boost off into the sunset. (only without the boost).

      Rb25det timing belt position on cam gear

      By drifter17a · Posted

      I just changed the timing belt on my RB25DET NEO and wanted to get some opinions. I’ve been super cautious, did a lot of research, and took my time. I’ve driven the car, and it runs fine. After warming it up, I revved it to 8000 RPM a few times—no issues, everything held up.   After the drive, I heard a noise that I think is either the clutch or possibly a tight accessory belt. It’s not constant, just comes and goes.   I took the timing cover off to double-check everything:   Belt is on properly, Tensioner is tight, Did the 90-degree twist test—belt isn’t too tight or too loose.     What still worries me is that I noticed the belt seems to sit a little toward the front edge of the gears, especially on the idler pulley. It even looks like it’s slightly coming off the edge there. Is that normal?   My old belt (5 years old, ~3,000 miles) also showed a bit of wear on that same edge, so maybe it’s just how it sits? I’m probably overthinking this, but since it’s my first time doing this on a NEO and the engine is forged, I really don’t want to mess anything up.   Also, I’m thinking of swapping to a clear front timing cover with the glass window. Would you recommend NITO or HPI? HPI looks reputable and their covers have 2.5mm thickness, but not sure if there’s a real difference between the two.   Any advice or reassurance would be much appreciated!

      Powder coat on mating surface

      By GTSBoy · Posted

      40 grit sounds about right, to start. You make some decent cuts/damage in the coating with that, then rapdily scale up to maybe 80 and 120 for the bulk of the actual removal, then fine it off to 180 or 240 perhaps. No need to go any finer than that, and maybe no need to go even as fine as that. Wrap it on a big block and have at it. At least on the hub face.

      Hiya!

      Do the GKTech rear lower control arm mount relocation, and either alloy subframe inserts or very stiff subframe bushes. Traction is going to be at a premium!

      Hello,   My name if Frederick, i'm 30 years old and I live in Belgium, Europe! I used to have a Nissan 370z daily but since I got a company car I turned that into my seattime driftcar. About 3 years ago I also wanted something older with more feel, so I got an R32 GTST with an rb26 engine. I am now getting the rb built to have around 800hp and it's close to being finished. I'm very excited for how it will drive and how driveable it will be! Regards, Fred!

      ENR34 - Inner Tie Rod is unique part! Replacement?

      By AdiR34 · Posted

      Appreciate the insight! Talked to some local folks and they basically told me "it's not that deep." As long as the threading on the inside matches what's at the steering rack, everything else can be constructed-to-fit. There are full aftermarket kits I can use - probably better for my car overall since it's lowered.  Example: GKTech M14 Super Adjustable Inner Tie Rod Set - Nissan Skyline R32 R33 R33, 240SX, 300ZX, 350Z / Infiniti G35 M14I-TROD-2 gktM145-TROD gktM14I-TROD - Concept Z Performance (These can be packaged with their "high misalignment" tie rod ends).
