Clutch for 250rwkw?

About a week after changing to the rb25 turbo, my clutch hasnt been too happy, for a few reasons. I guess the extra power has worn the clutch, and it had run out of adjustment, which resulted in no fre-play and has effectivly rooted the clutch. Ive found out that the gearbox whine is only the thrust? bearing because of no freplay, but im going to have to buy a new clutch.

Im after a clutch that i dont need to go on steroids to use, but wont need upgrading when i go for my proper turbo/ecu upgrade. What do you guys recommend, and how much would i be looking for the clutch, and how much extra would it cost to install?

Im guessing that the stronger the clutch, the more bighty it gets, so i know i wont get the best of both worlds. Im in brisbane, so where can be recommended up here?

I am going to be honest with you luke,

I have driven a R33 with a twin plate setup, and a R33 with a strong single. (with the same power output as yourself). Personaly i would take the single in this situation for 3 reasons:

1. Cheaper. (for a really good single your looking at around the $700 mark)

2. Doesnt rattle around like a 1986 VL taxi.

3. It will suit your power application perfectly.

if you would like the best of both worlds: (play & grip) i would recommend getting a cushioned ceramic button clutch:

take a look, they deliver anywhere.

Go the twin plate.

I bought a 9 button ceramic-ferride Xtreme clutch when I toasted my stocky. It was ok for a while, but started protesting after about 6 months - this is with only just over 200rwkw.

I then got a twin plate, the clutch I would have got in the first place had I the funds at the time. Much better, and I know it will hold even when/if I do the 3L conversion I have planned (if the RB25 dies).

A single plate clutch that can handle 250 rwkw will be grippy as hell - therefore you will shudder every single time you take off in first, even worse when you are taking off on a hill.

I know this because I have one. Next clutch I get will be twin plate.

matlowth (on this forum) is running a full faced organic single plate clutch. also producing over 300RWKW on a RB30/25. and drives it to work.

proof is in the pudding.

listen if youve got the dosh get the twin, if your scrap for cash grab a good single.

Probably best to buy direct from Japan, will save you some dosh. I got mine 2nd-hand and had it rebuilt:D I had a Nismo 5-puck clutch in my car, only last a few months and was a prick to drive. I'm much happier with the drivability of the twin-plate:D

You get what you pay for. There are single-plate clutches that will handle that sort of power, but they won't be as consistent as a twin-plate. I used an OS Giken twin plate in my R34 with 280-295kW at the wheels. It could handle any kind of abuse and still behave almost like a normal clutch in traffic.

Thanks for the reply.

I just noticed I put the wrong turbo on the post.

I am acutally doing a very similar build with a HKS 3037S so I think thats why I put the wrong one down (edited:)).

Congrats on the time - into the 11s with street tyres awesome!

Also good to see someone sticking with stock internals and making such good power. Seems so many people here dont think it can be done safely, when all they need to do is look to the birthplace of the skyline.

My head gasket and cams arrive on friday:)

Once again welcome to the forums, good to see you here.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
