We have a single plate, and are producing 467rwkw...never been a problem...and its copped a fair bit of punishment too.....its a JIM BERRY special.

yeah, but a Jim Berry certainly isnt the run of the mill clutch by any means of the word.

His twins hold 600kw+ no worries ;)

everything has its price

IMO - go for something rebuildable.

Remember if you have one plate, two is going to cost more.

Im running an OS Twin, awesome clutch ive never had problems with. It was almost shagged and still gripped without issue.

Rebuild is $1500 (plates themselves around around the $600 mark give or take)

You'd think a single would be cheaper, but how long does it last?

R31Nismoid: That was one of my initial concerns and part of the reason why I posted this topic.

I do not want to install a single plate and have it die on me in a year.....then get a rebuild when getting a twin plate in the first place would have been cheaper.

But judging from the response I have got from this thread, I think a single plate would be sufficient enough for me.

i have an OS Giken twin plate in my car, but it's the hard core solid centre one, not the sprung centre. it certainly cops the punishment I dish out, but it's a bit of a bitch for city driving, and it rattles when your foot is on the clutch (makes people think your car is broken). Nick (blitz) has just installed a nismo twin into his GTR. I dunno if he's given it much punishment yet, but it sure seems a fair bit more civilised than my OS Giken one. can't fault the performance of mine though. plenty of 7000rpm launches (in both RWD and AWD), a few track days and no dramas. :D

Well I am getting a Jim Berry single! once that is in the car will be tuned again for 1.4 BAR and I'm sure to see 300awkw and from all reports, Jim's clutch will do this in its sleep....

for what its worth, my understanding is that a single has more meat on it that say a twin or tripple, being that it is still in the same space the single would take up... so I would say a good single will outlast a twin in most cases.... which seems to be backed up with the time frame most of jims clutches last over twins... and they seem to be half the price of a decent twin too :D:):):);)

oh and I think I must hold a world record!!! (Jim on and off the phone with clutch info and spec's etc in 6 mins 34 sec!!!!)

Tell 'em the price sun?:(

my os giken clutch rattles as well. Do you know if this is normal, as its quite loud.

We have 3 X OS Giken multiplate clutches, 1 X twin plate in the GTST and 2 X triple plates in the GTR's. They all rattle when not under load, however they are what I call "competition" multiplates. I understand that OS Giken also have a range of "road" multiplates that have springs between the intermediate plates and the cage that stop the rattle.

I get might sick of people rushing up to me and telling me to turn the engine off as it has bad big end rattle. :chairshot

"It's OK, its just the clutch",wears a bit thin after 20 or 30 people per race weekend.:(

my OS twin only rattles with the clutch depressed

since rebuild its a lot more quiet as the plates arent as worn and its definately rattling less

I have an ogura racing super single cerametallic. Had the centre plate replaced due to a destroyed spring, but may need to look at another clutch. When driven hard, after a while produces slip which has only just started happening. Will need something stronger as the new centre plate was less than 10000kms old. ;) Money wasted

from scratch?

or supplying a dead clutch to be modified?

I bought a dead 3 puck nismo clutch for $100, sent it to Jim Berry, and he made a 3800 pound carbonic 5 puck clutch for $800.

Factor in the several hour long mobile phone calls to Jim, and i got an awsome clutch for under a grand! He certainly can talk! Better that someone who doesnt give you the time of day though!

Shaun.

HypeR33...how much power are you making ???

From what I have read the Ogura racing is rated at 450HP. I am making less than that at just under 250rwkw. Plans in the works to bring the kw way up. Will definitely need a new clutch then :goddam: should have used the $900 spent on the new centre plate towards a more powerful clutch, but also need a new flywheel coz it has an Ogura racing lightened flywheel with the clutch.

I purchased a 9puk Ceramic 1100kg in anticipation of 300rwkw.

I bought it from Tim Possingham the previous owner of www.horsepowerinabox.com 1yrs ago for $600.

I'm making no where near it yet, I have no doubts it will hold.

The same clutch is in 2 other 300rwkw monsters I know of. Whatsisname just under 300rwkw & another 2jz Supra making a shade over 300rwkw.

Its quite a nice clutch to drive, reversing is the only time I find it bounces the drive line a little.

tell me about it. i get looks when I'm at the lights, foot on clutch, select first now everyone within 20 metres of the car is looking at me like i'm must be some kind of idiot not to get that death rattle seen to. quite funny though. those that know just give a little smile... also, like you said the solid centre OS clutches really are a competition style clutch. not very friendly to tootle around with, but awesome for track work, big launches, burnouts etc whatever your heary desires. I think if/when it dies i will either just rebuild it, or try one of the new nismo ones.

    • Can perhaps see how the R33 appreciators would think so.  
    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
