One thing that is bugging me, Exedy make the Nismo clutches correct?

Is the Exedy equivelent to the Coppermix just painted purple (Exedy) versus painted red (Nismo)?

I believe they're different. Even though they might be built by Exedy, the design would be from Nismo. Isnt that the same for injectors and turbos? As far as I know, the likes of Nismo, HKS etc dont make their own, someone else manufacture them to their design/spec. The outcome is a superior product at a premium. You can argue its not worth the extra dollar but its up to individual. I'm dead set certain I'll get Nismo at least for clutch, injectors, fuel pump and AFM. Turbo? The slight better response from HKS isnt worth the extra money for my application. You can only research that much and at the end of the day its up to you to decide what you want and you should know what suits your budget and application best.

Have you looked at Jim berry clutches. I remember reading a while back a VL turbo was using one of there clutches and did multiple 9 second passes and was still easy enough to use on the street. I wouldn't mind betting that it would be a cheaper option as well.

Multiple 9sec doesnt equate to easy on the foot. So far, I've narrowed it down to Coppermix and ATS carbon. And yes Jim Berry will 100% be cheaper. Not a lot of clutch cost above $2000.

Fair comment,

the OS admittedly bites very very hard, that redline to 2nd gear snap where you can just hear the "thunk, chirp" sounds brutal.

but honestly I never had any issues even in bumper to bumper traffic, well maybe it was a bit jerky (the higher revs you talked about) but overall I really like my clutch and did not like the nismo at all !

it had a super high friction point eugh.

Also probably should be noted I have a Nismo master cylinder on mine (bigger one) so that makes it more comfortable on the foot, although I don;t really get the people who whinge about having a heavy clutch, unless of course you have a leg injury/sore foot etc.

If you have a choice why go the uncomfortable way? It something you can choose. And my choice is easy on my foot.

Good review from you though. You're the first I know that didnt like the Coppermix. Up to today Coppermix has been the perfect scored one... lol.

Looks like the 300 I'm saving by going with standard model can be spent on the slave...? Hahaha.

Had a coppermix single on my 300rwkw build and it was excellent, only probs i had with it was riding it a touch at high revs to save the drive line (didnt really like that):whistling: Though i did perform an 8 grand launch side steping the clutch and it gripped up sweet and went like a rocket

Now chosen to go the coppermix twin plate for my 400rwkw build, should be a strong and streetable clutch....Cant wait to get it on the street!

ummm are you serious!?

I had a single coppermix in my old GTSt and it was slipping at anything over 250rwkw... had to ditch it... are there different single coppermix for GTS and GTR I wonder?

I have an old GMAX twin (8+ yrs) and its still holding the power even on full bore changes... but its time is coming and I'll be going to the coppermix twin with no hesitation :cheers:

yeah no

just the words out of exedy's mouth. when i got a clutch kit from them with a valeo pressure plate, i rang and inquired why and they said 'valeo make our clutches, the one you got just isn't painted pink'

they said i could send it back and wait for a pink one but i didn't bother and havn't had a problem with it

just my experience, may have changed now but this was only about 6 months ago

just an exedy heavy duty, yeah thats what i meant about them being the same because in reference to the coppermix above apparently its made by exedy but has a valeo clutch plate.

thats why i say same/ same, probably should have made that clear the first time

So does it use a power booster or not?

C spec is 780PS based on the datasheet. I'm assuming thats fly too. I think PS and HP are about the same.

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
