here we go again.....a bit of history......had car ( r33 GTR just under 400rwhp) for three years and about to put in my fourth clutch..

first one was twin plate exedy, liked it and it drove nice but only lasted 1 year, at $2500 + labour , didn't want to do that ever year, so I asked on here and rang Jim Berry- thought he was the answer so got heavy single, installed, ran in than on the first hard change to 2nd smashed clutch and gearbox (turns out it was an r32 clutch revamped with mega clamp :mad: ) Jim sent me a new one( r33 this time)

which I put in not having $$ ( after replacing gearbox etc ) to buy another clutch.. anyway after a year of it shuddering and welding itself to the flywheel I think its shagged too.. ANYWAY please don't suggest another Jim Berry, I'm not put another one in !!!! not here to bag Jim, he's a good guy, his clutches just haven't worked for me...........

I drive it quite a bit, about 15000km a year including once a month up the track about 30-40 hard laps each time aswell as other 1 and 2 day events ( motokana type stuff ) quite abit of launching, quarter miles etc and drive almost daily....

well there is the history and requirements, can anyone from experience tell me if any of the following will stand up to that and last more than a year ( or is that just asking to much ) or at least give me your experience with them......

NPC twin -- like the sound of these,,custom made and totally rebuildable with cheap off the shelf parts......?? @ $2200

Nismo coppermix -- read some good reveiws but how long do they last and are they rebuildable ?? $?

OS Giken -- don't know much but pricey and are they all push ( don't really want to change to a push type )

anything else I should be considering ?? :laugh:

Yes these are rebuilable no probs with the plates only and a machine

Read the Twin Plate thread so far so good that the clutch is almost a 10 out of ten

has some weirds things like Lots of Running in etc

PM me and ill tell you more

after destroying a extremme clutch in less than 6months and having them flat out saying NO to replacing it under warranty i went and looked for a Japanese brand clutch. Went with the Nismo Twin Plate (rated at 600PS, you can get a comp. one which is rated at over 800PS) costed me 1.6K landed. Very nice clutch very easy to drive none of the typical twin plate rattle. Hope powers perfectly and its not to heavy that it will destroy your gearbox.

Also the clutch can be repair (nismo sell the repair kits) and it comes with a chrome-molly flywheel.

I have had mine for 2years now running 400HP

wouldn't use anything else

Also who is installing your clutches? as poor install can results in damage to the clutch?

What are you doing to destroy 3 clutches in as many years?

only one destroyed , hard to say what went first clutch or gearbox, the others have just worn out------do fare bit of track work, events ( lots of launching out of the box ) 1/4 mile runs ( more launching ) and just general driving.. was told my old exedy twin just wore out due to driving in traffic..

as for install, first three done at reputable workshops , last one by me

Well, in my 30+ years of driving, including a lot of motorsport, I've never broken a clutch. And only ever replaced a clutch maybe 2 times, and only then because it seemed like a good idea at the time (gearbox out).

I've been running an exedy sports tuff performance clutch for 5 years now 64 runs at the drags,an a couple of track days plus heaps of hard cruising,no prob works beautiful. :nyaanyaa:

remember he is running a gtr with 400hp, the clutch will take alot more

Not really, considering the GTR is RWD until the rears start to light up.

Hence if he's breaking shit, he should be smashing pressure plates apart, not wearing a clutch out.

By the time ATTESSA kicks in to make it AWD, the clutch should be fully engaged, if it's not, then it's purely driver error by most likely too many revs, and too much clutch out quickly.

yeah not sure about that......... the ATTESSA is allways primed and doesn't wait until the rears lose traction, it's also controlled by the G sensor so the second the car moves from a stand still the fronts are ingaged ( to the max if your launching ) so as soon as you start coming off the clutch the front torque split gauge goes straight up.... so I would say there is a lot more stress and wear on the clutch in a GTR than a RWD car..

anyway thats my understanding..........

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
