Exedy Clutches - Advice Needed

[AiR]

It's probably been brought up many times but I looked through the threads and they don't really answer my questions. I need a new clutch and I got a few quotes for some Exedy clutches but wasn't sure which one would be best suited to my car.

Heavy Duty Cushion Button - $515

Sports Organic - $721

Race Ceramic - $915

Sports Ceramic - $1073

Not sure how much power is at the wheels but its an R33 Gts-T with E-manage computer, front mount cooler, full exhaust, bov, apexi air filter, running standard boost atm. I don't drive it every day but it will be used mainly on open road. Basically I want something that will transmit maximum power to the wheels while still being suitable for road use. I don't care how grabby or heavy it is but don't want something that will wear out too quickly if used in traffic. Currently have a heavy duty duel plate clutch, not sure what brand.

Budget: $800 approx

Any help appreciated!

if you've only got a budget of approx 800 beans theres only 2 choices really, the first an second ones on your list, but wat you've also got to factor in the cost of fitting, machining of flywheel(which you'll have to buy a standard/aftermarket one if you really do have a twin plate) the brass bush that sits in the back on the crank, its going ot turn into an expensive job if you dont know wat your doing.

also wats wrong with the current clutch thats in your car?is it worn out/buggered or you just dont like it?

For the setup you discribe I would recommend either the Exedy Heavy Duty Cushioned Button or Sports Organic. My preference would be the Sports Organic, it's east to drive with and hold good power figures; I use and cannot fault it. Please be aware that the Sports Organic and Heavy Duty (organic) are two totally different kits, they share neither the same clutch plate or pressure plate.

I also offer Skylines Australia member better prices on all kits you have listed above, the list can be found within the following link:

If I don't know what I'm doing?? I wont be installing it myself and I won't be buying any parts or getting any work done until I know what the best solution is. $800 is approximate and is for parts only. The problem I am having is the clutch is slipping when I accelerate without dropping down gears. I was told that it's caused by the worn out clutch plate but is it more likely to be the release bearing? I will be taking the care to get looked at this week but I thought it could be easily diagnosed by someone who has had similar problems.

ok then. if you want to get a new clutch id go for the h/d cushioned button one. handles my 300hp, woman can drive it feels like a standard one. if you've got a twin plate one in there atm i'd pull the box out find out wat brand and i'f i liked the drivability of the unit get new parts to rebuild it if you can

If you are able to change gears easily than you can cross the release bearing off your list. It appears that you do have a slipping clutch, the easiest way to confirm this is to find a good hill, while still tavelling at a good speed place the gearbox in either 4 or 5 and give it full throttle. If your revs climb rapidly than you have yourself a textbook slipping clutch plate.

Yeah no problems shifting except when its cold its a bit hard to get it from 1st to 2nd without double clutching. But as soon as it starts spooling it'll slip in any gear.

Sorry to cut in on your thread but:

Sullivan: I am up for a new clutch for my 33 also. The only mods are cat back exhaust and intake. I will be finishing the exhaust off, but most I'll be aiming for is around ~170rwkw. Will the Heavy Duty kit (for $396) be sufficient for this purpose? I use the car for mainly city driving to/from work with the occasional hills sprint on the weekends. I don't intend on any drifting ever, and my attend the drags once or twice to find out a time.

Thanks

I just fitted the Excedy HD clutch to my R33. Its supposed to hold 240KW ATW. I also fitted a Lightened flywheel and short shifter in the process. The clutch is actually lighter to press than the standard one was. I also put auto trans fluid in the gearbox instead of the 80W90 and the gear selection is heaps easier. It used to be pretty hard to engage gears when it was cold and I could never engage 1st until nearly completely stopped. Now it a lot better. I just hope the lighter fluid doesnt cause excess wear in the gearbox.

Courier33,

Drop that Autotrans fluid.

I had gear selection problems in a 2yr old VS 5ltr 5speed Commodore I bought years ago. The rather large new car dealer dropped autotrans fluid in the gearbox and YES it did make it 100% perfect to shift but the box was dead just under 6 months and approx 15,000km's. Syncro's were completely shot as were bearings. The box got noisy and rattly very quick and also began sliding out of fifth.

Definitely not recommended.

I had an extended warranty on the car but unfortunately they would not cover the whole rebuild cost as the cause of failure was due to the car yards dodgy patch up. I was told to have the car yard fix it and they/the manager said simply "piss off, take us to court".

So I definitely won't be purchasing a car from the 'great great guys' ever again.
