R34 Gtr - New Clutch

[(OO)SKYLINE(OO)]

Yeah I didn't mind the "rattle" noise the twin plates made.

My HKS one did that but it was quite loud and ppl would say "What's that tearing noise..?" LOL!

Ppl who know clutches would only know what that noise is...

If you'r car is stock and will remain stock, personally i think a $3k Nismo Twin plate is slightly overkill.

Especially if she's a daily driver and won't be seeing any track time or constant hard launches.

Why you would fork out for a clutch designed to hold double if not tripple your planned power baffles me.

True.

That's why I went stock GTR clutch plate.

They do have a lot of grip, think about it, the GTR came from fractory twin turbo, you expect Nissan to put in a heavy duty single plate.

OEM is a good way to go if your only doing light mods and/or keeping it stock.

The Nismo twin isnt an "on" or "off" clutch like pretty much every other multiplate option.

Ive driven exedy twins aswel (nismo clutches are sourced from exedy then modified and resold), the difference is shocking. So far none of the other jap brands are close to the nismo IMO

Only problem with them is that the highest rated power for an R32 with standard gearbox is 740hp. If you stick an R34 getrag in you get a higher rating of 780hp. Both of those numbers are for the C spec versions (they rattle when clutch in). The C spec versions are a bit more costly but not by much, certainly not by enough to put you off getting one. Once you wear it out though, places like NPC can rebuild them to suit more power if needed. Also, if you can, buy one in stock in Australia, as they're fkn heavy to be sending by mail

Cool thanks!

Stock GTR's? lol, who has them these days

They all get modded, its just a matter of when

Ok, lets rewind! Sorry I read all the posts but I was in a hurry. Now I have gone though them again.

So sounds like the Nismo one is the way to go, I never thought they would be so expensive!

With the nismo one, do I have to replce the dual mass fly wheel? No mods needed with the Nismo one right? Lets just say my clutch jas been changed b4, and the dual mass fly wheel has been removed, is it easy to buy another one and place it back in?

With this rattle, is it quite loud?

no, its a quiet rattle like a loose syncro sorta...

most aftermarket clutch kits come with a dual mass.......so MAKE SURE IT COMES WITH A FLYWHEEL

You do need to change the stock flywheel, they are not compatible. But the good thing is the Nismo clutch includes a lightened flywheel already. It's also a straight up bolt on and a pull-type clutch, unlike a lot of other aftermarket clutches these days which are push-type (hope I got that right) so you need to buy all these f**king extra bits to make it pull-type, if you can understand that lol.

Yes the OEM GTR Clutch system is a push type

alot of aftermarket clutch kits like OS-Giken etc are a pull type conversion......

push type are not a bad thing.. in most designs, the Push type is better than the Pull.

that rattle isnt created by the Twin plates....

its most likely the lack of the Dual mass flywheel.

How do you mean by lack?

As in I didn't have a Dual Mass Flywheel?

[NISMO]

Generally most twin plate kits will come with a lightened flywheel, which is different to the dual mass stock items. The dual mass flywheels dampen the noise and vibrations.

Ah ok...

So that means I did have a lightened fly wheel, cuz it made noises...

yep

a lightened flywheel is a solid peice and thats probably what you had since it rattled

here is a run down on the pros & cons:

The dual mass systems are designed to transmit less engine vibration to the driveline, and give a better more car like driving experience. They also reduce some of the jarring and stress on the transmission and remainder of the drivetrain. They work fine as long as the engine remains unmodified and the vehicle is not used/abused beyond manufacturers recommendations.

As soon as you start to increase the engine power over stock, or load the vehicle beyond design parameters, you run into problems. Dual mass flywheels are tuned systems and must be matched to the engine torque curve, engine resonant characteristics, vehicle load curves (including axle ratio/tire size calculations). They work by having a set of springs inserted between two rotating masses (thus dual mass). The springs are sized to soak up some of the resonant vibration from the diesel engine under load conditions. A dual mass fly wheel generally also contains an over torque friction release, so if it gets suddenly overloaded, rather than damage the springs, it slips. This works fine as a safety valve, but if it does it much it burns up. In short, overloaded they burn up and the springs get destroyed and they are worse than if it were a single mass FW.

The single mass part WILL tend to transmit more engine pulse (vibration) tot he drivetrain, and will seem a bit rougher. But it is straight forward to design a single mass flywheel and clutch package for pretty much any engine torque curve and vehicle loading combo you can come up with. Drives more like a TRUCK, but has much better reliability at extreme use levels.

Depending on what you have done to your engine and how you use and load your truck, we can supply a single mass flywheel and clutch system properly sized for your truck. Ballpark $600 for a mildly massaged engine, more for extreme applications.
