Nismo Coppermix Clutch - Single or Dual?

[kTrainHurricane]

Trying to decide which clutch to go with, and would love some input / opinions. I have an S14 with an SR20det + bolt-ons. Right now the car makes around 275 whp, and I don’t really have plans of significantly increasing power anytime soon.

Currently, I have a twin-disc that was installed by the previous owner. It’s exhausting to drive and I feel it’s overkill. I wanted to change the clutch and decided I’m going with a Nismo Coppermix, but can’t decide if I should go single, or dual for ~$500 more.

From what I’ve read, the Coppermix dual doesn’t actually feel like a dual at all. Apparently it’s not much different than stock. I understand that the dual is geared for higher HP cars, but if I’m going through the hassle of changing the clutch anyway, and it should be much easier to live with than my current twin-disc, should I just go for it? Or is it a totally unnecessary waste of $500?

High end dual disc clutches like Nismo, OsGiken, and ORC have a lighter pedal feel than a single disc clutch of the same torque rating.

Since a dual disc doesn't cost that much more i'd recommend investing in it. The Nismo twin coppermix is one of the most popular clutches there is.
Look into the OsGiken TS2BD as well.

Thanks for the input / suggestion!

I?ve seen a few threads talking about the Nismo clutch in Z cars, but none in S cars...not that it probably makes much of a difference 🤷*♂️

My ONLY gripe with the JDM duals (Nismo, Giken, etc) is the distinct twin jingle. With how the center drive and floater plates operate, it sounds like a can of marbles.

Apart from that, drivabiloty is better than any high capacity single plate. However, the single plates have gotten MUCH closer to drivability and have ZERO sound (Spec stage 3+, Spec Stage 3, CM FX500, etc)

Depending on the person the ringle jingle of a twin disc floater is a selling point lol.

+1 for broken car noise is a good thing. not kidding.

Watching some older MCM ( well, the good builds that 'skid factory' does) I saw they used mantic clutches which have some anti-rattle springs. Compelling.

I have an OSG twin on the shelf that I'm going to put in and my biggest reservation is the jingle...

Just realized the OP doesnt want much than 300.

If that's the case, skip the expensive nismo and get the 6 puck white bunny. It will support "500"hp and drive better than stock. And it's only 394....

Dont waste your money on a twin...

I wouldn?t say I ?don?t want? more than 300...that?s just about what the car is making now, and I don?t plan on doing any power mods soon because there are other things I want to take care of first.

I was thinking of going the cheaper route because I figured that any twin was unnecessary, but I was also thinking of ?future-proofing? and didn?t want to be caught wanting to / needing to upgrade the clutch again in 2 years.

Yeah the white bunny will handle any bolt on short of a full power build. I wish the flywheel was lighter
However at the price point, it's up there in my top 3 clutches for a simple build

I've been through a bunch and currently have a ATS twin carbon carbon "baller" clutch so yeah. Been there lol

Keep in mind a twin plate clutch will also be slightly easier on the drivetrain.

I've had used many clutches for customers and my personal sr20det builds. The Nismo Coppermix is the best feeling clutch if you ask me. Add on a Nismo Slave, and steel braid hose and it will feel even better. Light at the pedal, perfect weight, and can take a beating.

My personal daily sr had 376whp and this clutch held up the best compared to other's I've used.

Pro: pedal is slightly firmer than a stock clutch, pedal travel is slightly shorter than stock, no noise, perfect weight (not too light so you won't lose torque) , and soft engagement (great for daily).

I would continue using this clutch on my new set up. But afraid it won't hold. Going to with a twin disc Nismo with my new set up.

*Make sure your using a Factory Nissan or Made In Japan clutch master, or you pedal travel will not feel right*

Thanks for the info! Just to clarify - are you talking about the single or the dual Coppermix?

He has a single coppermix now and is going to upgrade to a twin.

[brndck]

I had a single coppermix and it was def extremely easy to drive
felt like a stock clutch, smooth engagement, easy pedal feel.
I was only about 275-280whp, and it held up just fine.

[RalliartRsX]

I really wouldn't waste your money on a coppermix for a simple build. Get the white bunny 6 puck, don't look back. Its cheap....meets and exceeds your needs.....and is readily available. The flywheel is a little heavy for my taste, but it just downright works

[Kingtal0n]

Its 2020.



I wouldn't run a 4-cylinder without a twin plate after 2020.
jingle jingle all the way I say
