Hi everyone, I am currently getting my A15 motor worked and would like to know what type of clutches people use on these motors?
The motor won't be a racing motor, but something that is for the street.
It will have a mild cam, shaved head, electronic ignition, bored out slightly, port n polished, weber 32/36, extractors, bigger valves and maybe flat top pistons.

I have bought a standard pbr clutch, but now I am thinking I may change that for an Exedy heavy duty clutch, as I don't want to pull out the gearbox as the pbr isn't up to the job. (not strong enough)

Please let me know what clutch you run in your A15.
Cheers.

I got mine made up by a clutch shop. Couldn't find an of the shelf item heavy enough. Only around 200bucks. Never slips, chirps 3rd etc so im happy. Thats on standard size of 180mm.

Next option would be give them your flywheel and they redrill it to suit 200mm clutch plate. That way you get grip from extra surface area and can keep a reasonably light pedal.

I have bought the Exedy Heavy duty unit. I havent tried it yet, but it should keep up.

and the best part is that it comes in a fluro pink box!

Make sure you get an A15 pressure plate (clutch cover). That is more important than the clutch disk. The A15 pressure plate is stronger than A12 pressure plate.

Thanks for your reply's.

The pbr clutch kit that I have bought for the A15 motor is the same part number for A14 and A12 motors

I would think that that A15 would of been a different kit, being a more powerful motor.
It lists a different part number for A15 on the clutch industries website (R169n)
and the A14 and A12 are the same kit (R137n).
I bought it from Burson Auto Parts and the R169n kit was listed for the A15 vanette motor, but they said the R169n clutch kit tranfers to the R137n kit

So to play it safe I might just go for a heavy duty exedy clutch kit.

When you get the flywheel lightened and machined, get them to increase the 'step' to give you a bit more clamping force again. . .

Originally, the A12/14/15 engines all had a different clutch. They were essentially the same except for clamping force, but in the parts industry there is little sense in keeping three or more different part numbers for three or more clutches that all interchange.

Better to delete the weaker ones & carry one part that services everything, so whenever that is possible, that's the way they usually go.
With only one part, there is no possibility that Mr A15 ends up with an A12 clutch by accident, so no unhappy customers, the retailer needs to cary as little as a single part on his shelf to service everyone & the clutch manufacturer simplifies his product range too.

Clutches for commercial models are often the heaviest duty versions.

Back when I was a young bloke, my girlfriends family had a 1963 Toyota Tiara that they had bought new. The girls in the family had a nasty habbit of riding & slipping the clutch around corners instead of shifting down & it had been replaced twice by 1968.
I came along when the second replacement died, so I fitted a new one for a Toyota Dyna 1900 truck. The clutch pedal felt like a brake pedal & needed a leg like Arnies to hold it in.
It was never slipped again, .... ever.

Yes, a lot of aftermarket clutch kits for A12 are really the A15 type.

The original Nissan clutch has a super-light action. It's a dream.

Most 1200s i've driven the clutch pedal was much much heavier.

The Micra Turbo clutch is the one they favor in Japan. I understand it is the heaviest duty one Nissan made of that size (fits a 1200).

nismo i can confirm that it is the same situation with the pressure plates for the excedy mob, i personally rang them up (one of the beautys of working for an auto parts store) and the dude told me that the vannette a15 clutch uses the same clutch as the a12 and also that the a15 pressure plate number cross references back to the a12 number. i went all through this looking for a clutch for my a15 race motor, which turns out, when i pulled the old one out it had an excedy clutch plate and a pbr pressure plate???

In my racecar i'm using a PBR rpm pressure plate (the yellow ones), which is their heavy duty model or something. When I was running the 60 series I used a standard clutch plate that I prised off a rusty old engine out in the paddock with a screwdriver, it worked a treat and didn't slip in one and a half seasons of supersprints/hillclimbs. Now i'm using an organic sprung center exedy item with the same pressure plate for the toyota gearbox and it's holding up quite well.
