Hey guys,

I recently put a heavy duty button clutch into my car last weekend, and am playing on taking it to an event this coming weekend.

I've been driving it as much as possible, but is there a quick way to bed the clutch in?

I have a 3hr drive to the track tomorrow night but it is mostly freeway. Should I consider pushing the clutch in and out occasionally as I drive? Change between more frequently 4th and 5th? Or am I going to do more harm than good?

Thanks.

I would have thought a couple of days of driving in city/traffic sufficient. After a 100 or so kms again I would think all is sweet.

PS. Stay away from riding it for a short while immediately after fitted. Being a button clutch if you ride it will heat up the button easily.

Glazing can occur also.

In my last car (R31, RB30 engine, RB20DET box) I took my car drifting and was used the clutch as I normally would after a couple hundred KM of normal driving, no problems at all. I just did the same thing with my S14 (SR20 engine, RB25DET box) with no issues - it's all you need imo!
First clutch was an Exedy sprung brass button with an upped (1350kg) clamp load job, S14 clutch is an Exedy Sports Organic (coppermix-ish one).

I didn't smell either of my clutches when bedding them in, I wound out 2nd gear to redline in my S14 with about 70km on the clutch too.

i got npc cushion button clutch rated 450kw.. what was your clutch and your power?

i been told it is normal so lets hope so gonna get a flogging soon hahaha

My current clutch is an Exedy Sports Organic HD - it's silver, not pink like many other Exedy clutches and has a coppermix sort of compound - like a poor man's Nismo Coppermix haha.
My power is dead stock, SR20DET.

My previous clutch was a bit of a mix, it was a 6 puck sprung brass button clutch (Exedy) but K&B Clutch Engineering in Sydney modified the pressure plate and increased the clamp load to around 1300kg. That was used with a stock RB30E, no smell either.


Both very low power applications.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.
