I'd just like to say 'Hi' from a new WGNC34 RS-Four owner :)

I'm no stranger to (turbo) Nissans, owning a L28 Turbo 240Z, DR30 RS-X Turbo Skyline & now the RS-Four. My sister owns a GTi-R, and my dad has a 240Z (RB25DE), 1500 Fairlady, 2-door LHD 510 (VG30ET) & a original-owner 510 (FJ20E).

Some of you may know me from Ozdat, or if you're into the 'Z' family, HybridZ, ClassicZcars, or the IZCC mailing list (among others).

I've had my eye on the Stagea ever since Viper Motorsports had one here in Adelaide a few years back. Recently I made the decision to save my DR30 from the daily grind & get something a little more 'practical' while still maintaining pedigree. Enter the Stagea....

Only had it a few days, but must say it's a beauty. VERY impressed.

I have (had?) a couple of queries:

1. The diff control button on the dash - explained in another thread. Too easy!

2. My car has another switch adjacent the diff control labelled 'Light Reduce'. Anyone know what 'light' it 'reduces'?

3. The momentry action switch on the drivers side of the dash - is it side-window demist?

4. There is a slight 'click' that appears to be coming from the rear-right of the car just as the vehicle starts to move, sometimes a couple of clicks. Something is loose, the click is not loud, but it does occur in reverse & drive but ONLY as the car starts moving. If you let the car creep & then accelerate (gently), it does not happen. It cannot be heard with the windows up, but when down it is quite audible.

I suspect it's the brake pads moving in the caliper, which I shall investigate in the very near future. Other threads have suggested everything from wheel bearings to tailshaft joints & everything in between. So it seems that everyone's cause is different (as would be the noise).

Aside from that, it drives like a dream.

I figured it was something to do with the automatic linkages/controls. I've never looked to even see if they we external even. Didn't really concern me as a big problem, one day it would just stop and then I might find out? "Oh.... so thats what the noise was" general response and then fix it.

Ok people, I think I've narrowed down the cause of the 'clicking' coming from the rear of the car (left & right it seems)....

Examining the wheel area when moving the car under power reveals 2 things:

1. The pads move in the caliper (as suspected).

2. The caliper flexes on the caliper pins.

I believe that the latter is the cause of the noise - the friend who helped me on this reported that his rally car (fitted with R30 discs/calipers) used to make the same noise. There was NO WAY it was bearings/mounts/bushes/diff on his car & I have thouroughly inspected my car & discovered no loose or noisy components.

So, my thoughts are to possibly fit replace the factory sliding calipers with some R33 2-spots (and perhaps fit 4-spots on the front).

Are the rear (and front) discs compatible? And has anyone else fitted GTS25t brakes to their C34?

PS - I've also got a translated owners manual on the way, which should explain the 'light reduce' function. The switch on the right side of the column is also most likely the side-mirror de-ice controls.

    • Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.  
    • Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly
    • oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)
    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
