R32 Gts-t Diff, Is It Viscous? If So Shimming?

Is the R200 shortnose a viscous or clutch type diff in the R32 GTS-Ts?

Reason I ask is mine is opening up pretty bad and makes it quite unpredictable to drive. If it is viscous would adding more preload via wider diff shims be of any benefit? Or will it just make it harder to open up but will still be the same on full power?

Can the viscous oil be changed to something thicker?

If not guess I'll be looking for a nismo 1.5 way or something, wouldn't mind a cheap fix in the time being though. Only have 200kw and cant put it down in 1st or 2nd.

Posted it in the other thread but I will post it in here as well:

Has anyone considered changing the actual viscous fluid in the LSD centre? As changing the preload is really just a tightass hack that won't really work that well. It either locks or open wheels sort of thing, no middle ground where its like 50% locked. The only time you could achieve the nice medium is if your diff was still in good condition and not completely open wheeling.

I've heard of people putting thicker fluid in the viscous centre in 300zx's etc so surely it can be done here, is the centre serviceable, like can it be unbolted and pulled apart? If so it would just be a matter of finding out what fluid is currently in there and replacing it with something thicker.

Anyway let me know if anyone has done this before or knows if the oil can even be changed.

edit: Perhaps I am wrong but I am assuming that the diff centre is sealed and uses a different oil to the actual diff crown and pinion, if not could we just experiment with putting thicker oil in the diff itself? Would make the car slightly more sluggish, but might make a big difference.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By Duncan · Posted

      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.
