R32 Gtr - Transmission Problems

Hey all,

I was wondering if anyone could give me any insight into what may be the problem with my r32 gtr.

I was driving it over the weekend and it started making a loud knocking sound which sounded like it was coming from around the middle of the car. The sound appeared after driving the car normally (wasn't booting it) and it would increase in frequency the quicker I was driving. After pulling over the sound would stop and it wouldnt make any noise from just revving the car.. Only when I was rolling or moving...

So after this I started to head home about 5 mins later the sound disappeared.. After driving the car since this happened I havent heard the sound again.. Anyone have any ideas on what this might be? I was thinking uni joints but I am probly way off..

Cheers,

Mitch.

Yea, sound was happening whether clutch was pushed in or out.

Just seems weird, I have been driving car for days now since sound occured (happened on Saturday) and it hasnt re occured at all, I am just a little worried as it was a very loud noise so obviously something is wrong, just dont know where to look.

So it was only making the noise while the car was moving??

Didnt matter if the clutch was in or out??

The noise changed as the speed got greater or less??

The noise stopped when you stopped moving??

Sounds like you may have picked up some crap in your tyres or possibly got something caught in the driveshaft that has since parted company with your vehicle if the noise is no longer present.

this is a great trick in the workshops... Wack a rubber band around the tailshaft with a nut on it. As the speed increases the nut flies further from the tailshaft tilll it eventually start "tapping" against stuff. When ya stop and look under the rubber band has contracted and you cant see it on the tailshaft. :P

Yea it was only making the noise whilst moving, didnt matter if clutch was in or out, and the noise sped up as I was moving faster (noise was probly louder when driving slow), noise was there whether in gear or in neutral and rolling and yes noise completely stopped whilst I was not moving.

I once had had a screwed diff / uni's in my old car and the noise was much like that, although it didnt sound like this noise was coming from as far back as the diff...

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
