Hey guys,

Hope someone can help with a noise that's recently started up... Sort of a "zzzzz" noise, seems to be in second and third gears mostly (maybe just can't hear it at higher speed), but I think I've heard it in 1st before as well. Was thinking turbo, as odo reads 216000km and I've had it since 14000 without replacing it. No oil in the inlet pipes however... Definately seems to be coming from under the bonnet as I can't hear it with the windows up. Doesn't do it free reving. Seems to do it only when warmed up. When it starts making the noise, it goes away immediately as I accelerate.... haven't been booting it too hard since it started though... Please, has anyone got any ideas or tests I could carry out (short of removing the turbo, yet).... :(

Ive got the same noise In my GTR and had it on my gts-t. The noise comes from the gearbox and ive just put it down to my rattly old twin plate

you only get it at low engine speeds right?

Only prob is I don't have a twin plate... stock rb20det with unknown clutch... been in for the 75000km I've owned the car. I thought it might have been the gearbox too, but I can hear the box throught the trans tunnel and it doesn't seem to be coming from there... tried some nulon g70 in it to see if it would help but no change... only started less than 1000ks ago...

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
