Ok I have a minor problem. I have a pulsing vibration. Similar to when a uni goes. It can be seen throught the shifter in 3rd and felt through the car in 3rd, 4th, 5th and 6th. Has anyone come across this or similar problems before. I heading to get the wheels balanced and wheel alignment checked tomorrow. Car has Only 56 000km's on it.

Ok wheel alignment was done today. But has made no difference. The vibration is still there. The revs stay the same while driving . Revs do fluctuate at idle though. I'm thinking it's between the g/box and the diff. As it can be felt through the seat while driving and seen through the shifter but only when in 3rd.

What a decent workshop in Bris that know there shit when it comes to Gtr's

Yeah shifter moves back and forth slightly not sure on clicking sound at all

If you go slowly in 2nd or 3rd and then accelerate and then decelerate and then repeat the cycle, is there any clicking sound, or sudden movement in the shifter?

If there's vibrations going on whilst at constant speeds whilst cruising, I suspect tailshaft

If there's clicking at low speeds on accel/decel cycles I suspect diff oil needs changing

If there's a lot of movement in the gear lever with vibrations, I'm wondering about bushes/springs too

You've got a good Brissy mechanic?

Yeah not sure i've only had the car a week. Does anyone know of any decent mechanics?

U can notice the shifter vibrate in 3rd the most. Do the tailshafts fail? Would it be the centre bearing?

You running stock rims, or rims with the same rolling diameter & width at all corners?? I heard that different profile tyres & different width rims could cause problems with the awd system on earlier gtr's. Just a quick check. After that, +1 for the possible tailshaft culprate.

      Who has a Infiniti Q60, Q50 (V37)?

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
