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...

      Yeah - Half the problem is I know this sensor actually goes to 150C.. I'm pretty certain it is min of 11C. So still more data required I suppose. It's really quite hard to get the oil temp to 100+ then immediately pull over and take a reading before the temp drops. Annoyingly I suppose the range I really 'want' is likely 80 -> 120C. TBH the ecu can't really *do* anything with it, and the gauge itself is very visible... ...but you know how it is.

      My EFR 8474 Black, made 800awhp on a roller dyno. at 25-26psi. E85. Shaft speed was around 106,000rpm 1.01 rear. The rear is maxed.  6 boost Turbosmart 60mm gate 3.5inch exhaust  Head is worked to the shithouse. Bain racing. VCam. 272 exhaust. RB28 - RB26 foundation.  You have an intake issue. Start getting proper data and I mean go back to the simple things.  - Pressure test your intake - Block off the Turbo BOV, you don't need it.  - Test pressure before and after your intercooler If your head is pretty stock, that is your issue. Especially if it is NA.  Take it off and spend $10k on it.

      Temp = -21.052 X Voltage + 114   That should get you pretty close. Calcs based on two points I could do easy calcs on (30 and 70 degrees).   It also says your sensor should only read as low as 9 degrees when it maxes out at 5V, and should hit a peak of 114 degrees at 0V... Just as a heads up if you were going really cold places, or wanting to be aware when temps really go up with it.
