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...

    • On the compressor side it looks like the best, if your head setup will support doing 100-110lb/min at 30psi-ish boost.   The G45-1350 compressor looks ideally better if you need closer to 40psi for it, given both the G40 1150 and G42 1200 look like they'll be around the 100lb/min mark at 35psi and dropping from there.   Bear in mind the turbine sides are all different between those three turbos, so that COULD be an influencing factor for how they all perform in the real world as well.   Not sure if you've made a conscious decision to only look at Garrett or not, but at least on paper the XRE7169S matches or beats those other three at everything from 30psi up and just going from wheel size alone likely to be at least as responsive as the G40 1150 and seem to behave closer to G42s in terms of turbine flow.
    • @Lithium  looking for a turbo for my Rb30. Want to make sure I understand this correctly.   If I want to stay 40psi or under my best choice of these 3 is actually the smaller G40-1150 ?
    • Massive ups for MTHire also. Could not have done the subframe bushings job without hiring the tool from them. Process was super easy and cost me around 25% of the cost of the tool. If you need a one-time tool to do something, check them out. (Paid for the rental myself, no sponsorship here.)  
    • I'd suggest calling Unigroup, they have a lot of experience with these, access to reliable fabricators etc. Of course it will cost but at least you can trust what they tell you
