Well GTST25 was correct I looked at the turbo and it was only being held on by two nuts and they where loose also put two more nuts on and made sure they where on tight this time and she is all good :(

PS Does anybody know anything to stop this from happening again?

I know its cheap to get more nuts but I dont really want to keep replacing them every 3 or so months

something just happened to my turbo on my r33. When engine is revved and boost is starting to build up it makes a screaming noise, sounds something like an external gate. Its loud, sounds alright but i doubt it can be good for the turbo, took the intake pipe off, very very little shaft play back and fourth and turbo spins perfect, very free spinning also no chips on blades.

My 32GTR has a whistle noise all the time from 800 rpm to redline. I can hear it through the centre vents. I think it's from the Turbs but I cant determine what it is if its not even spooling (r34 N1's). Mech thinks the front turbo has a problem.

Like another post I'm going to wait until something drastic happens but sure would like to know for certain what it is.

PS. the engine has just been rebuilt - it was there before and it's there now.

i have the same high pitched noise coming from my car

it comes around from the turbo area side but im not sure when u listen close up it sounds like the other side

couple of people told me its normal and its possibly the powersteering pump

i just checked the 4 bolts and locktabs on the turbo and they are very tight.. im guessing its powersteering pump that needs replacing or its just normal and im getting paranoid :D

my noise happens when the car is warm, after a decent boost, then at idle you hear it whining and when you rev to 1500-2000rpm the whinding goes louder, but then u take it for a drive again and it disappears, then comes back and then disappears.. not to sure what to expect

anyone else had this and replaced powersteering pump?

Tiesto:

Do you have a front mount?

A mate of mine has a 4 door R32 and it made a noise like that turned out to be the Air passing through the Intercooler Pipes

LTHLRB:

I wouldnt because if the tubo is just hanging off you could make the turbo worse thats what Ive been told by Turbotech.

Sinister32:

I know what you mean can fix whats not broke right?

Mate i had a nasty squeal from my engine bay once. Couldn't find a boost leak, bad belt or anything. Then i realised i had some broken exhaust studs, started to fix these and realised the the turbo had come loose from the manifold (no idea why ??? bought the motor from a wrecker in sydney had it fitted by a mechanic) and the squealing noise was the pressure coming out from between the join. Long story short removed the turbo replaced the gasket and bolted it back together and wala :(. This noise was only on 3/4 to full throttle. Went heaps better after that, no shit :P haha

I have this one, my mechanic has explained the whine to me a while ago and ive kinda forgotten what he said, but something about the cams have now become worn in and its getting stuck doing its variable valve business when its idleing... Nothing to worry about he recons.

Worst explaination... ever.

well that might explain it cheers mr italy, i might get someone to take a look at it

ive also noticed that on my exhaust manifold there was a snapped stud (the last stud which is closest to the firewall), and the nut and half the stud fell out today upon further inspection... so now the other half of the stud is in there, i plan to fix that asap but i doubt its related as i dont have a exhaust leak, just a whining sound >_<

yer I have a stud missing from the man when I was changing the turbo back last year, When I removed the heat shield the nut and half the bolt fell off, I was like dam better fix that but doesnt seem to have made a dif so meh.

There are a few things this that makes noises that the f**king shitty thing you have to just try and go through the list until its gone :blush: at least you know most of the part that where replaced are new lol.

  • 1 year later...
mine does exactly the same started doing it once i put on a pod so im guessing its because of the way the air goes through the pod at that particular point causes a whistle its definatly not a problem or because anything is shagged and i wouldnt be doin any major component changes to fix it

Ahh! What is this noise (rb25 r34) Loose bolts turbo? Yep! Did them up, Ahh! Still there, Hint: does it on idle, tap the accelerator, gone?? Hard to find but seems to be seals on throttle motor (tract control) when engine is finally hot and under vacume there's that squeely noise. Anyone had this one before??? Cars done 94000klms just started. Those Whitty People with the flashy lights pulled us over "Whats under there mate a dead Cat" HA HA didnt even know what he was looking at any way. $79 Part of 2007 Label still affixed (I was going to scratch it off eventually), $200 Didnt like My HKS Induction.

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
