shnaped_second Posted November 6, 2006 Share Posted November 6, 2006 If it isnt affecting boost or power dramatically, it would most likely be a exhaust leak from manifold to turbo, seen it happen plenty of times...

HR31_RB20DET Posted November 7, 2006 Share Posted November 7, 2006 That or bearings are about farked. My stock turbo sounded like a cop siren on boost, bearings were gone and the compressor wheel was grinding on the housing.

barnoon Posted November 7, 2006 Share Posted November 7, 2006 I had a very similar problem recently where my turbo was making a really high pitched squeel whenever it got above 11psi, I checked the bolts holding it to the manifold and I could literally undo them with my fingers! Did them up nice and tight and now the noise has gone away completely so check your bolts and gaskets first Link to comment https://www.sau.com.au/forums/topic/142002-turbo-making-weirrrrdd-noises/#findComment-2648769 Share on other sites More sharing options...
rami Posted November 11, 2006 Author Share Posted November 11, 2006 thanks for all the replies... i am running stock boost.. and once i put my foot down the noise goes n comes.. but as it is building boost it makes a bit of noise.. AND this only happens when the cars fully warmed up.... my computers been stuffed and ive had no time to take it to a mechanic.. hope its nothing major.. i doubt it would be the turbo manifold with a hole.. i replaced it not long ago.. maybe the exhaust manifold?

str8g Posted November 11, 2006 Share Posted November 11, 2006 Its probably your gasket between the turbo and the exhaust, I had the same problem. i thought it was my turbo so I went and bought a stock turbo. I found out that my old turbo was ok but the gasket was worn out and the turbo housing had cracks..

Fry_33 Posted November 11, 2006 Share Posted November 11, 2006 I am getting a high pitched whirring noise near max boost (10psi) as well.. was thinking about posting a question about it so this saved me i guess. I guess I'll be checking the turbo - manifold gasket and maybe its worth researching a new turbo at the same time. Does anyone have some rough prices for some of the various turbos for an R33 GTST? GT-RS, GT2530 etc? just thought it'd save me some time. I'd be looking for something of similar size to the standard one.. the less lag the better. I may just even get a standard one I'm not looking for max power figures. Any info greatly appreciated Cheers Link to comment https://www.sau.com.au/forums/topic/142002-turbo-making-weirrrrdd-noises/#findComment-2662893 Share on other sites More sharing options...
Primordial Posted November 11, 2006 Share Posted November 11, 2006 yep... i had the same problem... it turned out to be the exhaust gasket... Get it checked out. I think you've had enough suggestions on the source of the noise to at least get the exhaust gasket checked out.
