BazaR33 Posted July 28, 2005 Share Posted July 28, 2005 Can anyone tell me whats wrong, if anything, with my turbo. It makes a screeching BOV type noise when i hit about 5000rpm. It's a stock R33 GTS-T. Um HELP! Link to comment https://www.sau.com.au/forums/topic/82150-screeching-turbo-please-help/ Share on other sites More sharing options...
Cubes Posted July 28, 2005 Share Posted July 28, 2005 If the the noise can be heard when ever boost (i.e its on full boost by 3000rpm easily) is made I would suggest its an IC piping join leak. As its higher in the RPM (exhaust back pressure in the exhaust manifold) I would suggest a gasket.

SLIPPERY Posted July 28, 2005 Share Posted July 28, 2005 sounds like youve got a boost leak somewhere in the intercooler piping so that it only opens when the boost pressure is strong enough to force an opening. check the silicon/rubber connectors as well as all your piping. may be a split/ loose connection Link to comment https://www.sau.com.au/forums/topic/82150-screeching-turbo-please-help/#findComment-1489637 Share on other sites More sharing options...

gtst25 Posted July 28, 2005 Share Posted July 28, 2005 I had the same screech noise in my old rb20det. Bet it's the exhaust manifold to turbo gasket.
