Probably exhaust manifold Gasket.

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 :)

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?

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.. :(

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

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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
