Turbo Wows

[Robyn Psycho bitch]

Hi all I have a s1 stagea 1997 with a rb25det engine

It has developed a wine from about 2000 rpm up it sounds like the turbo..... its a high pitched wine

and gets worse as the rpm rises but when it is backed off it reduces in loudness buy when you rev it the wine follows the rpm

still drive-able but the wine is very loud

any ideas ?

or does anyone want to buy a stagea s1 about 265,000 km fair condition

2 months rego $3000 firm

regards Robyn

The one could be a pulley on the motor or an idler, if the whine is consistent while revving with the whine while putting the engine under load it most likely won't be the turbo. Have the car running and stick your head under the bonnet amd pull the throttle cable a few times to try and pinpoint where the noise is coming from

Location?

Could be an air leak - does it start when the turbo starts to produce boost?

hi

the noise only starts when the motor is warm .... it isnt there at idle comes in at about 2000 rpm ... I dropped all the belts and its still there.... I took the heat shield of the turbo and the noise changed ...

I dont know too much about these things only what I learn on these forums .....I am 60 year old girl that likes import cars

I am near Taree nsw...

Very unsure if srs

Much worry

Plz run car with belts on

Wow

Perhaps bottle the wine & make profit?

A wine with a delicate flavour and slight overtones of unburned fuel.

Spam or not it sounds like an exhaust manifold leak at the turbo or the head. Check for leaks and check if fasteners are tight or broken.

[Daleo]

Normally exhaust leaks are more apparent when the engine is cooler; as things expand they tend to shut up.

^ Not always. Opposite can happen...

On my 220,000+km the exhaust gaskets on the rb25 went and it was similar, but basically all around noisey. Just more noise with more load. Might be worth checking the exhaust gaskets or ask an exhaust workshop to check them. The gaskets themselves are cheap, but a bit of labour

^^another for exhaust manifold gasket

[AngryRB]

+1 for exhaust leak, Id be expecting a few broken studs in the head and a warped exhaust manifold face, maybe some shaft play in turbo too.

could also be some noisey pulley bearings and belts

i had a cracked exhaust manifold which looked pirfectly fine, took it off and stressed it open and it was about 3inches long.

Hi

I started to remove the turbo and I found a heap of oil in the pipes.....

and I have about 3mm end play in the turbo....

I need a cheap stock turbo......

I only want to sell the car
