Whinning Noise From Turbo

[FLIBYUGSR12psi]

Hey All

I fixed all my problems and the car was running great for aboout 2 dayz

i was driving it yesterday and now it makes a huge whining noise in the turbo. noise the air sucking noise like a loud whines, and it does not boost at all?

its like the air isnt goint through the turbo.

Any Ideas? Also thre is not smoke

It is an r 32 turbo, if i seem to be f$%ked i will replace with an r33 turbo, so if anyone has one goin for cheap let me know please.

all I can say is, take the intake piping off, and check your shaft play.

Sounds like its finally given up.

Are you sure it's not one of your intercooler hoses leaking?

Found the problem.

Pulled the turbo off and found 3 of the teethe on the exuast side ( the wheel ) where stuffed.

I am now opting for a r33 turbo. I would go high flowed or someting with a litle bit more power but the car might be getting sold soon.

Thanks for all da help.

P.s I assume the r33 turbo had ceramic parts as the r32 does? ( I have now learnt why people go for steel parts.)
