Hellooooo all
My Evo 9 GSR is almost stock, lately when the turbo spools and gets up to 1.2bar a high pitch whining noise would appear from the turbo, it keeps whining until I change gear or so

What is happening? Is my turbo about to go?

 

if it sounds like a dentist drill thats usually when there about to go. or there could possibly be a leak somewhere

 

Oh just as I thought ... so I guess I can start looking for a new one and wait till it dies

 

well id start with a boost leak test first and see if you have any leaks. you dont wanna jump right to buying a new turbo and putting it on then having the same sound ya know

 

Check your intercooler piping and your BOV seals. I have heard some pretty wicked whines from bad seals. Hopefully its not the turbo.

 

x2. I had a nasty leak at a BOV that made some weird sounds. A boost leak found a small chunk of the gasket missing that you could not see from a visual inspection.
