Turbo Making strange noises

[Soup Nazi]

I searched loking for info on this. A lot of people on here have had blown turbo's so i'd figured i'd find something, but i did not.

I have no oil leaks anywhere.Car does not smoke at ALL. Just the other day the turbo started making very stranges noises. When im driving normally not hitting boost, there is no strange sound. As soon as i accelerate harder, then the turbo starts to sound like it's Squealing/screeching. Very odd. It does not sound like it use to when it was spooling before.

It's got to be the turbo, everything else is sound. It only make this noise apon spool up.

Any thought's guys?
