new turbo sounds bad...any suggestions?
I had about 128k on my car when the stock wastegate broke so i had the turbo replaced. The new turbo now makes a buzzing sound, sort of like the dentist drill i have heard described on here. The old turbo had the stock high-pitched whistle. The car has plenty of power and runs fine, any suggestions?

turbo was rebuilt
I purchased a rebuilt turbo from a reputable turbo mechanic. It looked brand new when i received it. The compressor, turbine, shaft and bushings were all new and the housings were rebuilt. i primed the oil system when i finished installing it so i dont think that it could have been installation issues

The K04 I got from you does the same thing...
when it goes from vac to boost. I didn't know it was something to be concerned about -- just thought it was a K04 thing 
Sounds like a dentist drill for sure, kind of cool, actually.

Mine has been doing that for around 25k miles
I don't know what it is. I had a mechanic tell me that the blades could be unbalanced or the one of the wheels could be loose and touching the housing

Hmm...that doesnt sound right. It never sounded like a "drill" for me...
and it wassnt used for very long. I know you have been having issue after issue, but are you 100% sure everything is installed correctly?

Finally, yes. Everything's been triple-checked at this point...
every hose, valve, etc. What else could be causing it to make that noise? It's sounded like this since the first time I drove it.
I might have a little exhaust leak between the test pipe and downpipe, but I don't know if that would be responsible for this.
New gaskets on the manifold side and the test pipe side...
Any ideas?
