at first it was upto 2000, but yesterday when I took the video and tried to replicate the sound I noticed it would still do it on higher RPM. I *believe* the small turbo is upto 2000 RPM, and that's when the larger turbo kicks in. I could be wrong tho. That's why originally, I thought it was a high pressure (small turbo) bearing issue.
I'm hoping it's not a turbo issue as I'd probably want to replace both. (if 1 is failing, the other may not be too far behind) which would be quite the job. Replacing the lower turbo looks like 15hr book time for labour. 4.x hours for the small turbo. + the cost for all the parts.
When it does squeel, its only for a second or 2 as you can hear in the vid.
