Ive had my RRM turbo on my car for about 25,000 miles and the other day it sttarted making some strange noise. Only when my RPMs go above 3000. It sounds like a screech.
My waste gate also sounds weird when under pressure. My check engine light came on and it read mutlipe missfires and o2 sensor.

Any ideas? Does my turbo need a rebuild?

You might want to contact RRM on that issue. A video of what's going on will help too.

pull the plugs and make sure they are still intact. Also pull the intake off and check the compressor wheel for play because it sounds like your wheel is hitting the housing which would mean you need a rebuild

Could be the turbo bearings. I had an Eclipse do the same thing. Sounded like the poor thing was screaming for help.
