Turbo exducer or inducer are hitting the housing.
If you can gently get the tube off the upper part of the rubber elbow ( inlet to the turbo ) you can get your fingers down there and spin the axle of the turbo and check for axial / radial play. My guess is there is significant movement allowing the inducer ( impeller ) to rub on the housing.
