I inspected the turbos a very short time ago and they were okay. Shaft play was within spec and they spun freely with no problems. I will inspect them again though just to make sure. It seems as though the wastegate was my boost issue, and one of the transmission plates that are used as a spacer for the engine and transmission had a bend in it and was possible rubbing the back of the flywheel which would explain the noise being heard in the video.
