I think you will find that the thrust bearing can be replaced.Look and the bearing in the pic,not the brass spigiot bush,you normaly get one with a new clutch.
My Sport Comp Autometer boost gauge needle sits between 0 and 1psi when off.
The gauge was off my cousins VL turbo and he had a wolf 3D wich tells you boost on the hand peice,both shown the same boost so I guess thats the same as yours.
