wire wheel…whaddy ya think this place is ;). It’ll get the usual overhaul stuff. hot tank + 400 grit blast on turbine housing, soda blast center section and comp housing. Jet wash all other components, surface turbine gaskets. Replace consumables, assemble, balance, box. Like new, good to go. It’s how we roll here 
I’m not going to polish that comp housing. Koch can do that himself if his heart so desires…polishing is for the birds, unless I can do it in the CNC.
