I wouldn't rebuild it myself, but there is a great Turbo re builder in North Jersey that will essentially blueprint it back to new as long as the main casing is still intact...$389
Standard Turbo Rebuild Cost = $389.00, entry level price covers automotive turbochargers only.
Complete tear-down and inspection - turbos we receive are identified, marked, and dis-assembled to component level. Each part is thouroghly inspected for wear and/or damage, and any cause of failure is identified so that it can be corrected prior to re-installation.
Cleaning and Media blasting - Turbine and compressor housings, bearing housing, and turbine wheel are stripped and refinished. If your housings are specially coated, we clean them with solvents to avoid damage to the coating. The bearing housing is refinished, flushed with solvent and precision honed before being cleaned, and the turbine shaft is polished to a mirror finish.
Component Blueprinting - Journal bearing bores are honed and sized to ensure proper for oil clearance. All parts and components are checked and verified against manufacturers specifications to ensure they are within limits.
Component Assembly - Turbo is reassembled with new journal and thrust bearings, o-rings, piston rings, fasteners, thrust collars, and seal plates.
High Speed Balancing - All rotating components, aka: "the stack" are double plane balanced as individual parts prior to assembly. After the Center Housing Rotating Assembly is assembled the CHRA is Vibration Sorted (VSR) to less than 1.5G at 100,000RPM. Each turbocharger is tested in a real-time as if it were on the engine, our simulator allows for zero error and 100% customer satisfaction.
