Subaru Impreza STI IHI VF39 Turbo Rebuild

This is an IHI VF39 turbocharger removed from a 2005 Subaru Impreza STI. The turbo was in decent condition to begin with and only needed a complete rebuild kit for the overhaul. Customer complained of minor oil consumption and smoking from the exhaust pipe. Inspection revealed a worn out turbine shaft seal. Complete rebuild was chosen as a solution. If you are already this far in the process why only replace one seal? We replaced all components to make this turbo 100% new. We disassembled the turbo, cleaned all components, and inspected everything. Surprising this turbo did not have the typical wastegate crack in the turbine housing. WOW! After complete inspection bearing clearances were checked using Mitutoyo micrometer and bore gauge. All clearances were within factory specification. Turbocharger rotor shaft assembly was balanced using a Schenck balancing system. This turbo is a perfect example of Basic Turbo Rebuild Service we offer.
