2007 Subaru Impreza STI turbo rebuild IHI VF43

This is an IHI VF43 turbocharger removed from a 2007 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. This IHI turbo, like most, suffer from a crack in the wastegate valve are of the turbine housing. 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.

Correct turbocharger installation procedure is extremely important for proper operation and life of the product. Majority of Subaru turbocharger failures can be traced to a clogged union bolt filter in the turbo oil feed line. We provide a new union bolt/filter and turbo oil drain gasket at no charge with every Subaru turbo rebuild service. We strive to offer exceptional service and concise solution to our customers.
