This is a custom turbo we built for a customer in Pennsylvania. This project started with a damaged ball bearing Garrett T28 turbocharger. Since the turbo cannot be serviced or rebuilt we converted it to journal bearing system. We build these turbos usually with a more popular 0.64A/R turbine housing. This time the customer requested a bigger turbine rotor shaft and turbine housing to better suit his performance-oriented needs. All machining was performed like a standard Journal Bearing Conversion with the exception of additional machining of the wastegate mount on the compressor housing.
