Garrett T28 turbo rebuild and journal bearing conversion 0.86A/R

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.

    Hey, I have a lot of brand new journal turbochargers in all types of sizes and wanted to know. If I want to keep them as a journal type and just get te cheap stuff replaced with better parts like; let’s say the typical (weak) turbine center stem piece (that always breaks with cheaper units) and also get everything else remeasured and checked out….. How much $ would you guys charge and I only need a RANGE….. And everything up to 88mm journals……..734-642-6317 BENNETT, hugh
