Another common turbo we rebuild at PRE. This is a stock CT26 found on the MK3(1986-1992) Toyota Supra. This turbo showed its age when we received it. Worn compressor wheel with chips and bents, excessive wear of the bearing housing, and typical cracks in the turbine housing inlet and wastegate opening. We did a complete restoration on this turbocharger. new compressor wheel, micro-polished turbine rotor shaft, all new bearings, seals, o-rings, and of course, balancing of the rotating assembly. Bearing housing was worn out due to age and possible oil starvation. We honed out the housing to the next size journal bearing. With the exception of bearing housing honing this turbo qualified for our Basic Turbo Rebuild process.
