BO3 Turbo Rebuild Kit - N55 Turbo Service for BMW — Overview

This is a basic rebuild kit for a BO3 turbo used on BMW N55 setups. If you are tearing down a worn turbo to address seals, bearings, or shaft play, this is the service kit side of the job rather than a performance upgrade. For BMWs, the key thing is matching the exact turbo model on the car, not just the engine family, because N55 turbo hardware can vary by application.

I would pick this if your compressor and turbine housings are still usable and you are comfortable measuring clearances during assembly. If the wheel or shaft is damaged, or the CHRA is questionable, a complete cartridge usually makes more sense and saves time. On a G80 fitment listing, I would verify the actual turbo and engine setup before ordering, since G80 is not a normal N55 application.
