I've had a few inquiries about getting it done and costs. Well first of all its not a simple bearing kit that drops in. To make it work we will need to grind down the turbine shaft, bore out the bearing housing, make up custom bearing collars, insert BB cartridges, assemble and balance the core. High precision engineering is time consuming work plus the cost of two high speed ceramic ball bearings cartridges its not a cheap procedure. But having said that this service can be carried out to range of mid / large size BorgWarner turbos, and it does increase the throttle response by quite a bit after bearing conversion.
