A turbocharger having a sliding piston assembly comprising a tubular piston disposed in the bore of the turbine housing such that the piston is axially slidable relative to the turbine housing. The piston assembly further comprises a tubular carrier inserted axially into the bore of the turbine housing surrounding the piston and fixed against axial movement relative to the turbine housing, a radially outer surface of the carrier engaging an inner surface of the bore and a radially inner surface of the carrier being slidably engaged by a radially outer surface of the piston. The carrier defines an axial split extending a length of the carrier, and the carrier is resiliently flexible. Accordingly, the axial split allows the carrier to expand and contract in diameter.
