A turbine housing of a turbocharge can include a surface that defines a portion of a volute, an annular surface that extends radially inwardly to define a portion of a pressure chamber that is in fluid communication with the volute, a substantially annular plate that defines a portion of the pressure chamber, an annular component, at least one spacer that defines a minimum axial distance between the substantially annular plate and the annular component to define a nozzle that is in fluid communication with the volute and in fluid communication with a turbine wheel space where, responsive to fluid flow in the volute and through the nozzle to the turbine wheel space, the pressure chamber has a fluid pressure that exceeds a fluid pressure of the nozzle to apply a biasing force to the substantially annular plate in an axial direction toward a center housing.
