Abstract: A turbocharger assembly can include a center housing; a turbine housing; and an insert disposed between the center housing and the turbine housing where a surface of the turbine housing and a first surface of the insert define a volute and where a surface of the center housing and a second surface of the insert define a chamber.

Abstract: An assembly for a turbocharger can include a shaft and turbine wheel assembly and a component that has a rotational axis and that includes a through bore for receipt of the component by the shaft of the shaft and turbine wheel assembly where the component includes an inner surface and an outer surface and one or more passages that extend between the inner surface and the outer surface, where the one or more passages are shaped to exert force on the component responsive to flow of fluid in the one or more passages and where the force rotates the component about the rotational axis. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Abstract: An assembly can include a compressor backplate; a bearing boss that extends axially from the compressor backplate and that includes an outer surface and male coupling features disposed along the outer surface; and a casing that includes a compressor end, a bearing boss opening at the compressor end, a turbine end, an inner surface located between the compressor end and the turbine end and female coupling features disposed along a portion of the inner surface, the male coupling features and the female coupling features configured to couple the bearing boss to the casing. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Abstract: A system can include a turbine housing that defines a turbine wheel space, an exhaust chamber in fluid communication with the turbine wheel space and a control shaft bore that extends from the exhaust chamber to an outer surface of the turbine housing; a blunt body positionable above the turbine wheel space where the blunt body includes an opening and a lumen in fluid communication with the opening; and a suction conduit connectable for fluid communication between the control shaft bore of the turbine housing and the lumen of the blunt body. Various other examples of devices, assemblies, systems, and methods are also disclosed.
