A turbocharger turbine wheel can include a hub that includes a rotational axis, a backdisk and a nose, where the rotational axis defines an axial coordinate (z) in a cylindrical coordinate system that includes a radial coordinate (r) and an azimuthal coordinate (Θ) in a direction of intended rotation about the rotational axis; and blades that extend outwardly from the hub, where each of the blades includes a leading edge and a trailing edge, where the leading edge includes a lower axial point defined by a first theta angle and an upper axial point defined by a second theta angle, where the first theta angle is greater than the second theta angle with respect to the direction of intended rotation of the turbine wheel.

A turbocharger can include a housing that includes an interior cavity in fluid communication with a lubricant inlet and a lubricant outlet where, at a compressor side, the interior cavity includes an effective opening at a first axial face that spans an azimuthal angle about an axis of a through bore of the housing; a compressor side plate disposed at least in part in a compressor side recess of the housing; and a lubricant deflector plate disposed between the compressor side plate and the first axial face of the housing where the lubricant deflector plate includes an effective opening that substantially spans the azimuthal angle about the axis and where the lubricant deflector plate defines a seal cavity with respect to a compressor side seal recess of the housing.

A turbocharger can include a center housing; a compressor assembly operatively coupled to the center housing; and a turbine assembly operatively coupled to the center housing, where the center housing includes a bearing boss that includes a bore wall with opposing axial ends that define an axial through bore having opposing axial openings, an oil inlet, an oil outlet, an arcuate oil passage in fluid communication with the oil inlet, an oil passage in fluid communication with the arcuate oil passage and an opening in the bore wall, and an oil drainage passage in fluid communication with the opposing axial openings of the through bore and in fluid communication with the oil outlet.
