A turbocharger housing comprises a central housing portion 14 having means 20 for rotatably supporting the turbocharger shaft 22 and a pair of end housing portions 16, 18 adapted to be bolted to the central housing portion 14 at mating annular surfaces of each housing portion. In one advantageous form of the present invention, the end housing portions each include a recessed wall 38, 48 for defining a flow passageway 36, 46 adjacent a radially expanded wall portion of the central housing 14, and a plurality of vanes 42, 52 are integrally formed on each end housing portion to extend outwardly from the recessed wall toward a mating annular surface on the central housing portion. One or more sets of radially spaced mating annular surfaces provides a secure engagement between the end housing portions 16, 18 and the central housing portion 14. Moreover, the housing portions 16, 18 are removably secured to the central housing portion 14 so that the turbocharger mechanism can be removed as a unit with the central housing portion. <IMAGE>
