A compressor housing for a turbocharger includes an outer housing structure, an inner housing structure, and a rear housing structure. The outer housing structure includes a first tubular portion and a first radial portion extending radially outward of the first tubular portion. The inner housing structure includes a second tubular portion and a second radial portion extending radially outward of the second tubular portion. The rear housing structure includes an inner radial portion and an outer radial portion extending radially outward of the inner radial portion. The outer housing structure, the inner housing structure, and the rear housing structure are formed separately from each other and are coupled to each other. A recirculation cavity is defined radially between the first tubular portion and the second tubular portion. A volute is cooperatively formed by the first radial portion and the outer radial portion.
