A twin-vaned nozzle ring for a turbine nozzle of a turbocharger nozzle ring is made by assembling the nozzle ring from three separately formed parts. A center part includes a first ring of circumferentially spaced first vanes and a second ring of circumferentially spaced second vanes, the first and second rings being axially spaced and integrally joined to each other. The first vanes are circumferentially offset from the second vanes, and exits from the first vane passages are radially aligned with and circumferentially interleaved with exits from the second vane passages. First and second side walls are provided as separate parts. Finally, the first side wall is joined to a distal or outer face of the first ring, and the second side wall is joined to a distal face of the second ring to complete the assembly.
