Abstract: A turbocharger is provided including a turbine housing having a gas inlet passage. A turbine wheel having a plurality of blades is arranged within the turbine housing. A nozzle ring is disposed around the turbine wheel and includes a plurality of vanes with flow channels being defined between the vanes that are in fluid communication the gas inlet passage and with the turbine wheel. A shroud is arranged in surrounding relation to at least a portion of the turbine wheel and in spaced relation from the turbine housing. The shroud is integrally formed with the nozzle ring such that the plurality of vanes extend away from the shroud.
