A turbocharger turbine, comprising: a turbine wheel; a housing having housing walls that define a turbine passageway, the passageway including a wheel chamber containing the turbine wheel, the wheel chamber extending downstream from an inducer to an exducer of the turbine wheel, and an outlet passage extending axially downstream from the exducer and defining a region of exducer flow, wherein the housing walls include an outlet passage wall surrounding the outlet passage; and a wastegate system having a controllable valve that controllably places the outlet passage in fluid communication with an inlet flow upstream of the inducer via a wastegate exhaust port; characterized in that the turbine further comprises: an injection body within the exducer flow within the outlet passage, the injection body having an outer wall further defining the region of exducer flow and the injection body having an injection body hollow interior in direct fluid communication with the exhaust flow from the wastegate exhaust port and a distal tip at a downstream end, the distal tip having an upstream end; wherein the injection body includes one or more injection ports upstream of the distal tip, the one or more injection ports placing the injection body hollow interior in fluid communication with the outlet passage within the exducer flow. a turbine wheel; a housing having housing walls that define a turbine passageway, the passageway including a wheel chamber containing the turbine wheel, the wheel chamber extending downstream from an inducer to an exducer of the turbine wheel, and an outlet passage extending axially downstream from the exducer and defining a region of exducer flow, wherein the housing walls include an outlet passage wall surrounding the outlet passage; and a wastegate system having a controllable valve that controllably places the outlet passage in fluid communication with an inlet flow upstream of the inducer via a wastegate exhaust port; characterized in that the turbine further comprises: an injection body within the exducer flow within the outlet passage, the injection body having an outer wall further defining the region of exducer flow and the injection body having an injection body hollow interior in direct fluid communication with the exhaust flow from the wastegate exhaust port and a distal tip at a downstream end, the distal tip having an upstream end; wherein the injection body includes one or more injection ports upstream of the distal tip, the one or more injection ports placing the injection body hollow interior in fluid communication with the outlet passage within the exducer flow. an injection body within the exducer flow within the outlet passage, the injection body having an outer wall further defining the region of exducer flow and the injection body having an injection body hollow interior in direct fluid communication with the exhaust flow from the wastegate exhaust port and a distal tip at a downstream end, the distal tip having an upstream end; wherein the injection body includes one or more injection ports upstream of the distal tip, the one or more injection ports placing the injection body hollow interior in fluid communication with the outlet passage within the exducer flow.
