A process for calibrating a variable-nozzle assembly () prior to its installation in a turbocharger. The variable-nozzle assembly facilitating such process is installed in a calibration fixture () having internal flowpath contours configured to replicate corresponding internal flowpath contours of a turbocharger into which the variable-nozzle assembly () is to be installed. The calibration fixture () defines a generally annular chamber () in fluid communication with a flow path defined in the variable-nozzle assembly (), and a fluid supply passage () extending into the annular chamber. A fluid is supplied through the fluid supply passage (), and the fluid then flows through the flow path of the variable-nozzle assembly (). While the fluid is flowing through the variable-nozzle assembly (), the vanes () are pivoted to set a predetermined flow rate. A stop member () is then fixed to the variable-nozzle assembly () so that the vanes () cannot be pivoted past the position corresponding to the predetermined flow rate.
