Turbine Housing Options

Each turbine housing is listed by A/R (area-to-radius ratio), inlet flange, outlet and wastegate type. "Internal" housings have a built-in wastegate; "External" housings are free-float designs that require an external wastegate.

Important Information

Garrett calculates its horsepower ratings from the compressor map choke flow, which represents the potential flywheel horsepower of the turbo. Actual results depend on the engine, supporting modifications and calibration.
