The first two numbers indicate the turbo frame size. The larger the number the larger the turbine wheel. The numbers following the dash indicate the peak potential flywheel horsepower rating. There are 4 Club Line turbochargers with different compressor inducer sizes and horsepower ranges: GBC14-200, GBC17-250, GBC20-300, and GBC22-350. GBC17, 20, 22 are outline interchangeable for use as stage upgrades.

Forged, fully-machined compressor wheels are offered in inducer sizes of 34mm, 36mm, 39mm, and 44mm. They can support from 200 up to 350 horsepower. The oil cooled center housing features the latest generation of journal bearing rotor group. Club Line turbochargers are fully assembled with an internally wastegated turbine housing. Garrett’s technicians calibrate the actuator for optimum performance, eliminating any need for adjustment. Club Line turbochargers are calibrated with a 0.5 bar actuator. Actuators with higher pressure settings (1.0, 1.5 bar) are available for individual purchase.
