The GBC-series is engineered for small displacement engines including powersports, personal watercraft and automobiles

Garrett now launches a new line of turbochargers that are close to the BorgWarner AirWerks S1BG turbochargers - the GBC series. Garrett Boost Club Line turbochargers are engineered for small engine displacements including powersports, personal watercraft, and automobiles. These turbochargers feature internally wastegated turbine housings and journal bearing rotating groups. Forged, fully-machined compressor wheels can support from 200 up to 350 horsepower for engine displacements ranging from 0.4L up to 2.5L.

Club Line is a product engineered for small engine displacements. This includes powersports, personal watercraft, and automobiles. These turbochargers feature internally wastegated turbine housings, 0,5 bar actuator (optional available 480009-0006 = 1.0 bar, 480009-0010 = 1.5 bar) and journal bearing rotating groups. GBC stands for GARRETT BOOST | CLUB LINE.

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.
