Club Line is a product engineered for small engine displacements. This includes powersports, personal watercraft, and automobiles. These turbochargers feature internally wastegated turbine housings 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. GBC20-300
39mm compressor inducer | 52mm compressor exducer
Outline interchangeable with GBC 17 / 22
150 –300 horsepower capability
Internal wastegate assembly with calibrated actuator
Billet compressor wheel with extended tip design for higher pressure ratio capability
GTX Gen II compressor aero with modern gasoline turbine wheel aero
Journal bearing rotating group
Engineered for small displacement engines including powersports, personal watercraft and automobiles
Read About Turbo System Optimization: A guide to setting up your turbocharger
The maximum power stated for each turbocharger has been calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel power. Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. Please consult with your local distributor before making a purchase.
