Turbo PN: 896053-5003S
The best solution for small engine displacements
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.
Forged, fully-machined compressor wheels with advanced aero is offered in 39mm inducer size and 52mm exducer. GBC20-300 can support from 170-300 horsepower. The compressor wheel is a 57 trim and the Compressor housing A/R is 0.59 A/R. This turbocharger can support up to 29 lbs/min of airflow and up to 3.7 pressure ratio. Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The target power represented has been calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel power.
Journal Bearing Rotating Group
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.
The GBC20-300 turbine housing inlet flange is standard T25 spec, and the outlet features a 5 bolt pattern. The 5 bolt outlet pattern is the same flange as the GT25 / GT28 turbos.
Compressor Housing Specs
The compressor housing outlet and inlet specs are the same at GT22 turbochargers.
