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.
Compressor Aero:
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.
Internally Wastegated:
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.
Turbine Housing:
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.
