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 67mm inducer size and 84mm exducer. GBC37-900 can support from 450-900 horsepower. The compressor wheel is a 64 trim and the Compressor housing A/R is 0.72 A/R. This turbocharger can support up to 87 lbs/min of airflow and up to 4.0 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 with 360 degree thrust bearing.

Turbine Housing

The GBC37-900 turbine housing inlet flanges are available in T3 open, T4 open, and T4 divided, and the outlet features a 90mm | 3.5 inch V-band connection.

Note: This is a plain bearing turbo & needs to have a minimum of a -4 oil feed line.
