Garrett Boost Club Line GBC14-200 34 mm turbo – 896051-5004S
Compact performance turbo for small engines
Garrett Boost Club Line GBC14-200 is developed for small engine displacements where fast response, compact size, and stable performance are important. This turbo is suitable for small cars, powersports, jet skis, and other applications with engines from approx. 0.4 to 1.0 litres. The internal wastegate makes installation simpler, and the oil-cooled centre housing with journal bearings provides a reliable solution for performance use.
GBC stands for Garrett Boost Club Line, and the GBC14-200 model is built around a compact frame with a 34 mm compressor inducer. The turbo is designed to support approx. 140–200 hp, depending on engine setup, tuning, and other modifications. The maximum power rating is based on the total flow capacity of the compressor and should therefore be seen as the turbo’s potential – not as a guarantee of a specific result on every engine.
The compressor wheel is a forged, fully machined wheel with modern aerodynamic design, delivering efficient airflow and strong performance for its size. The turbo can provide up to approx. 22 lb/min airflow and up to 2.8 pressure ratio, making it suitable for smaller high-performance engine projects where a compact and efficient turbo system is required.
The internal wastegate is pre-assembled by Garrett, and the actuator is factory calibrated for optimum function. The standard setup comes with a 0.5 bar actuator, but actuators with higher pressure settings can be purchased separately. This makes the model interesting for both standardised and more custom-built setups.
The centre housing is oil-cooled and built with Garrett’s latest generation journal bearing rotating group, providing a robust and classic bearing solution. The turbine housing also features an inlet that can be machined for V-band with 57 mm outside diameter for use with 1.75” tubing, offering good possibilities for custom installations.
