G-Series G25-550 Turbocharger

The Garrett G-Series G25-550 is a high-performance turbocharger engineered for enthusiasts seeking significant power gains. This unit supports engine displacements ranging from 1.4L to 3.0L and is capable of producing up to 550 horsepower. The turbocharger features a forged, fully-machined compressor wheel with advanced aerodynamics that increase airflow and efficiency compared to previous generations. The turbine wheel is constructed from Mar-M alloy, rated for extreme exhaust gas temperatures up to 1050° C, and utilizes new turbine aero for higher flow and efficiency. Stainless steel turbine housings further enhance durability and temperature resistance. Key features include a fully machined speed sensor port for optional monitoring of turbocharger shaft speed (sensors sold separately and are not compatible with GT/GTX sensors). The one-piece center housing and backplate design enhance durability and safety. It also includes four large water jacket ports for improved cooling and customization of water line routing, along with a single stage oil passage with a supplied -4AN oil restrictor fitting. Performance results are dependent on vehicle modifications and tuning. The horsepower figures are based on the compressor map's choke flow, representing potential flywheel horsepower. It is recommended to install waterlines on opposite sides of the housing.
