BNR-770 Turbo Upgrade for 2022+ Subaru WRX VB (FA24)
The BNR-770 Turbo Upgrade is the largest and most powerful bolt-on turbocharger option available for the 2022–current Subaru WRX VB equipped with the FA24 engine. Designed for enthusiasts searching for serious Subaru WRX VB turbo upgrades, big turbo kits, or high-horsepower FA24 solutions, the BNR-770 delivers exceptional airflow, response, and reliability while retaining a true bolt-in fitment.
At the heart of the BNR-770 is a ceramic dual ball bearing CHRA paired with advanced G-series aerodynamic compressor and turbine wheels. This combination allows the turbo to flow an impressive 77 lb/min of airflow, supporting 600+ horsepower in a bolt-on configuration with proper supporting modifications and tuning. All units are VSR balanced up to 150,000 RPM to ensure smooth operation, longevity, and consistent performance under high boost.
The turbine side features a twin-scroll .80 A/R turbine housing machined for a G30 turbine wheel, delivering strong top-end power without sacrificing drivability. On the compressor side, a .70 A/R compressor housing with an integrated speed sensor bung provides excellent efficiency and tuning flexibility. The BNR-770 spools well on vehicles with a stock fuel system and truly shines on built FA24 engines looking to push the limits of the Subaru WRX VB platform.
As an added value, every BNR-770 Turbo Upgrade includes BNR’s upgraded cast aluminum turbo inlet duct at no additional cost—a $250 value. This upgraded inlet improves airflow, durability, and overall turbo efficiency, making this one of the most complete WRX VB turbo kits available.
