HKS GTSC 100 mm Pulley Upgrade Kit V3 - Toyota GT86 / Subaru BRZ (2012+)
The HKS GTSC 100 mm Pulley Upgrade Kit V3 is designed for the Toyota GT86 and Subaru BRZ (2012+) equipped with the HKS GTSC V3 Supercharger Kit. By replacing the standard pulley with a smaller 100 mm version, the supercharger spins at a higher speed, increasing boost pressure, improving throttle response, and delivering stronger performance throughout the mid- and high-RPM range.
This upgrade is specifically intended for engines with performance ECU tuning and is best suited for vehicles running on E85 or race fuel, where the increased boost pressure can be fully utilized. The result is stronger acceleration and a more responsive driving experience under demanding conditions.
The pulley upgrade is a direct replacement for the original pulley used in the HKS GTSC V3 Supercharger Kit, ensuring straightforward installation and OEM-style fitment.
