GT4845 SPORTS TURBINE KIT FK8/FL5 is a direct bolt-on turbo upgrade for 2017-2024 Honda Civic Type R (FK8/FL5) K20C1 engines. It increases high RPM power and torque—up to ~384hp and 492N・m with proper tuning—without requiring fuel system upgrades, making it ideal for improved mid-to-high range performance.

Features and Details:

  • Turbocharger: Uses the specially designed GT4845 turbine with optimized wheel sizes, maintaining stock-like quick response while providing higher airflow.
  • Performance: Achieves roughly a 54ps increase over stock when paired with appropriate ECU remapping.
  • Installation: Direct bolt-on with the same layout as the stock turbo, including all necessary gaskets (exhaust, intake, water, and oil lines).
  • Fuel System: Designed to work with the stock fuel system (no injector upgrade needed).
  • Compatibility: Fits 2017-2021 Civic Type R (FK8) and 2023+ Civic Type R (FL5).
  • Recommendations: While it can run with stock settings, an ECU remap is recommended for maximum efficiency, and an upgraded intercooler kit is recommended for sustained high-power, high-temperature driving.
