HKS GT Sports Turbine Kit (GT4845) – Honda Civic Type R FK8/FL5


Unlock the full potential of the K20C1 engine with the HKS GT Sports Turbine Kit (GT4845), engineered to deliver power at high RPM ranges that the stock turbo simply cannot achieve. Designed for enthusiasts seeking stronger top-end performance without sacrificing drivability, this bolt-on upgrade is a direct-fit solution built with precision by HKS.

The GT4845 turbocharger has been optimized in size and flow to eliminate the need for a fuel system upgrade under standard configurations, while still providing significant headroom for high-power builds when paired with supporting modifications. For maximum reliability during extended spirited driving or circuit use, the HKS Intercooler Kit (sold separately) is highly recommended.

While the turbo can be run without a piggyback system, ECU remapping is strongly advised to fully harness its performance gains and maintain optimal safety margins.

Key Features

  • High-RPM power gains beyond the limits of the stock turbo
  • No fuel system upgrade required under standard setups
  • Direct bolt-on fitment with stock-like layout for easy installation
  • Compatible with HKS intercooler kit for enhanced cooling and safety
  • Remapping recommended for maximum performance optimization
