HKS 2013-2020 Subaru BRZ / Toyota 86 | 2013-2016 FR-S - GT2 Supercharger System Pro Kit (w/o ECU Package) - 12001-KT004

Part No.: 12001-KT004 | Available at Just Bolt-On Performance Parts

For those looking to maximize power output while retaining full control over tuning, the HKS GT2 Supercharger System Pro Kit offers a bolt-on forced induction solution designed for the 2013–2020 Subaru BRZ, Toyota 86, and 2013–2016 FR-S. This kit excludes the ECU package, making it the perfect choice for custom tuning applications where professional calibration is desired.


Built for Tuners – Complete Supercharger System, No Preloaded ECU Map

Unlike the standard HKS GT2 Supercharger Kit with a pre-configured ECU package, this Pro Kit does not include engine management. Instead, it provides a blank slate for custom tuning, allowing professional tuners to fine-tune fueling, ignition timing, and boost control for maximum efficiency.

  • Requires standalone tuning – Ideal for those running aftermarket ECUs or custom tuning solutions.
  • Designed for 91 Octane Fuel – Pre-configured for safe, reliable performance on pump gas.
  • Supports Up to 320HP with E85 – With additional fueling upgrades, this system can deliver up to 90% more power over stock.

Massive Power Gains with Linear Boost Delivery

The GT2-7040L Supercharger delivers a linear, turbo-free powerband, providing instant throttle response without the lag typically associated with turbochargers.

  • HKS S/C 91 Octane Tune: 255HP (+80HP over stock)
  • HKS S/C E85 Tune (With Pulley & Fuel System Upgrades): 320HP (+150HP over stock)

Optional Pulley Upgrade Kit (sold separately) enables increased boost and power output.


Upgrade Path: Unlock Maximum Potential with E85

For those looking to maximize horsepower, the E85 fuel upgrade combined with a smaller pulley, upgraded injectors, and a high-flow fuel pump will transform the BRZ/FR-S/86 into a 320HP track monster.

Required Components for E85 Upgrade (sold separately):

  • Pulley Upgrade Kit (Part No.: 12002-KK001)
  • Deatsch Werks 700cc Fuel Injectors (Part No.: 16U-02-0700-4)
  • Deatsch Werks Fuel Pump (Part No.: 9-651-1010)

With these upgrades, the GT2 Supercharger System becomes a high-performance, ethanol-compatible powerhouse with increased torque and top-end horsepower.


Refined Supercharger Layout for Maximum Efficiency

HKS optimized the supercharger layout and pulley system for improved airflow, cooling, and seamless integration into the FA20 engine bay.

  • Compact, high-efficiency design reduces heat soak while delivering consistent boost pressure.
  • Requires minor modifications to bumper reinforcement, radiator support, and front chain cover.
  • Estimated installation time: 8 hours.

This bolt-on solution provides all the necessary components for a factory-like fitment, while allowing full flexibility for custom tuning applications.


Complete Kit – All Necessary Installation Parts Included

The GT2 Supercharger Pro Kit is a turnkey mechanical system, meaning it includes all necessary hardware, brackets, and piping for installation.

  • Designed specifically for BRZ, 86, and FR-S – No unnecessary modifications required.
  • Compatible with aftermarket engine management solutions – Perfect for custom-tuned setups.
  • Ideal for high-performance builds – Supports both 91-octane pump gas and E85 conversions.

Replacement & Repair Parts Available

For long-term reliability and maintenance, HKS offers replacement belts and supercharger overhaul kits.

  • V-Ribbed Belt 2160 (Part No.: 12002-KK003)
  • V-Ribbed Belt 2135 (Part No.: 12002-KK004)
  • GT2-7040L Supercharger Overhaul Kit (Part No.: 12002-KK102)

These parts ensure that your supercharged FA20 engine stays in peak condition for years to come.
