HKS GT2 Supercharger Pro Kit - 2022-2024 Toyota GR86 / Subaru BRZ

GT2 Supercharger Pro Kit for the 2022-2024 Toyota GR86 and Subaru BRZ

The HKS GT2 Supercharger Pro Kit for the 2022-2024 Toyota GR86 and Subaru BRZ brings HKS's twin-screw supercharger forced induction system to the FA24-powered second generation platform. The FA24 already offers a significant power increase over the FA20 with its additional displacement, and the GT2 supercharger takes that further. Adding boost from the bottom of the rev range and transforming the second-generation chassis into a car that uses its light weight and balance to full effect.

Specs & Highlights

• GT2 twin-screw supercharger system for FA24
• Immediate boost delivery from low RPM
• Complete kit for FA24 GR86 and BRZ application
• New GT2 kit developed specifically for the FA24 architecture
• Requires professional installation and ECU calibration
• Fitment: 2022-2024 Toyota GR86 / Subaru BRZ

Revised Head Unit for FA24, 7-9 psi, 280-300 whp

The FA24 GT2 kit uses a revised supercharger head unit with a larger rotor displacement than the FA20 version, matched to the FA24's greater displacement and higher stock airflow requirement. The drive ratio is calibrated for the FA24's 7,500 rpm redline. At standard pulley ratio, boost pressure is approximately 7–9 psi. Peak power outputs on the FA24 GT2 at standard configuration are documented by HKS at approximately 280–300 whp on a properly tuned car, roughly a 60–70 whp gain over a stock FA24's approximately 225 whp baseline.

Why the FA24 Kit Is Not an Adapted FA20 System

The FA24 GT2 kit is a new development: not an adapted FA20 kit. The FA24 engine architecture, displacement, and factory power level required HKS to develop a GT2 system specifically for it. The result is a supercharger kit matched to the FA24's airflow requirements and torque output, providing the same immediate boost delivery character that made the FA20 GT2 system so well-received.

Professional Installation and Full Dyno Tune Required

Professional installation and ECU calibration are required. The FA24 GT2 kit is a significant project and should be treated accordingly. Professional installation, proper tune on a chassis dyno, and a full review of supporting modifications (fuel system, oil cooling) before and during the process.

The FT Breakdown

The GT2 Supercharger for the 2022+ GR86 and BRZ is the most significant power upgrade available for the second-generation platform. HKS developed it specifically for the FA24 and the result reflects their depth of experience with the FT86 chassis going back to the FA20 generation. If you are building a second-generation GR86 or BRZ for real performance, this is the kit. The 60–70 whp gain from approximately 225 whp baseline to 280–300 whp on the GT2-equipped FA24 translates to a roughly 27–31% power increase on a platform that already had more power than the FA20 it replaced. For a 1,270 kg car, the resulting power-to-weight ratio approaches what you typically see from dedicated sports cars at twice the price.
