HKS GTIII-RS Bolt On Turbo Kit - 2022 Toyota GR86 / 2022 Subaru BRZ

Ready to take your GR86 or BRZ beyond naturally aspirated performance? The HKS GTIII-RS Bolt-On Turbo Kit is a thoroughly engineered forced induction package designed specifically for the FA24-powered 2022–2026 Toyota GR86 and Subaru BRZ. Built around the proven HKS GTIII-RS turbocharger, this kit delivers a major increase in power while maintaining the quality, fitment, and reliability HKS is known for.

HKS reports gains of up to +128 hp and +104 lb-ft of torque over stock power figures, based on Japanese-spec BRZ testing. With a complete package that includes the turbocharger, exhaust manifold, catted downpipe, intercooler, piping, and intake components, this is one of the most complete and well-developed turbo solutions available for the second-generation 86/BRZ platform.

Key Features

• GTIII-RS Turbocharger: Mid-range HKS turbo designed to pair well with the larger-displacement FA24 engine.
• Major Power Gains: HKS reports up to 273kW max output, an increase of roughly +96kW / +128 hp over stock.
• Strong Torque Increase: Peak torque reaches 398N-m / 293 lb-ft, a gain of approximately +141N-m / +104 lb-ft over stock.
• FA24-Specific Design: Engineered for the 2022+ GR86 and BRZ platform.
• Improved Boost Control: Enlarged bypass port diameter in the exhaust housing helps improve boost pressure control and response.
• Complete Forced Induction Package: Includes turbocharger, manifold, catted downpipe, intercooler, piping, and Super Power Flow intake.

• Upgrade Path Available: Higher boost levels can be supported with HKS EVC7 and supporting clutch upgrades.

Why We Like It

The FA24 already gives the second-generation GR86/BRZ a stronger foundation than the original FA20, and this HKS kit takes that platform to another level. It is not just a turbo slapped onto the car; it is a full HKS-developed system with the hardware needed to support proper airflow, charge cooling, exhaust flow, and boost control. For owners who want a serious, name-brand forced induction setup, this is one of the big ones.
