A Complete Bolt-On Turbo System Built Specifically for the FA24
HKS engineered its GTIII-RS Bolt-On Turbo Kit as a comprehensive forced induction package for the FA24 engine used in the 2022 and newer Toyota GR86 and Subaru BRZ. Using the stock clutch and injectors, the kit raises peak output to approximately 269kW (366PS), a gain of about 92kW (125PS) over stock, and peak torque to about 391N-m, a gain of about 130N-m over stock, all while remaining a true bolt-on installation with no cutting, welding, or fabrication required.
Key Features
- HKS GTIII-RS ball-bearing turbocharger with 0.60 A/R turbine housing
- Internal wastegate set to approximately 65kPa boost pressure
- Raises peak output to approximately 269kW (366PS) using the stock clutch and injectors
- Cast exhaust manifold with integrated wastegate flange
- Front-mount intercooler with piping and turbo inlet/outlet piping
- Includes oil feed and return lines and coolant lines for the water-cooled turbo bearings
- True bolt-on design, no cutting, welding, or fabrication required

Forced Induction
Forced induction is the fastest way to add real power to an engine without adding displacement, and this collection covers the full range of turbocharger, supercharger, intercooler, and boost control hardware needed to build a reliable boosted platform. Whether you are running a factory turbo upgrade, swapping to a bigger frame turbocharger, adding a centrifugal or roots style supercharger, or dialing in a nitrous system for a quick shot of extra power, you will find the components here to build and support the setup correctly. Every part in this collection is organized by system type so you can move from a stock turbocharger to a properly supported forced induction build in one place. Intercoolers, wastegates, blow off valves, boost controllers, and water meth injection components are all included alongside the core turbo and supercharger hardware so the entire boost system can be sourced together. What This Category Covers This collection includes turbochargers, turbo kits, s...
