Is GT86 tunable?
The GT86 is highly tunable. Its aftermarket support is broad and well established, allowing everything from simple performance tweaks to substantial forced-induction builds.
The Toyota 86 (and its siblings, the Subaru BRZ and Scion FR-S in earlier markets) uses a straightforward 2.0-liter FA20 engine and a lightweight, rear-drive chassis. That combination makes it a popular choice for tuners who want responsive handling and realistic, incremental power gains, with the potential for more dramatic upgrades under careful planning and professional tuning. Stock power is around 200 horsepower in many markets, with variations by year and region, and compression is relatively high, which is an important consideration for boosting. Outcomes depend on the parts chosen, the tune, and how far you push the engine’s limits.
Bolt-on upgrades that boost performance and feel
Before listing items, note that gains from bolt-on parts come from improving airflow, exhaust flow, and overall engine efficiency. When paired with a proper engine tune, these upgrades can deliver noticeable improvements without drastically changing the car’s reliability—at least at moderate power targets.
- Intake and air-filter improvements to improve charge air delivery
- Exhaust upgrades (cat-back or header-back) to reduce backpressure and free up flow
- Upgraded intercooler and piping for cars that run forced induction
- Throttle body and/or intake manifold tweaks (varying results by setup)
- Suspension and brake upgrades to maintain balance as power and weight transfer change
In practice, bolt-ons offer a cost-effective way to improve response and top-end power, especially when complemented by a calibrated engine-management tune.
Forced induction and engine management
Turbocharging or supercharging unleashes the GT86’s potential, but it requires careful planning, supporting hardware, and a reputable tune to maintain reliability and drivability.
- Turbocharger or supercharger kits that include the compressor, intercooler, hardware, and a tune
- Supporting upgrades such as a higher-capacity fuel pump, larger injectors, and proper fuel-pressure regulation
- Engine-management solutions or re-calibration via reputable tuning platforms (for example, popular tuners offer dedicated maps or flash options)
With the right combination of boost, fueling, cooling, and calibration, GT86s can produce significantly more power—often in the ballpark of a few hundred horsepower at the wheels, depending on boost targets and build quality. Longevity and reliability hinge on proper installation, maintenance, and ensuring the cooling and lubrication systems keep pace with the increased demands.
Chassis, transmission, and reliability considerations
Increased power shifts the balance of the car. Enthusiasts commonly upgrade the suspension, brakes, and drivetrain components to ensure handling and durability keep pace with the power gains. Aligning the gearing, LSD availability, and clamping force with the intended use is essential for predictable performance and longevity.
Warranty and legal considerations
Many aftermarket modifications can affect factory warranty coverage and may impact emissions compliance depending on your region. Track-oriented builds may be illegal for street use in some areas. Always check local regulations and consult with reputable tuners to understand the implications before proceeding.
Community, availability, and guidance
The GT86/BRZ/FR-S platform benefits from a large and active community, with tuners, clubs, and tech guides readily available. Because the platform overlaps with Subaru’s BRZ, there is cross-pollination of parts and knowledge, which broadens the range of options in markets around the world.
Summary
The GT86 is an exceptionally tunable platform, offering a spectrum of upgrades from affordable bolt-ons to comprehensive turbo or supercharged builds. Its light weight, rear-drive dynamics, and accessible engine make it a favorite among enthusiasts who want to tailor performance to their goals. Real-world results hinge on choosing appropriate parts, ensuring proper tuning, and aligning the build with your planned use—whether for daily driving, track days, or drifting—and on keeping maintenance up to date to protect longevity.
