Engine Performance Modifications for GT86
Popular tuning modifications done to GT86 engine to improve performance
As a well-balanced car, GT86 is a popular platform to build a RWD project car. Listed below are some popular modifications that enthusiasts commonly perform on the Toyota GT86 engine to enhance its performance:
Cold Air Intake (CAI): A CAI replaces the stock air intake system with a more efficient one, allowing cooler and denser air to enter the engine, resulting in improved horsepower and throttle response.
Exhaust System Upgrade: Upgrading the exhaust system with headers, high-flow catalytic converters, and a performance muffler can improve exhaust flow, increase engine efficiency, and enhance the engine's sound.
ECU Tuning: Engine Control Unit (ECU) tuning involves reprogramming the engine's computer to optimize fuel and ignition timing, leading to increased power, torque, and overall performance.
Forced Induction: Installing a turbocharger or supercharger kit adds forced induction, significantly boosting the engine's power output. This modification requires supporting upgrades such as intercoolers, fuel system upgrades, and engine strengthening depending on the desired power levels.
Intake Manifold Upgrade: Upgrading the intake manifold can improve airflow and fuel distribution, resulting in enhanced performance across the RPM range.
Camshaft Upgrades: High-performance camshafts can increase valve lift and duration, improving engine breathing and power delivery, especially at higher RPMs.
Fuel System Enhancements: Upgrading fuel injectors, fuel pumps, and adding a fuel pressure regulator can support higher horsepower levels and improve fuel delivery for modified engines.
Ignition System Upgrades: Upgrading to high-performance ignition coils, spark plugs, and ignition wires can improve ignition efficiency, leading to smoother engine operation and potentially increased power.
Cooling System Modifications: Upgrading the radiator, adding an oil cooler, and improving coolant circulation can help maintain optimal engine temperatures, especially under high-performance driving conditions.
Throttle Body Upgrade: Installing a larger throttle body can increase airflow into the engine, enhancing throttle response and overall engine performance.
These modifications should be approached with caution and may require additional supporting upgrades to ensure reliability, such as upgraded engine internals, strengthened drivetrain components, and a properly tuned engine management system. It's also important to consider local laws and regulations regarding vehicle modifications.
