The BRZ FA20 is a fantastic platform for performance enthusiasts looking to enhance their driving experience. With a few affordable modifications, achieving over 250 horsepower is not only possible but also a thrilling journey. In this article, we will explore the top performance upgrades that can help you reach this goal without breaking the bank.
Understanding the FA20 Engine
The FA20 engine, found in the Subaru BRZ and Toyota 86, is a 2.0-liter flat-four engine that offers a unique combination of lightweight design and low center of gravity. While it delivers a respectable amount of power, many enthusiasts seek to unlock its full potential through various upgrades.
Top Performance Upgrades for the BRZ FA20
- Cold Air Intake: An upgraded cold air intake can significantly improve airflow to the engine, resulting in better throttle response and increased horsepower.
- Cat-Back Exhaust System: A performance exhaust system not only enhances the sound of your BRZ but also improves exhaust flow, contributing to a power increase.
- Tune: A custom ECU tune can optimize your engine’s performance, allowing it to take full advantage of other modifications.
- Headers: Upgrading to performance headers can reduce back pressure and improve exhaust flow, leading to noticeable gains in horsepower.
- Turbocharger Kit: For those seeking significant power increases, a turbocharger kit can elevate horsepower levels dramatically, often exceeding 250 hp.
- Upgraded Fuel Injectors: More powerful injectors ensure that your engine receives the proper fuel supply, especially when running higher boost levels.
- Intercooler Upgrade: If you add forced induction, an upgraded intercooler will help maintain optimal air temperatures, improving performance and reliability.
Detailed Breakdown of Each Upgrade
Cold Air Intake
Installing a cold air intake is one of the simplest and most effective upgrades for the BRZ FA20. This modification allows for cooler, denser air to enter the engine, improving combustion efficiency and power output. Many aftermarket options are available, providing a noticeable increase in performance and engine sound.
Cat-Back Exhaust System
A cat-back exhaust system replaces the factory exhaust from the catalytic converter back, enhancing exhaust flow and reducing restrictions. This upgrade not only improves horsepower but also gives your BRZ a more aggressive exhaust note, making your driving experience more enjoyable.
Tune
After installing performance upgrades, a custom tune is essential to maximize gains. A professional tuner can adjust fuel maps, ignition timing, and other parameters to ensure your engine runs efficiently and safely with the new modifications. This step is crucial for achieving the desired horsepower and reliability.
Headers
Upgrading to performance headers can reduce exhaust back pressure, allowing for a smoother and more efficient exhaust flow. This modification typically results in noticeable power gains, especially when combined with other upgrades like a cat-back exhaust and a tune.
Turbocharger Kit
For those looking for serious power, a turbocharger kit can significantly increase horsepower, often pushing the BRZ FA20 well beyond 250 hp. This upgrade involves more complex installation and tuning but offers the most dramatic performance improvement. It’s essential to consider supporting modifications, such as an upgraded fuel system and intercooler, to ensure reliability.
Upgraded Fuel Injectors
When increasing horsepower, ensuring your engine receives enough fuel is critical. Upgraded fuel injectors can provide the necessary flow to support higher power levels, especially when combined with a turbocharger or other significant modifications.
Intercooler Upgrade
When adding forced induction, an upgraded intercooler is vital for maintaining optimal air temperatures. Cooler air entering the engine leads to better performance and prevents knock, ensuring your modifications work effectively and safely.
Conclusion
Achieving over 250 horsepower in your BRZ FA20 is an exciting challenge that can be accomplished with the right upgrades. From simple modifications like a cold air intake to more complex installations like a turbocharger kit, each upgrade contributes to a more thrilling driving experience. By carefully selecting and installing these affordable mods, you can unlock the full potential of your BRZ and enjoy the road like never before.
