The Subaru BRZ, powered by the FA20 engine, has gained popularity among car enthusiasts for its lightweight design and engaging driving experience. For those looking to enhance performance, achieving reliable 240+ horsepower is a common goal. This article will explore tuning options, essential parts, and cost tips to help you reach that target.
Tuning Options for the FA20 Engine
Tuning is a critical aspect of increasing horsepower. The FA20 engine can benefit from various tuning methods to unlock its potential. Here are some popular options:
- ECU Remapping: Reprogramming the engine control unit (ECU) can optimize fuel maps and ignition timing.
- Aftermarket Tunes: Several companies offer pre-configured tunes specifically for the FA20 engine.
- Dyno Tuning: Custom tuning on a dynamometer ensures your vehicle runs efficiently at its peak performance.
Choosing the Right Tuner
Selecting a reputable tuner is crucial. Look for tuners with experience in Subaru vehicles and a proven track record. Online reviews and community recommendations can guide you in making the right choice.
Essential Parts for Performance Enhancement
To achieve reliable horsepower gains, certain aftermarket parts are essential. Here’s a list of components that can help you reach and maintain that 240+ hp mark:
- Cold Air Intake: Improves airflow to the engine, enhancing combustion efficiency.
- Cat-Back Exhaust System: Reduces back pressure and allows for better exhaust flow.
- Turbocharger or Supercharger Kit: Forced induction significantly increases horsepower.
- Intercooler Upgrade: Keeps intake temperatures low, improving performance and reliability.
- High-Performance Fuel Injectors: Ensures adequate fuel delivery for increased power levels.
Cold Air Intake
A cold air intake can provide noticeable power gains. It allows the engine to breathe better, resulting in improved throttle response and increased horsepower. Popular brands include AEM and Injen.
Cat-Back Exhaust System
A cat-back exhaust system replaces the factory exhaust from the catalytic converter back. This modification reduces restrictions and enhances exhaust flow, contributing to power gains and a more aggressive sound.
Forced Induction
Adding a turbocharger or supercharger is one of the most effective ways to increase horsepower. Both options have their pros and cons, so consider your driving style and goals when choosing.
Intercooler Upgrade
If you choose forced induction, upgrading the intercooler is crucial. A larger intercooler keeps air temperatures lower, which helps maintain performance and prevents engine knock.
High-Performance Fuel Injectors
As you increase horsepower, the stock fuel injectors may struggle to keep up. Upgrading to high-performance injectors ensures your engine receives the necessary fuel for optimal performance.
Cost Considerations
Budgeting for performance upgrades is essential. Here’s a breakdown of potential costs associated with tuning and parts:
- ECU Tune: $400 – $1,200 depending on the tuner and method.
- Cold Air Intake: $200 – $400.
- Cat-Back Exhaust System: $500 – $1,500.
- Turbocharger or Supercharger Kit: $2,500 – $7,000.
- Intercooler Upgrade: $300 – $1,000.
- High-Performance Fuel Injectors: $300 – $600.
Keep in mind that prices can vary based on brands, installation costs, and local market conditions. Always plan for additional expenses such as labor and potential unforeseen modifications.
Conclusion
Achieving reliable 240+ horsepower on your BRZ FA20 is an attainable goal with the right tuning, parts, and budget considerations. By investing in quality components and working with experienced tuners, you can enjoy an exhilarating driving experience while ensuring your vehicle remains reliable. Happy tuning!
