Understanding the FA20 Engine
The FA20 is a 2.0-liter flat-four engine that powers several Subaru models, including the BRZ and the Toyota 86. With its lightweight design and low center of gravity, the FA20 is an excellent platform for performance enhancements. To reach the target of 320 horsepower, various components must be upgraded or replaced.
Key Upgrades to Achieve 320 HP
- Turbocharger Upgrade
- Fuel System Enhancements
- ECU Tuning
- Exhaust System Upgrade
- Intake System Improvements
Turbocharger Upgrade
A turbocharger is essential for increasing horsepower significantly. Upgrading to a larger turbo can provide the necessary boost to reach 320 HP. The cost for a quality turbocharger typically ranges from $1,500 to $3,000, depending on the brand and specifications.
Fuel System Enhancements
To support increased horsepower, the fuel system must be capable of delivering more fuel. Upgrades may include larger fuel injectors and a high-flow fuel pump. The total cost for these enhancements can be around $600 to $1,200.
ECU Tuning
ECU tuning is crucial for optimizing engine performance after modifications. A professional tune can ensure that the engine runs efficiently and safely at higher power levels. The cost of ECU tuning typically ranges from $500 to $1,000.
Exhaust System Upgrade
Upgrading the exhaust system helps to reduce back pressure and improve engine efficiency. A performance exhaust system can cost between $800 and $2,000, depending on the materials and design.
Intake System Improvements
An upgraded intake system allows for better airflow into the engine, which is vital for performance. Cold air intakes and high-performance filters can range from $300 to $800.
Estimated Total Costs
When calculating the total costs for achieving 320 HP with FA20 upgrades, consider the following breakdown:
- Turbocharger: $1,500 – $3,000
