The FA20 engine, known for its lightweight and compact design, has become a popular choice among car enthusiasts looking to enhance performance. In this article, we will explore a real-world build of the FA20 engine that achieves 280 horsepower through forced induction. We will also discuss its daily driving performance, reliability, and overall experience.
Understanding the FA20 Engine
The FA20 is a flat-four engine developed by Subaru and Toyota, featuring a 2.0-liter displacement. It is known for its unique boxer design, which offers a lower center of gravity and improved handling characteristics. Here are some key specifications of the FA20 engine:
- Type: 2.0L Flat-Four (Boxer)
- Power Output: 200 hp (stock)
- Torque: 151 lb-ft (stock)
- Compression Ratio: 12.5:1
Forced Induction: The Path to 280 HP
To achieve the target of 280 horsepower, forced induction is a common modification. This can be done using either a supercharger or a turbocharger. In this build, a turbocharger was selected for its efficiency and power delivery characteristics.
Choosing the Right Turbocharger
When selecting a turbocharger, it is crucial to consider factors such as boost pressure, spool time, and overall compatibility with the FA20 engine. For this build, a Garrett GT2860RS turbocharger was chosen due to its balance of performance and reliability.
Supporting Modifications
To support the increased power output, several modifications were necessary:
- Upgraded fuel injectors (larger flow rate)
- High-performance intercooler
- Upgraded exhaust system (cat-back)
- ECU tuning for optimal performance
Daily Drive Performance
With the forced induction setup complete, it was time to evaluate the daily driving performance of the 280 hp FA20 build. Here are some key aspects of the driving experience:
Acceleration and Power Delivery
The turbocharged FA20 engine delivers power smoothly, with minimal lag. Acceleration is strong, especially in the mid-range, making it enjoyable for both city driving and highway merges.
Handling and Ride Quality
The boxer engine’s low center of gravity contributes to excellent handling characteristics. The vehicle remains stable during cornering, and the ride quality is comfortable enough for daily use.
Fuel Efficiency
Despite the performance upgrades, the FA20 build maintains respectable fuel efficiency. Daily driving yields an average of 25-28 miles per gallon, depending on driving habits.
Reliability and Maintenance
One of the concerns with forced induction builds is reliability. With proper tuning and quality components, this FA20 build has proven to be reliable for daily driving. Regular maintenance is essential, including:
- Frequent oil changes (synthetic oil recommended)
- Monitoring boost levels and engine temperatures
- Regular checks of the intercooler and piping for leaks
Conclusion
The 280 hp FA20 build with forced induction offers an exhilarating driving experience while remaining practical for daily use. With the right modifications and maintenance, this setup can deliver both performance and reliability, making it a popular choice for car enthusiasts.
For those considering a similar build, careful planning and quality parts are key to achieving the desired results without compromising reliability.
