Why the Subaru FA20DIT Engine is So Popular

In the world of automotive engineering, Subaru has consistently pushed the envelope, creating engines that balance performance, reliability, and innovation. One such standout is the FA20DIT engine. This 2.0-liter, direct-injection turbocharged powerplant has become a favorite among enthusiasts and everyday drivers alike. But what makes the FA20DIT so popular? Let’s dive into the key reasons behind its acclaim.

1. Performance and Efficiency

At the heart of the FA20DIT's popularity is its impressive balance of performance and efficiency. The engine’s direct injection system allows for precise control of the air-fuel mixture, resulting in improved combustion efficiency. This not only boosts power output but also enhances fuel economy. The turbocharger further amplifies this by providing additional power on demand, without the need for a larger, less efficient engine.

2. Advanced Technology

The FA20DIT is a showcase of Subaru’s commitment to integrating advanced technology into their engines. Features such as variable valve timing (VVT) and a twin-scroll turbocharger contribute to the engine’s responsiveness and efficiency. The direct injection system also helps in achieving a more complete and efficient fuel burn, which translates to better performance and lower emissions.

3. Environmental Friendliness

In today’s automotive market, environmental considerations are more important than ever. The FA20DIT meets stringent emissions standards, thanks to its advanced combustion technology. The efficient fuel burn achieved by the direct injection system reduces harmful emissions, making the FA20DIT a more environmentally friendly option compared to older engines.

4. Enhanced Driving Experience

Drivers appreciate the FA20DIT for the enhanced driving experience it provides. The engine delivers smooth and responsive power, particularly at lower RPMs, which is ideal for both city driving and highway cruising. The turbocharged setup ensures that power is always available when needed, making the driving experience both exhilarating and dependable.

5. Reliability and Durability

Subaru’s reputation for building reliable and durable engines is well reflected in the FA20DIT. The use of high-quality materials and modern engineering practices ensures that this engine can withstand the rigors of daily driving as well as more spirited performance. Features such as the timing chain (as opposed to a timing belt) reduce maintenance needs and enhance longevity.

6. Innovative Design

The FA20DIT’s boxer engine layout contributes to its popularity. This design lowers the center of gravity of the vehicle, improving handling and stability. Subaru has optimized the boxer layout in the FA20DIT to provide a harmonious balance between performance and practicality.

7. Versatility

The FA20DIT is not just limited to one type of vehicle; its versatility is another key factor in its popularity. It powers a range of Subaru models, from the sporty WRX to the practical Forester. This versatility makes it a go-to engine for a variety of driving needs and preferences.

8. Community and Aftermarket Support

The FA20DIT has garnered a strong following in the automotive community. Enthusiasts appreciate the engine for its modifiability and the robust aftermarket support available. Whether it’s tuning for more power or adding performance parts, the FA20DIT provides a solid foundation for customization.


The Subaru FA20DIT engine stands out as a testament to Subaru’s engineering prowess. Its blend of performance, efficiency, and reliability has made it a popular choice among a diverse group of drivers. Whether you’re seeking a reliable daily driver, a performance-oriented machine, or an environmentally friendly vehicle, the FA20DIT delivers. Its advanced technology, innovative design, and strong community support ensure that this engine will remain a favorite for years to come. If you're considering a Subaru, the FA20DIT is a compelling reason to make that choice.
