The FA20 engine, known for its balance of performance and efficiency, is a popular choice among car enthusiasts. With a few strategic modifications, you can significantly enhance its power without spending a fortune. This article explores various performance mods for the FA20 engine, all priced under $500, allowing you to maximize your vehicle’s potential while keeping your budget intact.
Understanding the FA20 Engine
The FA20 is a 2.0-liter flat-four engine developed by Subaru. It features a unique design that offers a lower center of gravity and improved handling. While the engine provides a solid foundation for performance, there are several modifications you can implement to unlock more power.
Popular Performance Mods Under $500
When looking to enhance the FA20’s performance, consider the following modifications, all of which can be completed for under $500:
- Cold Air Intake: Replacing the stock air intake system with a cold air intake can improve airflow to the engine, leading to better combustion and increased horsepower.
- Cat-Back Exhaust System: Upgrading to a cat-back exhaust system can reduce back pressure, allowing the engine to breathe more freely and increasing power output.
- ECU Tune: A performance ECU tune can optimize fuel maps and ignition timing, resulting in noticeable gains in horsepower and torque.
- Upgraded Intercooler: For those looking to push their FA20 further, an upgraded intercooler can help maintain lower intake temperatures, improving performance.
- Lightweight Flywheel: Installing a lightweight flywheel can reduce rotational mass, allowing the engine to rev more freely and improving throttle response.
Detailed Breakdown of Each Modification
Cold Air Intake
A cold air intake system replaces the factory air intake, allowing cooler air to enter the engine. Cooler air is denser, leading to better combustion and more power. Popular options include brands like AEM and K&N, which offer systems that are easy to install and provide noticeable performance improvements.
Cat-Back Exhaust System
A cat-back exhaust system replaces the exhaust components from the catalytic converter back, improving exhaust flow and reducing back pressure. This mod not only enhances performance but also gives your vehicle a more aggressive sound. Look for systems from Borla or Invidia that fit within the budget.
ECU Tune
An ECU tune can significantly alter the performance characteristics of your FA20 engine. By adjusting parameters such as fuel delivery and ignition timing, you can unlock hidden power. Many tuners offer packages that include both the software and a handheld tuner for easy installation.
Upgraded Intercooler
For turbocharged FA20 engines, an upgraded intercooler can be a game-changer. It cools the intake air before it enters the engine, allowing for denser air and more power. Brands like Mishimoto offer affordable options that can be easily installed without extensive modifications.
Lightweight Flywheel
A lightweight flywheel reduces the mass that the engine has to turn, resulting in quicker revs and improved throttle response. This modification can enhance your driving experience significantly. Look for options from Exedy or ACT that fit the FA20 engine.
Installation Tips and Considerations
While many of these modifications can be installed at home, some may require professional assistance. Here are a few tips to consider:
- Research: Before purchasing any parts, research compatibility and installation processes to avoid issues.
- Tools: Ensure you have the necessary tools for installation, including wrenches, sockets, and possibly a torque wrench.
- Follow Instructions: Always follow the manufacturer’s instructions carefully to avoid damaging components.
- Consider Professional Help: If you’re unsure about any installation, consider hiring a professional mechanic.
Conclusion
The FA20 engine offers a great platform for performance modifications without requiring a massive investment. By implementing these mods under $500, you can significantly enhance your vehicle’s power and driving experience. Remember to always consider your goals and budget when choosing modifications, and enjoy the journey of tuning your FA20 engine.
