The FA20 engine, known for its balance of performance and efficiency, has become a popular choice among automotive enthusiasts. Upgrading the internals of the FA20 can significantly enhance performance, but it is essential to weigh the costs against the benefits. This article explores the key aspects of upgrading the FA20 internals for high-performance builds under $2,000.
Understanding the FA20 Engine
The FA20 is a flat-four engine produced by Subaru, primarily used in models like the Subaru BRZ and Toyota 86. Its unique design offers a low center of gravity, contributing to better handling. However, as with any engine, there are limitations to its performance capabilities.
Benefits of Upgrading Internals
Upgrading the internals of the FA20 can lead to several benefits, including:
- Increased Horsepower: Enhanced components can boost overall engine power.
- Improved Torque: Upgrades can lead to better torque delivery, especially in low-end RPMs.
- Better Reliability: High-performance parts can withstand greater stress, improving engine longevity.
- Enhanced Driving Experience: A more responsive engine can elevate the overall driving experience.
Key Upgrades for Performance
When considering upgrades, it is crucial to choose parts that offer the best performance-to-cost ratio. Here are some recommended upgrades:
- Pistons: High-compression pistons can significantly increase power output.
- Connecting Rods: Upgrading to forged rods enhances strength and reliability.
- Camshafts: Performance camshafts can improve airflow and increase horsepower.
- Valves and Springs: Upgraded valves and springs allow for higher RPMs and better performance.
Cost Breakdown of Upgrades
To stay within the $2,000 budget, careful planning and selection of parts are necessary. Below is a rough cost breakdown of potential upgrades:
- Pistons: $500 – $800
- Connecting Rods: $400 – $600
- Camshafts: $300 – $500
- Valves and Springs: $250 – $400
- Labor Costs: $300 – $500 (if not DIY)
DIY vs. Professional Installation
Deciding between DIY installation and hiring a professional can impact your overall costs. Here are some considerations:
- DIY: Saves labor costs but requires mechanical knowledge and tools.
- Professional Installation: Ensures proper installation but adds to the overall expense.
Potential Risks and Considerations
While upgrading the internals can yield significant benefits, there are risks to consider:
- Reliability: Higher performance parts may lead to decreased reliability if not installed correctly.
- Engine Management: Upgrades may require a re-tune of the engine management system for optimal performance.
- Warranty Issues: Upgrading can void vehicle warranties, so check before proceeding.
Conclusion
Upgrading the FA20 internals can lead to impressive performance gains for under $2,000. By carefully selecting parts and considering installation options, enthusiasts can achieve a high-performance build that enhances their driving experience. Always weigh the costs against potential benefits and risks to make informed decisions about your upgrades.
