The FA20 engine, known for its balance of performance and efficiency, has gained popularity among car enthusiasts. However, as with any performance upgrades, potential buyers should consider the long-term reliability of these modifications.
Understanding the FA20 Engine
The FA20 is a flat-four engine developed by Subaru, used in various models like the Subaru BRZ and Toyota 86. Its design offers a low center of gravity, contributing to better handling and overall performance.
Common Performance Upgrades
- Cold Air Intakes
- Exhaust Systems
- ECU Tuning
- Turbocharger Kits
- Suspension Upgrades
Cold Air Intakes
Cold air intakes are designed to improve airflow to the engine, potentially increasing horsepower. However, long-term exposure to dirt and debris can lead to engine wear if not properly maintained.
Exhaust Systems
Upgrading the exhaust system can enhance performance by reducing back pressure. While many aftermarket systems are durable, poor installation can lead to leaks and other issues over time.
ECU Tuning
ECU tuning adjusts the engine’s parameters for improved performance. While it can yield significant gains, improper tuning can lead to engine knock and other reliability issues.
Turbocharger Kits
Adding a turbocharger can dramatically increase power. However, it places additional stress on engine components, which may reduce long-term reliability if not properly managed.
Suspension Upgrades
Upgrading the suspension improves handling and stability. While these upgrades are generally reliable, they can affect ride comfort and may require more frequent maintenance.
Factors Influencing Long-Term Reliability
- Quality of Parts
- Installation Process
- Regular Maintenance
- Driving Habits
- Environmental Conditions
Quality of Parts
Using high-quality aftermarket parts can significantly impact the reliability of performance upgrades. Cheaper parts may save money initially but can lead to failures and costly repairs down the line.
Installation Process
Proper installation is crucial for the longevity of performance upgrades. Hiring experienced professionals can help avoid common pitfalls that lead to reliability issues.
Regular Maintenance
Regular maintenance checks are essential for any modified vehicle. Keeping an eye on fluid levels, tire conditions, and engine performance can help catch potential issues early.
Driving Habits
Driving style can greatly affect the wear and tear of performance upgrades. Aggressive driving can lead to faster degradation of engine components compared to more conservative driving habits.
Environmental Conditions
Environmental factors such as temperature, humidity, and road conditions can influence the longevity of performance upgrades. Vehicles driven in harsher conditions may require more frequent inspections and maintenance.
Potential Risks of Performance Upgrades
- Engine Damage
- Increased Wear on Components
- Warranty Voidance
- Insurance Implications
Engine Damage
Performance upgrades can increase the risk of engine damage if not done correctly. Overboosting a turbo or improper tuning can lead to catastrophic engine failure.
Increased Wear on Components
Higher performance levels can lead to increased wear on engine components. It’s essential to monitor these parts closely to prevent premature failure.
Warranty Voidance
Many manufacturers void warranties on vehicles with aftermarket modifications. Buyers should consider this risk when planning upgrades.
Insurance Implications
Performance upgrades may also impact insurance premiums. It’s important to inform your insurance provider about any modifications to ensure proper coverage.
Conclusion
While the FA20 engine offers great potential for performance upgrades, buyers must carefully consider the long-term reliability of these modifications. By understanding the risks and maintaining their vehicles properly, enthusiasts can enjoy enhanced performance without sacrificing reliability.
