The FA20 engine, known for its lightweight and efficient design, has gained popularity among car enthusiasts looking to enhance performance. With the right upgrades, it’s possible to achieve significant power gains. In this article, we will explore the top 10 power gains achievable with Stage 2 upgrades, focusing on improvements that can boost horsepower by 50 to 100 HP.
1. High-Performance Turbocharger
Upgrading to a high-performance turbocharger is one of the most effective ways to increase horsepower. A larger turbo can improve airflow and boost levels, resulting in substantial power gains.
Benefits
- Increased airflow and efficiency
- Higher boost pressure
- Enhanced throttle response
2. Performance Intercooler
A performance intercooler helps to lower the temperature of the intake air, which can lead to denser air and more power. This upgrade is essential when increasing boost levels.
Benefits
- Improved cooling efficiency
- Reduced risk of knock
- Enhanced performance under load
3. Upgraded Fuel Injectors
To support increased horsepower, upgrading to larger fuel injectors ensures that the engine receives enough fuel to match the increased air from the turbocharger.
Benefits
- Improved fuel delivery
- Better throttle response
- Supports higher horsepower levels
4. Performance Exhaust System
A performance exhaust system reduces back pressure and improves exhaust flow, allowing the engine to breathe better and produce more power.
Benefits
- Increased horsepower and torque
- Enhanced engine sound
- Improved overall efficiency
5. ECU Tune
A proper ECU tune is crucial after making hardware upgrades. It adjusts fuel maps, ignition timing, and boost levels to maximize performance and reliability.
Benefits
- Optimized engine performance
- Increased horsepower and torque
- Improved fuel efficiency
6. Lightweight Flywheel
Installing a lightweight flywheel reduces rotational mass, allowing the engine to rev faster and improving acceleration. This upgrade enhances the overall driving experience.
Benefits
- Faster engine response
- Improved acceleration
- Reduced engine load
7. Cold Air Intake
A cold air intake system increases airflow to the engine while reducing intake temperatures. This can lead to noticeable power gains, especially when paired with other upgrades.
Benefits
- Improved airflow
- Enhanced engine sound
- Better fuel efficiency
8. Upgraded Turbo Wastegate
An upgraded wastegate allows for better control of boost levels, preventing boost creep and ensuring consistent performance under high loads.
Benefits
- Improved boost control
- Reduced turbo lag
- Enhanced reliability
9. High-Performance Camshafts
Upgrading to high-performance camshafts can improve valve timing and lift, leading to better airflow and increased power throughout the RPM range.
Benefits
- Increased horsepower
- Improved torque curve
- Enhanced engine responsiveness
10. Upgraded Oil Cooler
Maintaining optimal oil temperatures is crucial for engine performance. An upgraded oil cooler ensures that the engine runs efficiently, especially under high-performance conditions.
Benefits
- Improved engine longevity
- Consistent performance
- Reduced risk of overheating
By implementing these Stage 2 upgrades, FA20 engine owners can achieve substantial power gains, transforming their vehicles into high-performance machines. Each upgrade plays a vital role in enhancing overall performance, making them essential for those looking to maximize their engine’s potential.
