The Mitsubishi Eclipse equipped with the 4G63 engine is a beloved platform for enthusiasts seeking performance. While the engine itself is capable, enhancing its performance through affordable supporting modifications can yield impressive results. This article explores some cost-effective mods that can help you maximize the potential of your 4G63 engine.
Understanding the 4G63 Engine
The 4G63 engine is a 2.0L inline-four engine that has gained a reputation for its durability and tunability. It was used in various Mitsubishi models, including the Eclipse, Talon, and Galant. The engine’s design allows for significant performance upgrades, making it a popular choice among tuners.
- 2.0L inline-four configuration
- Turbocharged variant available
- Strong aftermarket support
Key Supporting Mods
To get the most out of your 4G63 engine, consider the following affordable supporting modifications:
- Cold Air Intake: A cold air intake system increases airflow to the engine, improving combustion efficiency and power output.
- Upgraded Intercooler: A larger intercooler helps reduce intake temperatures, allowing for denser air and better performance.
- High-Performance Exhaust System: Upgrading to a free-flowing exhaust system reduces back pressure and enhances exhaust flow, which can lead to increased horsepower.
- ECU Tune: A proper ECU tune can optimize fuel maps and ignition timing, unlocking additional power and efficiency.
- Boost Controller: An electronic or manual boost controller allows you to adjust boost levels, providing more power when needed.
- Upgraded Fuel Pump: A higher-capacity fuel pump ensures adequate fuel delivery, especially when running higher boost levels.
Cold Air Intake Systems
Installing a cold air intake is one of the simplest and most effective ways to enhance your 4G63’s performance. By drawing cooler air from outside the engine bay, these systems improve the engine’s air-fuel mixture.
- Improved throttle response
- Potential horsepower gains of 5-15 HP
- Easy installation with minimal tools
Intercooler Upgrades
For turbocharged 4G63 engines, upgrading the intercooler can significantly enhance performance. A larger intercooler provides better cooling for the compressed air, resulting in more power and efficiency.
- Reduces intake temperatures
- Improves air density
- Can support higher boost levels without knock
Exhaust System Upgrades
A high-performance exhaust system helps your 4G63 breathe better. By reducing back pressure and improving exhaust flow, you can unlock additional horsepower.
- Cat-back exhaust systems are popular for their balance of sound and performance.
- Header upgrades can provide additional gains by improving exhaust flow from the engine.
- Look for options that provide a deep, aggressive tone without being overly loud.
ECU Tuning
One of the most crucial modifications for maximizing the performance of your 4G63 is a proper ECU tune. This process adjusts various parameters to improve overall engine performance.
- Optimizes air-fuel ratios for better combustion
- Increases boost levels safely
- Can improve fuel economy while increasing power
Boost Controllers
Using a boost controller allows you to manage the amount of boost pressure generated by your turbocharger. This control can lead to significant performance improvements.
- Manual boost controllers are generally more affordable and easy to install.
- Electronic boost controllers offer more precise adjustments and features.
- Boost control can help prevent engine knock and enhance reliability.
Fuel Pump Upgrades
When increasing boost and power levels, it’s essential to ensure your engine receives enough fuel. Upgrading your fuel pump can help meet the demands of higher performance.
- Look for pumps rated for higher flow rates.
- Ensure compatibility with your existing fuel system.
- Consider upgrading your fuel injectors simultaneously for optimal results.
Conclusion
Maximizing the performance of your 4G63 engine in an Eclipse doesn’t have to break the bank. By implementing these affordable supporting modifications, you can significantly enhance your vehicle’s performance, making it a more enjoyable driving experience. Always remember to research and choose quality parts to ensure reliability and longevity in your upgrades.
