The Mitsubishi Eclipse, particularly the models equipped with the 4G63 engine, has garnered a reputation for performance and tuning potential. However, like any vehicle, the reliability of the 4G63 can be enhanced through strategic upgrades using both OEM and aftermarket parts. This article will explore various modifications and replacements that can help improve the longevity and dependability of your 4G63 Eclipse.
Understanding the 4G63 Engine
The 4G63 engine is a 2.0-liter inline-four engine that has been a favorite among car enthusiasts since its introduction in the late 1980s. Known for its turbocharged variants, the 4G63 is celebrated for its robust design and tuning capabilities. However, to maintain its performance and reliability, specific upgrades are often necessary.
OEM Parts for Reliability
OEM (Original Equipment Manufacturer) parts are designed to meet the specifications of the original vehicle. They ensure compatibility and reliability, making them a preferred choice for many upgrades.
- OEM Timing Belt: Replacing the timing belt at regular intervals is crucial to prevent engine failure.
- OEM Water Pump: A reliable water pump is essential for maintaining engine temperature and preventing overheating.
- OEM Fuel Injectors: Using OEM fuel injectors ensures optimal fuel delivery and engine performance.
- OEM Engine Mounts: Upgrading to new OEM engine mounts can reduce vibrations and improve handling.
Aftermarket Upgrades for Enhanced Performance
Aftermarket parts can provide performance enhancements that OEM parts may not offer. However, it is essential to choose high-quality components to ensure reliability.
- Aftermarket Exhaust System: Upgrading to a performance exhaust system can improve airflow, leading to better engine performance.
- Upgraded Intercooler: A larger intercooler can help lower intake temperatures, improving engine efficiency and power.
- Performance Fuel Pump: An aftermarket fuel pump can provide increased fuel flow, supporting higher horsepower applications.
- ECU Tune: A custom ECU tune can optimize engine performance, enhancing throttle response and power delivery.
Suspension and Handling Upgrades
Improving the suspension and handling of your Eclipse can significantly enhance its reliability and driving experience. Here are some upgrades to consider:
- Upgraded Coilovers: Adjustable coilovers allow for better handling and ride quality, adapting to various driving conditions.
- Strut Tower Brace: Installing a strut tower brace can increase chassis rigidity, improving handling during cornering.
- Performance Sway Bars: Upgrading sway bars can reduce body roll, enhancing stability in turns.
- High-Performance Tires: Investing in quality tires improves grip and overall handling, crucial for high-performance driving.
Braking System Enhancements
Reliable braking is essential for safety and performance. Upgrading the braking system should be a priority for any 4G63 Eclipse owner looking to enhance reliability.
- Performance Brake Pads: Upgrading to high-performance brake pads can improve stopping power and reduce brake fade.
- Slotted or Drilled Rotors: These rotors enhance heat dissipation and improve braking performance under heavy use.
- Stainless Steel Brake Lines: These lines provide a firmer brake pedal feel and reduce expansion under pressure.
- Upgraded Master Cylinder: A larger master cylinder can improve brake fluid pressure, enhancing overall braking performance.
Regular Maintenance for Longevity
While upgrades are essential, regular maintenance is crucial for the longevity of your 4G63 engine. Here are some maintenance tips:
- Regular Oil Changes: Change the oil every 3,000 to 5,000 miles to keep the engine running smoothly.
- Inspect Belts and Hoses: Regularly check for wear and replace any damaged components.
- Monitor Fluid Levels: Keep an eye on coolant, brake fluid, and transmission fluid levels to prevent issues.
- Routine Inspections: Have the vehicle inspected regularly to catch any potential problems early.
Conclusion
Enhancing the reliability of your 4G63 Eclipse involves a combination of OEM and aftermarket upgrades, along with regular maintenance. By investing in quality parts and staying on top of maintenance, you can ensure that your Eclipse remains a reliable and enjoyable vehicle for years to come.
