The 4G63 engine has a storied history in the world of performance tuning, especially for those looking to achieve over 500 horsepower. To ensure reliability at such power levels, upgrading the internals is crucial. This article will delve into the importance of using high-quality components like Arias pistons and Eagle rods to achieve this goal.
Understanding the 4G63 Engine
The 4G63 is a turbocharged inline-four engine that has powered various Mitsubishi models, notably the Eclipse and Lancer Evolution. Known for its robust design, it can handle significant power, but certain upgrades are necessary to maintain reliability at extreme outputs.
Why Upgrade Internals?
Upgrading the internals of the 4G63 engine is essential for several reasons:
- Increased Strength: Factory components may not withstand the stress at high horsepower levels.
- Improved Performance: Upgraded internals can enhance engine efficiency and responsiveness.
- Reliability: High-quality parts reduce the risk of catastrophic failure.
Arias Pistons: A Key Component
Arias pistons are a popular choice among performance enthusiasts for several reasons:
- Material Quality: Made from high-quality aluminum alloys, they offer excellent strength-to-weight ratios.
- Custom Options: Arias provides various compression ratios and designs tailored for specific builds.
- Thermal Management: Their design helps in better heat dissipation, crucial for high-performance applications.
Choosing the Right Compression Ratio
When selecting Arias pistons, it’s vital to consider the compression ratio. A lower compression ratio is often preferred for high boost applications, while a slightly higher ratio can improve efficiency. Consulting with a tuner can help in making the best choice.
Eagle Rods: Strength Meets Precision
Eagle rods are known for their durability and precision engineering. Here’s why they are an excellent choice for the 4G63:
- High-Strength Materials: Constructed from premium steel, Eagle rods can handle the increased stress of high horsepower.
- Lightweight Design: Their lightweight nature reduces reciprocating mass, allowing for faster engine response.
- Precision Machining: Ensures a perfect fit and alignment, minimizing the risk of failure.
Installation Considerations
When installing Eagle rods, it’s important to ensure proper torque specifications and clearances. This will help in achieving optimal performance and reliability. A professional engine builder should be consulted for installation.
Combining Arias Pistons and Eagle Rods
The combination of Arias pistons and Eagle rods creates a powerful synergy that enhances the overall performance of the 4G63 engine. Here’s how they work together:
- Balanced Performance: This pairing ensures that the engine can handle increased power without compromising reliability.
- Enhanced Boost Capability: Together, they allow for higher boost levels while maintaining engine integrity.
- Improved Engine Longevity: Quality components lead to less wear and tear, extending the life of the engine.
Conclusion
Upgrading the internals of the 4G63 engine with Arias pistons and Eagle rods is a critical step for anyone looking to achieve and maintain over 500 horsepower reliably. By investing in high-quality components, you can ensure that your engine performs at its best while minimizing the risk of failure.
For those considering this upgrade, thorough research and consultation with professionals are recommended to tailor the setup to your specific performance goals.
