The 4G63 engine, known for its performance and tuning potential, is a popular choice among automotive enthusiasts, especially in turbocharged builds. However, to ensure reliability and longevity, specific considerations must be taken into account. This article will explore essential tips regarding oil cans, piston strength, and cooling systems to optimize your 4G63 turbo build.
Understanding the 4G63 Engine
The 4G63 engine is a four-cylinder, turbocharged powerhouse that has made its mark in the automotive world. Originally designed for the Mitsubishi Eclipse, it has been utilized in various applications. Understanding its design and common issues is crucial for building a reliable turbocharged version.
Key Features of the 4G63
- DOHC (Dual Overhead Camshaft) configuration
- Iron block and aluminum head for durability
- Intercooled turbocharging capability
Oil Cans: Importance and Upgrades
Oil management is critical in any turbocharged engine. The 4G63’s oil can design can significantly affect the engine’s reliability under high-stress conditions.
Stock Oil Can Limitations
The stock oil can may not provide sufficient capacity or cooling for high-performance applications. Increased oil temperatures can lead to premature engine wear.
Recommended Upgrades
- Upgrade to a larger capacity oil can to improve oil flow.
- Consider baffled oil cans to prevent oil starvation during hard cornering.
- Use high-quality oil with adequate viscosity for turbo applications.
Piston Strength: Choosing the Right Components
Pistons play a vital role in the performance and reliability of the 4G63 turbo build. The right choice can withstand the pressures of turbocharging.
Stock Pistons vs. Aftermarket Options
While stock pistons can handle moderate power levels, they may not be suitable for high boost applications. Upgrading to forged pistons can significantly enhance reliability.
Key Considerations for Piston Selection
- Choose forged pistons for increased strength and durability.
- Ensure proper compression ratio for your specific turbo setup.
- Consider piston coatings to reduce friction and improve longevity.
Cooling Systems: Maintaining Optimal Temperatures
Effective cooling is essential for maintaining engine performance and preventing overheating, especially in turbocharged applications.
Stock Cooling Limitations
The stock cooling system may struggle to keep temperatures in check during high-performance driving. Upgrades are often necessary for reliability.
Cooling System Upgrades
- Install a larger radiator to improve heat dissipation.
- Upgrade to a high-performance water pump for better coolant flow.
- Consider adding an oil cooler to manage oil temperatures effectively.
Conclusion: Building a Reliable 4G63 Turbo
Building a reliable 4G63 turbo engine requires careful attention to oil management, piston strength, and cooling systems. By implementing the tips discussed in this article, enthusiasts can enhance the performance and longevity of their builds. Proper upgrades and maintenance are key to enjoying the full potential of the 4G63 turbocharged experience.
