The quest for high horsepower in the automotive world has led many enthusiasts to explore unconventional methods and components. One of the most exciting builds in recent years is the high-end 4G63 Eclipse race build, which aims to achieve over 700 horsepower using go-kart pistons and a custom billet manifold.
Understanding the 4G63 Engine
The 4G63 engine, a turbocharged inline-four, has become a favorite among tuners and racers. Known for its robust design and potential for high power output, this engine has powered various Mitsubishi models, including the Eclipse. To reach the ambitious goal of 700+ horsepower, modifications are essential.
Key Components of the Build
- Go-Kart Pistons
- Custom Billet Manifold
- Upgraded Turbocharger
- High-Performance Fuel System
- Enhanced Engine Management System
Go-Kart Pistons
Using go-kart pistons in a 4G63 build might seem unconventional, but these lightweight components can significantly reduce reciprocating mass. This reduction allows for quicker revs and improved throttle response, essential for achieving high horsepower levels.
Custom Billet Manifold
A custom billet manifold is crucial for optimizing airflow into the engine. This component is designed to maximize the efficiency of the turbocharger and improve overall performance. A well-designed manifold can help achieve better boost control and enhance power delivery across the RPM range.
Supporting Modifications
To support the high power output, several additional modifications are necessary. These include an upgraded turbocharger, a high-performance fuel system, and an enhanced engine management system.
Upgraded Turbocharger
The heart of any high-power build is the turbocharger. For the 4G63, selecting a turbo that can handle high boost levels while maintaining reliability is paramount. Options like the Garrett GT series or BorgWarner EFR series are popular choices among tuners.
High-Performance Fuel System
To support increased horsepower, the fuel system must also be upgraded. This includes larger fuel injectors, a high-flow fuel pump, and a fuel pressure regulator. Ensuring that the engine receives adequate fuel is critical for performance and reliability.
Enhanced Engine Management System
The engine management system plays a crucial role in tuning for high horsepower. A standalone engine management system allows for precise control over fuel maps, ignition timing, and boost levels. This level of control is essential for maximizing performance while maintaining engine safety.
Building for Reliability
While achieving 700+ horsepower is an exciting goal, reliability should never be overlooked. Proper engine tuning, regular maintenance, and using quality components are vital to ensure the longevity of the build.
Regular Maintenance
High-performance engines require more frequent maintenance checks. Regular oil changes, checking for boost leaks, and monitoring fuel quality are essential practices to keep the engine running smoothly.
Quality Components
Investing in quality components can save time and money in the long run. Components that are designed to handle high stress and heat will contribute to the overall reliability of the engine build.
Conclusion
Achieving over 700 horsepower in a 4G63 Eclipse race build is a challenging yet rewarding endeavor. By utilizing go-kart pistons, a custom billet manifold, and supporting modifications, enthusiasts can push the limits of performance. With careful planning and execution, this build can deliver thrilling power and speed on the track.
