The 4G63 engine, famously used in the Mitsubishi Eclipse, offers a robust platform for turbocharging enthusiasts. By upgrading components like intercoolers and boost control systems, you can significantly enhance performance while ensuring engine safety. This article delves into the best intercoolers and boost control options for the 4G63 Eclipse.
Understanding the 4G63 Engine
The 4G63 is a 2.0L inline-4 engine known for its turbocharged variants used in various Mitsubishi models. Its design allows for substantial power upgrades, making it a popular choice among tuners. Before diving into upgrades, it’s essential to understand the engine’s capabilities and limitations.
Importance of Intercoolers
Intercoolers play a crucial role in turbocharged engines by cooling the air entering the engine, which helps improve performance and efficiency. A well-chosen intercooler can lead to higher power outputs and better engine safety.
Types of Intercoolers
- Front Mount Intercoolers (FMIC): These are mounted at the front of the vehicle, allowing for maximum airflow and cooling efficiency.
- Top Mount Intercoolers (TMIC): Positioned above the engine, these are more compact but may not cool as effectively as FMICs.
Best Intercoolers for 4G63 Eclipse
- AMS Performance Front Mount Intercooler: Known for its high-quality construction and excellent cooling capabilities, it’s a top choice for power seekers.
- Greddy Front Mount Intercooler Kit: This kit includes all necessary components for installation and offers great performance improvements.
- DeatschWerks Top Mount Intercooler: A great option for those with limited space, providing solid cooling without sacrificing performance.
Boost Control Systems
Boost control systems are essential for managing the amount of boost pressure produced by the turbocharger. Proper control ensures that the engine operates within safe limits while maximizing performance.
Types of Boost Control Systems
- Manual Boost Controllers: Simple and cost-effective, these allow drivers to adjust boost levels manually.
- Electronic Boost Controllers: These provide more precise control over boost levels and can adjust in real-time based on engine conditions.
Best Boost Control Options for 4G63 Eclipse
- Hallman Pro Boost Controller: A highly rated manual boost controller known for its reliability and ease of use.
- AEM Tru-Boost Controller: An electronic boost controller that offers advanced features, including data logging and adjustable boost levels.

Balancing Power and Safety
While increasing power is the goal, it’s crucial to maintain engine safety. Upgrading your intercooler and boost control must be complemented by other modifications to ensure reliability.
Supporting Modifications
- Fuel System Upgrades: Ensure your fuel pump and injectors can handle increased power levels.
- Engine Management: A standalone engine management system can optimize fuel mapping and ignition timing for increased performance.
- Exhaust System: Upgrading to a high-flow exhaust system can reduce back pressure and improve turbo response.
Conclusion
Turbocharging a 4G63 Eclipse can lead to significant performance gains when done correctly. Choosing the right intercooler and boost control system is vital for achieving power while ensuring safety. By balancing upgrades and focusing on supporting modifications, you can enjoy a powerful and reliable turbocharged experience.
