Turbocharging the 4G63 engine is a popular modification among automotive enthusiasts looking for increased power and performance. This engine, known for its robust design, can greatly benefit from the right combination of components. In this article, we will explore the best wastegates, intercoolers, and exhaust systems to turbocharge your 4G63 effectively, ensuring both power and reliability.
Understanding the 4G63 Engine
The 4G63 engine is a four-cylinder, 2.0-liter powerplant developed by Mitsubishi. It is famous for its use in various models, including the Mitsubishi Eclipse and Lancer Evolution. Known for its durability and tuning potential, the 4G63 can handle significant power increases when properly modified.
Choosing the Right Wastegate
A wastegate is a critical component in a turbocharged system, controlling the amount of exhaust gas that enters the turbine. Proper selection of a wastegate can enhance boost control and prevent overboosting, which can damage the engine.
- External Wastegates: These are mounted separately from the turbo and provide better boost control. Popular choices include the Tial MVS and Turbosmart HyperGate.
- Internal Wastegates: Integrated into the turbo, these are easier to install but may offer less precise control. The OEM wastegate actuator can be upgraded for better performance.
Best Intercoolers for the 4G63
Intercoolers play a vital role in cooling the compressed air from the turbocharger before it enters the engine. Cooler air is denser and contains more oxygen, leading to improved combustion and performance.
- Front-Mount Intercoolers: These are larger and more efficient, allowing for greater cooling capacity. Brands like Mishimoto and ETS offer high-quality options.
- Side-Mount Intercoolers: More compact and easier to install, these are suitable for those with limited space. Options include the Dejon Tool and OEM upgrades.
Top Exhaust Systems for Performance
The exhaust system is crucial for turbocharged engines, as it affects back pressure and overall performance. A well-designed exhaust can help maximize power output and improve throttle response.
- Cat-Back Exhaust Systems: These systems replace the exhaust from the catalytic converter back, improving flow and sound. Popular brands include Apexi and Greddy.
- Downpipes: Upgrading the downpipe can significantly reduce turbo lag and improve power. Look for options from companies like VRSF and Megan Racing.
Combining Components for Maximum Effect
When turbocharging a 4G63, it’s essential to consider how each component works together. The right combination of wastegate, intercooler, and exhaust system can lead to optimal performance.
- Boost Control: Ensure your wastegate can handle the desired boost levels without fluttering or opening prematurely.
- Cooling Efficiency: The intercooler should be sized appropriately for your power goals, providing enough cooling to maintain performance.
- Exhaust Flow: A free-flowing exhaust system will help the turbo spool faster and improve overall engine efficiency.
Conclusion
Turbocharging a 4G63 engine can unlock significant power and performance potential. By carefully selecting the right wastegate, intercooler, and exhaust system, enthusiasts can create a reliable and powerful setup that enhances their driving experience. With the right components, the 4G63 can truly shine in any performance application.
