The 4G63 engine, known for its performance potential, is a popular choice among automotive enthusiasts. Achieving 450 horsepower from this engine requires a combination of turbo upgrades, ECU tuning, and fuel modifications. This article will guide you through the essential steps to reach this power goal.
Understanding the 4G63 Engine
The 4G63 is a 2.0L inline-4 engine that has gained fame in the Mitsubishi community. Its robust design and lightweight construction make it an excellent candidate for tuning. To reach higher horsepower levels, several modifications are necessary.
Turbo Upgrades
One of the most significant contributors to increased horsepower is upgrading the turbocharger. Here are some popular options:
- Big 16G Turbo: A common upgrade that provides a good balance of power and response.
- Green Turbo: Known for its ability to support higher horsepower levels while maintaining efficiency.
- FP Black Turbo: A larger turbo that can push the 4G63 to its limits, ideal for reaching 450 hp.
When selecting a turbo, consider the following factors:
- Boost levels
- Response time
- Compatibility with existing components
Supporting Modifications
To maximize the benefits of a turbo upgrade, additional modifications are necessary:
- Upgraded Intercooler: Helps reduce intake temperatures for better performance.
- Exhaust System: A high-flow exhaust system reduces back pressure and enhances turbo efficiency.
- Intake System: An upgraded intake allows for better airflow to the engine.
ECU Tuning
Once the turbo and supporting modifications are in place, ECU tuning is essential to optimize performance. Tuning adjusts fuel maps, ignition timing, and boost levels to ensure the engine runs efficiently.
Tuning Options
There are several tuning solutions available for the 4G63:
- Standalone ECU: Provides complete control over engine parameters but requires advanced knowledge.
- ECU Reflash: Modifies the factory ECU settings for improved performance.
- Piggyback Systems: Adds to the factory ECU without replacing it, offering a balance of control and cost.
Choosing the Right Tuner
Selecting an experienced tuner is crucial. Look for someone with a proven track record on 4G63 engines and positive reviews from the community.
Fuel Modifications
To support the increased power levels, upgrading the fuel system is critical. Here are the main components to consider:
- Fuel Injectors: Larger injectors are necessary to provide the increased fuel flow required for higher horsepower.
- Fuel Pump: An upgraded fuel pump ensures adequate fuel delivery under high demand.
- Fuel Pressure Regulator: Helps maintain consistent fuel pressure for optimal performance.
Choosing the Right Components
When selecting fuel system components, ensure compatibility with your turbo setup and power goals. Consult with experts or forums for recommendations.
Final Considerations
After completing the turbo upgrades, ECU tuning, and fuel modifications, it’s essential to conduct thorough testing. Monitor engine parameters to ensure everything operates smoothly and efficiently.
Reaching 450 horsepower on a 4G63 is an achievable goal with the right approach and components. By following these guidelines, you can unlock the full potential of your engine and enjoy the exhilarating performance it offers.
