The 4G63 engine is a legendary powerplant known for its performance potential. With the right upgrades, reaching 400 horsepower is achievable, especially when utilizing HKS components and supporting mods. This guide will provide a comprehensive overview of the necessary steps and components to achieve this goal.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine produced by Mitsubishi. It has been used in various models, most notably the Mitsubishi Eclipse, Talon, and Galant VR-4. Its robust design and turbocharged configuration make it a favorite among tuners.
Key Components for a 400 HP Build
- HKS Turbocharger
- HKS Wastegate
- HKS Intercooler
- HKS Exhaust System
- Upgraded Fuel System
- ECU Tuning
HKS Turbocharger
The HKS turbocharger is critical for achieving high horsepower. Opt for a model that can support your power goals while maintaining reliability. The HKS GT series is a popular choice among enthusiasts.
HKS Wastegate
A reliable wastegate is necessary to control boost levels effectively. The HKS wastegate will help prevent boost creep and ensure that your turbo operates within safe parameters.
HKS Intercooler
To maximize performance, an upgraded intercooler is essential. The HKS intercooler will help reduce intake temperatures, allowing for more efficient combustion and preventing knock.
HKS Exhaust System
An HKS exhaust system will improve exhaust flow, reducing back pressure and allowing the turbo to spool faster. This upgrade is crucial for achieving the desired horsepower.
Supporting Mods for Maximum Performance
- Upgraded Fuel Injectors
- High-Flow Fuel Pump
- Performance Engine Management
- Upgraded Camshafts
- Stronger Pistons and Rods
Upgraded Fuel Injectors
To support higher horsepower, you will need larger fuel injectors. Choose injectors that can deliver the necessary fuel flow for your power goals, typically in the range of 750cc or larger.
High-Flow Fuel Pump
A high-flow fuel pump is essential for maintaining the required fuel pressure under high-load conditions. Ensure your pump can support your horsepower target without any issues.
Performance Engine Management
Proper tuning is vital. An aftermarket engine management system will allow for precise control over fuel delivery and ignition timing, optimizing performance and reliability.
Upgraded Camshafts
Installing upgraded camshafts can improve airflow and increase power. Look for cam profiles that complement your turbo setup for the best results.
Stronger Pistons and Rods
To handle the increased power, consider upgrading to forged pistons and connecting rods. These components will provide the strength needed to withstand higher boost levels and prevent engine failure.
Additional Considerations
- Cooling System Upgrades
- Transmission Strengthening
- Proper Tuning
Cooling System Upgrades
As power increases, so does heat. Upgrading your cooling system with a larger radiator and improved fans will help maintain optimal engine temperatures during operation.
Transmission Strengthening
With increased horsepower, the transmission may require strengthening to handle the additional torque. Consider upgrading to a stronger clutch and transmission components to ensure reliability.
Proper Tuning
Finally, proper tuning is essential to achieving your horsepower goals safely. Work with a professional tuner who understands the 4G63 and can optimize your setup for both performance and reliability.
Conclusion
Building a 4G63 to reach 400 horsepower is an exciting project that requires careful planning and the right components. By utilizing HKS parts and supporting mods, you can achieve impressive performance while maintaining reliability. Always remember to prioritize tuning and component quality for the best results.
