The 4G63 turbo motor has earned a reputation among car enthusiasts for its potential to produce impressive horsepower figures. Whether you’re a seasoned racer or a weekend warrior, upgrading your 4G63 to reach the coveted 350 horsepower mark is an exciting journey. In this article, we will explore essential upgrades that can help you achieve this goal while ensuring reliability and performance.
Understanding the 4G63 Turbo Motor
The 4G63 engine is a 2.0-liter inline-four engine produced by Mitsubishi. It is well-known for its use in various models, including the Mitsubishi Eclipse, Eagle Talon, and Mitsubishi Galant. The turbocharged version of this engine is particularly popular due to its robust design and tuning potential.
Key Upgrades to Reach 350 HP
1. Turbocharger Upgrade
The factory turbocharger on the 4G63 can limit power output. Upgrading to a larger turbocharger is one of the most effective ways to increase horsepower. Consider options like the Garret GT30 or a BorgWarner EFR turbo for better flow and efficiency.
2. Fuel System Enhancements
To support the increased airflow from a larger turbo, an upgraded fuel system is essential. This includes:
- High-flow fuel injectors (at least 550cc)
- Upgraded fuel pump to maintain pressure
- Fuel pressure regulator for optimal performance
3. Engine Management System
A reliable engine management system (EMS) is crucial for tuning your 4G63. Upgrading to a standalone EMS, such as the AEM Infinity or MegaSquirt, allows for precise tuning and control over fuel and ignition maps.
4. Exhaust System Upgrade
Enhancing the exhaust system is vital for reducing back pressure and improving turbo spool. Consider the following:
- 3-inch turbo-back exhaust system
- High-flow catalytic converter or test pipe
- Upgraded muffler for better sound and flow
5. Intercooler Upgrade
To maximize performance, an upgraded intercooler is necessary to reduce intake temperatures. Look for a front-mount intercooler that provides sufficient cooling capacity and optimal airflow.
6. Internal Engine Components
For those pushing the limits, consider upgrading internal components to handle increased power. Key components include:
- Forged pistons for durability
- Aftermarket connecting rods
- Performance camshafts for improved airflow
7. Cooling System Improvements
Maintaining optimal engine temperatures is critical when increasing power. Upgrading the cooling system can include:
- High-capacity radiator
- Performance water pump
- Upgraded coolant hoses
Conclusion
Achieving 350 horsepower from your 4G63 turbo motor requires a combination of quality upgrades and careful tuning. By focusing on key areas such as the turbocharger, fuel system, and engine management, you can unlock the full potential of this iconic engine. Remember to balance performance with reliability to ensure a thrilling yet dependable driving experience.
