The 4G63 engine, known for its performance in the Mitsubishi Eclipse, has become a favorite among drag racing enthusiasts. With the right modifications, this engine can deliver impressive power gains and enhance your vehicle’s suspension setup for optimal performance on the track.
Understanding the 4G63 Engine
The 4G63 is a turbocharged inline-four engine that has proven itself in both street and racing applications. It was originally designed for the Mitsubishi Lancer Evolution and later adapted for the Eclipse. Its robust design allows for significant tuning potential, making it an ideal candidate for drag racing modifications.
Power Gains: Essential Modifications
To maximize the power output of your 4G63 engine, consider the following modifications:
- Turbo Upgrade: Replacing the stock turbocharger with a larger unit can significantly increase horsepower and torque.
- ECU Tuning: Custom tuning of the engine control unit (ECU) can optimize fuel maps and ignition timing for enhanced performance.
- Intake and Exhaust Systems: Upgrading to a high-flow intake and exhaust system reduces back pressure and improves airflow, leading to better performance.
- Intercooler Upgrade: A larger intercooler helps reduce intake temperatures, allowing for denser air and improved combustion efficiency.
- Fuel System Upgrades: Installing larger fuel injectors and a high-flow fuel pump ensures the engine receives adequate fuel for increased power levels.
Suspension Setup for Drag Racing
A proper suspension setup is crucial for drag racing, as it affects traction and handling. Here are key components to consider:
- Adjustable Coilovers: These allow for precise height adjustment and damping settings to optimize weight transfer during launches.
- Stiffer Springs: Upgrading to stiffer springs can help reduce body roll and improve stability during acceleration.
- Performance Shock Absorbers: High-quality shocks improve handling and control, especially during hard launches.
- Rear Traction Bars: These help to improve traction by reducing wheel hop, allowing for more effective power transfer to the ground.
- Upgraded Sway Bars: Stiffer sway bars can enhance cornering performance and stability, important for maintaining control at high speeds.
Additional Modifications for Enhanced Performance
Beyond the basics, several additional modifications can further enhance your 4G63’s performance:
- Weight Reduction: Removing unnecessary components can improve acceleration and overall performance.
- High-Performance Clutch: Upgrading to a high-performance clutch can handle increased power and provide better engagement.
- Lightweight Wheels: Reducing unsprung weight with lightweight wheels can improve acceleration and handling.
- Brake Upgrades: Enhanced braking systems are essential for safely managing increased speeds.
- Data Logging Tools: Using data logging can help track performance metrics and optimize tuning further.
Conclusion
With the right modifications, the 4G63 engine can be transformed into a drag racing powerhouse. Focus on power gains through turbo upgrades, ECU tuning, and enhanced airflow, while ensuring your suspension setup is optimized for traction and stability. By investing in these modifications, you can significantly improve your vehicle’s performance on the drag strip.
