The 4G63 engine, renowned for its performance potential, is a popular choice among car enthusiasts, especially in the Mitsubishi Eclipse. When pushing the limits of this engine, particularly at high power levels, it becomes essential to upgrade not only the engine components but also the transmission and drivetrain. This article explores the necessary supporting modifications to ensure reliability and performance.
Understanding the 4G63 Engine
The 4G63 is a turbocharged inline-four engine that has gained a reputation for its robust performance and tunability. Originally used in the Mitsubishi Eclipse, it has become a favorite for modifications due to its potential for high power outputs. However, as power levels increase, the strain on the transmission and drivetrain also rises, necessitating upgrades.
Why Upgrade the Transmission?
The transmission is a critical component that transfers power from the engine to the wheels. When increasing power levels, the stock transmission may not handle the added stress, leading to potential failures. Upgrading the transmission helps maintain performance and reliability.
Key Transmission Upgrades
- Short-Throw Shifter: Improves shifting speed and precision.
- Heavy-Duty Clutch: Capable of handling increased torque and power.
- Transmission Cooler: Helps maintain optimal temperatures during high-performance driving.
- Gear Set Upgrades: Allows for better power delivery and acceleration.
Drivetrain Upgrades for Enhanced Performance
The drivetrain consists of various components that work together to deliver power to the wheels. Upgrading these components is crucial when increasing the engine’s output to ensure that power is efficiently transferred without damaging any parts.
Essential Drivetrain Modifications
- Upgraded Axles: Stronger axles can withstand higher torque and reduce the risk of breakage.
- Limited-Slip Differential: Improves traction and stability, especially during hard acceleration.
- Driveshaft Upgrade: A lightweight, stronger driveshaft can enhance performance and reduce rotational mass.
- Suspension Enhancements: Upgraded suspension components can improve handling and power transfer to the ground.
Choosing the Right Parts
When selecting parts for transmission and drivetrain upgrades, it is essential to consider quality and compatibility. High-quality aftermarket parts can provide better performance and longevity compared to stock components. Here are some recommendations:
- Brands to Consider: Look for reputable brands known for performance parts.
- Reviews and Recommendations: Research user reviews and seek recommendations from fellow enthusiasts.
- Compatibility: Ensure all parts are compatible with the 4G63 engine and your specific model of Eclipse.
Installation and Tuning
Proper installation of transmission and drivetrain upgrades is crucial for performance and reliability. It is advisable to consult with professionals or experienced mechanics to ensure that all components are installed correctly. Additionally, tuning may be necessary to optimize the engine’s performance with the new upgrades.
Importance of Professional Help
While some enthusiasts may choose to perform upgrades themselves, professional installation can help avoid common pitfalls. Experts can provide insights on the best practices and ensure that everything is functioning as intended.
Conclusion
Upgrading the transmission and drivetrain of a 4G63 Eclipse is essential for those looking to increase power levels significantly. By investing in quality parts and professional installation, enthusiasts can enjoy enhanced performance and reliability, allowing their vehicles to reach their full potential.
