The Mitsubishi Eclipse G63 is a beloved platform among car enthusiasts, known for its lightweight design and turbocharged engine. Whether you’re looking to enhance your street performance or dominate the track, achieving 500 horsepower and beyond is an exciting challenge. This article will explore various modifications that can help you reach that power goal while maintaining reliability and drivability.
Understanding the G63 Platform
The G63 Eclipse is part of the Mitsubishi Eclipse family, specifically the models produced from 1995 to 1999. It features a turbocharged inline-four engine that can be modified significantly to increase power output. Understanding the basics of this platform is crucial for any modification strategy.
Essential Engine Mods for 500 HP
To achieve 500 horsepower, several key modifications to the engine are necessary. Here’s a list of essential components to consider:
- Upgraded Turbocharger: A larger turbo will help increase airflow and boost pressure.
- High-Performance Intercooler: To reduce intake temperatures and increase efficiency.
- Aftermarket Fuel Injectors: Higher flow rate injectors are essential for delivering the necessary fuel for increased power.
- Upgraded Fuel Pump: A high-performance fuel pump ensures adequate fuel delivery under high boost conditions.
- ECU Tune: A professional tune is crucial to optimize performance and ensure reliability.
Upgraded Turbocharger
Choosing the right turbocharger is vital for achieving your horsepower goals. Popular options include the Garrett GTX series or the BorgWarner EFR series, both known for their efficiency and performance.
High-Performance Intercooler
An aftermarket intercooler helps manage the heat generated by the turbo. Look for options that offer a larger core and better airflow, ensuring cooler intake temperatures for optimal performance.
Supporting Mods for Reliability
While increasing horsepower, it’s essential to consider supporting modifications that enhance reliability and drivability. Here are some recommendations:
- Upgraded Engine Internals: Forged pistons and rods can withstand higher power levels.
- Performance Camshafts: Upgraded cams can improve airflow and power delivery.
- Better Cooling System: An upgraded radiator and oil cooler help manage heat.
- Stronger Clutch: A high-performance clutch is necessary to handle the increased power.
- Exhaust System: A free-flowing exhaust reduces back pressure and enhances performance.
Upgraded Engine Internals
For those pushing the limits, consider forged internals. Brands like Wiseco and Eagle are popular choices for pistons and rods that can handle the stress of high horsepower.
Performance Camshafts
Upgrading to performance camshafts can significantly improve engine breathing. Look for cam profiles that enhance both low-end torque and top-end power.
Suspension and Handling Mods
To harness the power of your G63 Eclipse effectively, suspension and handling modifications are crucial. Here are some key upgrades:
- Coilover Suspension: Adjustable coilovers allow for fine-tuning ride height and handling characteristics.
- Upgraded Sway Bars: Stiffer sway bars reduce body roll and improve cornering stability.
- Performance Bushings: Upgrading to polyurethane bushings enhances responsiveness and reduces flex.
- Brakes: Upgraded brake pads and rotors are essential for stopping power at high speeds.
Coilover Suspension
Investing in a quality coilover suspension system allows for adjustable ride height and damping settings, providing the flexibility needed for both street and track use.
Upgraded Sway Bars
Stiffer sway bars minimize body roll during cornering, enhancing the overall handling dynamics of your Eclipse.
Aerodynamic Enhancements
Aerodynamics play a significant role in high-speed stability and performance. Consider these modifications:
- Front Splitter: Increases downforce at the front end, improving grip.
- Rear Spoiler: Helps stabilize the rear at high speeds, reducing lift.
- Side Skirts: Reduce airflow under the car, improving overall aerodynamics.
Front Splitter
A well-designed front splitter can significantly improve front-end grip, especially during cornering at high speeds.
Rear Spoiler
A rear spoiler not only adds style but also enhances stability by reducing aerodynamic lift, making the car more planted on the track.
Conclusion
Building a G63 Eclipse for 500 horsepower and beyond is an exciting journey that requires careful planning and execution. By focusing on essential engine mods, supporting modifications, suspension upgrades, and aerodynamic enhancements, you can create a well-rounded vehicle capable of excelling on both the street and the track. Remember to always prioritize reliability and safety in your build, ensuring that your Eclipse not only performs well but also remains enjoyable to drive.
