The Mitsubishi Eclipse GST has long been a favorite among car enthusiasts for its blend of performance and affordability. With the right modifications, it can transform into a powerhouse on the streets. This article delves into the real-world results of a 400 horsepower Eclipse GST, focusing on custom tuning and an upgraded fuel system.
Understanding the Mitsubishi Eclipse GST
The Mitsubishi Eclipse GST, produced from the mid-1990s to early 2000s, features a turbocharged inline-4 engine. Known for its lightweight construction and agile handling, the GST variant is a popular choice for tuning enthusiasts. However, achieving higher horsepower requires careful consideration of both tuning and fuel delivery systems.
Key Modifications for Achieving 400 HP
- Custom Engine Tuning
- Upgraded Fuel System
- Performance Exhaust System
- High-Performance Turbocharger
- Upgraded Intercooler
Custom Engine Tuning
Custom engine tuning is essential for maximizing horsepower. By adjusting the air-fuel ratio, ignition timing, and boost levels, tuners can unlock the full potential of the engine. A professional tuner uses a dynamometer to ensure that the vehicle runs efficiently and safely at higher power levels.
Upgraded Fuel System
The stock fuel system in the Eclipse GST may not support the demands of a 400 hp setup. Upgrading the fuel pump, injectors, and fuel lines is crucial to provide adequate fuel flow and pressure. This ensures that the engine receives the necessary fuel to match the increased air intake from the turbocharger.
Performance Exhaust System
A performance exhaust system reduces back pressure and improves exhaust flow. This modification allows the engine to expel gases more efficiently, which is vital for achieving higher horsepower. A cat-back exhaust system is a popular choice among Eclipse owners looking to enhance performance.
High-Performance Turbocharger
Upgrading to a high-performance turbocharger is one of the most effective ways to increase horsepower. A larger turbocharger can provide more boost, allowing for greater power output. However, it is essential to choose a turbo that matches the engine’s capabilities and the desired power goals.
Upgraded Intercooler
As the turbocharger compresses air, it also increases its temperature. An upgraded intercooler helps to cool the compressed air before it enters the engine, resulting in denser air and improved combustion. This modification is crucial for maintaining performance and preventing engine knock.
Real-World Performance Results
After implementing these modifications, the Eclipse GST achieves impressive performance results. Dyno tests reveal that the vehicle reaches 400 horsepower at the wheels, providing exhilarating acceleration and responsiveness.
Acceleration and Speed
With the increased horsepower, the Eclipse GST can accelerate from 0 to 60 mph in under 5 seconds. This level of performance rivals many modern sports cars, showcasing the potential of a well-tuned Eclipse.
Handling and Stability
Upgraded suspension components, such as coilovers and sway bars, enhance the handling characteristics of the vehicle. This ensures that the Eclipse remains stable during high-speed maneuvers, allowing drivers to enjoy the full potential of the power increase.
Conclusion
Achieving 400 horsepower in a Mitsubishi Eclipse GST is an exciting journey that requires careful planning and execution. By focusing on custom tuning and upgrading the fuel system, enthusiasts can unlock the true potential of their vehicles. The results are not just numbers on a dyno; they translate into an exhilarating driving experience that keeps the spirit of performance alive.
