The Mitsubishi Eclipse GST is a beloved vehicle among car enthusiasts, known for its turbocharged engine and potential for tuning. If you’re looking to maximize your Eclipse GST’s power and achieve gains of 300-350 horsepower, there are several upgrades that can help you reach that goal. This article will explore the top upgrades that can enhance your vehicle’s performance.
Understanding the Basics of Power Upgrades
Before diving into specific upgrades, it’s essential to understand the components that contribute to your vehicle’s horsepower. The main areas to focus on include the engine, exhaust system, intake system, and tuning. Optimizing these elements will help you achieve the desired power gains.
Essential Upgrades for 300-350 HP Gains
- Turbocharger Upgrade: Upgrading to a larger turbocharger can significantly increase your engine’s airflow, allowing for more power.
- Intercooler Upgrade: A high-performance intercooler can help lower intake temperatures, improving engine efficiency and performance.
- Exhaust System Upgrade: A free-flowing exhaust system reduces back pressure and enhances exhaust flow, contributing to power gains.
- Intake System Upgrade: A performance intake system allows for better airflow into the engine, maximizing combustion efficiency.
- ECU Tuning: Custom tuning of your engine’s ECU can optimize fuel maps and timing, unlocking additional horsepower.
- Fuel System Upgrade: Upgrading fuel injectors and fuel pumps ensures that your engine receives the necessary fuel for increased power levels.
- Performance Camshafts: Installing aftermarket camshafts can improve airflow and increase horsepower by optimizing valve timing.
Detailed Breakdown of Each Upgrade
Turbocharger Upgrade
A larger turbocharger can provide a significant boost in power by increasing the amount of air entering the engine. Consider options like the Garrett GT28 or the Precision 5858 turbo for optimal performance. These upgrades can help you reach your horsepower goals while maintaining reliability.
Intercooler Upgrade
Installing a high-performance intercooler, such as a front-mount intercooler, can lower the temperature of the air entering the engine. Cooler air is denser, allowing for better combustion and increased power output. Brands like Mishimoto and ETS offer excellent options for the Eclipse GST.
Exhaust System Upgrade
A performance exhaust system, including a high-flow catalytic converter and cat-back exhaust, can significantly improve exhaust flow. This upgrade reduces back pressure and allows the turbo to spool more quickly, enhancing overall performance. Look for systems from brands like Greddy or HKS for quality options.
Intake System Upgrade
Upgrading to a performance intake system can dramatically improve airflow into the engine. Cold air intakes from brands like AEM or K&N can provide a noticeable increase in horsepower by ensuring that the engine receives cooler, denser air.
ECU Tuning
Custom ECU tuning is crucial for maximizing the potential of your upgrades. A professional tune can adjust fuel maps, ignition timing, and boost levels to ensure that your engine runs efficiently and safely at higher power levels. Consider using tuning software like ECUFlash or a reputable tuner for this task.
Fuel System Upgrade
To support increased power levels, upgrading your fuel system is essential. Larger fuel injectors and a high-flow fuel pump will ensure that your engine receives the necessary fuel. Brands like DeatschWerks and Walbro offer reliable options that can handle higher horsepower demands.
Performance Camshafts
Installing performance camshafts can improve engine airflow and increase horsepower by optimizing valve timing. Look for camshafts designed specifically for turbocharged applications to maximize gains without sacrificing drivability.
Conclusion
Maximizing the power of your Mitsubishi Eclipse GST requires a combination of upgrades focused on enhancing airflow, fuel delivery, and engine tuning. By investing in a larger turbocharger, intercooler, exhaust system, intake system, ECU tuning, fuel system, and camshafts, you can achieve impressive gains of 300-350 horsepower. Always ensure that these upgrades are installed correctly and tuned properly to enjoy the full benefits while maintaining reliability.
