The Mitsubishi Eclipse GSX is a beloved platform for car enthusiasts looking to enhance performance. With its turbocharged engine and all-wheel-drive system, the GSX provides a solid foundation for significant power upgrades. In this article, we will explore the top turbo upgrades that can help you achieve 350-450 horsepower, transforming your Eclipse into a high-performance machine.
Understanding the Basics of Turbocharging
Before diving into specific upgrades, it’s essential to understand how turbocharging works and the benefits it brings to your Eclipse GSX. A turbocharger uses exhaust gases to spin a turbine, which compresses air entering the engine. This process increases the amount of air and fuel that can be burned, resulting in more power.
Key Turbo Upgrades for Performance Enhancement
To achieve the desired horsepower gains, several key components can be upgraded. Below are the most effective turbo upgrades for the Eclipse GSX.
- Aftermarket Turbocharger
- Upgraded Intercooler
- Performance Exhaust System
- Tuning Software
- High-Performance Fuel Injectors
Aftermarket Turbocharger
One of the most impactful upgrades is the installation of an aftermarket turbocharger. Options such as the Garrett GT30 or the Precision 6266 can provide the necessary airflow to reach 350-450 hp. These turbochargers are designed to handle higher boost levels and improve throttle response.
Upgraded Intercooler
An upgraded intercooler is essential for maintaining optimal air temperatures and density. A larger front-mount intercooler can significantly reduce intake temperatures, allowing the engine to produce more power without the risk of knocking. Brands like Mishimoto and ETS offer excellent options for the GSX.
Performance Exhaust System
A high-performance exhaust system not only enhances the sound of your Eclipse but also improves exhaust flow. A 3-inch turbo-back exhaust system can reduce back pressure and help the turbo spool faster. Look for systems from reputable brands like Apexi or HKS.
Tuning Software
After upgrading your turbo and supporting components, proper tuning is crucial. Using tuning software such as ECMLink or DSMLink allows you to adjust fuel maps, ignition timing, and boost levels to maximize performance. A professional tune can help you safely reach your horsepower goals.
High-Performance Fuel Injectors
To support increased horsepower, high-performance fuel injectors are necessary. Upgrading to larger injectors, such as 750cc or 1000cc, ensures that your engine receives enough fuel to match the increased airflow from the turbocharger. This is vital for maintaining the correct air-fuel ratio.
Supporting Modifications for Reliability
While the above upgrades will significantly increase power, it’s essential to consider supporting modifications to maintain reliability. Here are some recommended upgrades:
- Upgraded Fuel Pump
- Stronger Engine Internals
- Performance Clutch
- Enhanced Cooling System
Upgraded Fuel Pump
To ensure adequate fuel delivery, an upgraded fuel pump is necessary. A high-flow fuel pump, such as the Walbro 255, can provide the necessary fuel volume to support your performance upgrades.
Stronger Engine Internals
If you’re aiming for the upper end of the horsepower spectrum, consider upgrading engine internals. Forged pistons and connecting rods can handle higher power levels and reduce the risk of engine failure.
Performance Clutch
A performance clutch is essential for transferring the increased power to the wheels. Upgrading to a heavy-duty clutch can prevent slippage and ensure that your Eclipse performs optimally under load.
Enhanced Cooling System
Improving the cooling system is vital for maintaining engine temperatures under high performance. Consider upgrading to a larger radiator, adding an oil cooler, or installing a more efficient thermostat.
Conclusion
Maximizing the performance of your Mitsubishi Eclipse GSX requires careful planning and the right upgrades. By investing in quality turbo components and supporting modifications, you can achieve impressive horsepower gains of 350-450 hp. Always remember to prioritize tuning and reliability to enjoy the full potential of your upgraded Eclipse.
