The Mitsubishi Lancer Evolution IX, commonly known as the Evo 9, is a high-performance vehicle that has captured the hearts of car enthusiasts around the world. Upgrading the turbocharger is one of the most effective ways to enhance the performance of your Evo 9. In this article, we will explore the best practices for upgrading the turbos on your Evo 9, focusing on brands, sizes, and boost levels.
Understanding Turbochargers
A turbocharger is a device that uses exhaust gases to spin a turbine, which in turn compresses the intake air, allowing for more air to enter the engine. This process increases horsepower and torque, making it a popular modification for performance vehicles like the Evo 9. Before upgrading, it’s essential to understand the different components and their functions.
- Compressor Wheel: Increases air flow into the engine.
- Turbine Wheel: Converts exhaust energy into mechanical energy.
- Wastegate: Controls boost pressure by diverting exhaust flow.
Choosing the Right Turbo Brand
When it comes to upgrading the turbo on your Evo 9, selecting a reputable brand is crucial. Here are some of the most trusted brands in the market:
- Garrett: Known for its high-quality turbochargers, Garrett offers a range of options suitable for the Evo 9.
- HKS: A popular choice among enthusiasts, HKS turbos provide excellent performance and reliability.
- FP (Forced Performance): Specializes in high-performance turbos specifically designed for the Evo series.
- Blouch: Offers a variety of turbo upgrades that are known for their efficiency and power.
Turbo Sizes and Their Impact
The size of the turbocharger significantly affects the performance characteristics of your Evo 9. Here are some common sizes and their implications:
- Small Turbos (e.g., 16G): Quick spool time, ideal for street use, but may limit high-end power.
- Medium Turbos (e.g., 20G): Balanced performance, suitable for both street and track applications.
- Large Turbos (e.g., 35R): High power potential, but may have lag, making them better for racing.
Boost Levels and Tuning
Boost levels refer to the amount of pressure the turbocharger generates. Proper tuning is essential to maximize performance while maintaining engine reliability. Here’s what you need to know:
- Stock Boost: Typically around 18-20 PSI; suitable for daily driving.
- Moderate Boost: 22-25 PSI; requires upgraded fuel system and tuning for safety.
- High Boost: 26 PSI and above; necessitates extensive modifications and careful tuning.
Supporting Modifications
Upgrading the turbo on your Evo 9 often requires additional modifications to support the increased power. Consider the following:
- Fuel System: Upgraded injectors and fuel pump are necessary for higher boost levels.
- Exhaust System: A high-flow exhaust will help reduce back pressure and improve turbo efficiency.
- Intercooler: A larger intercooler can help manage intake temperatures, enhancing performance.
- Tuning: Professional tuning is critical to ensure the engine runs safely and efficiently.
Installation Tips
Proper installation of your new turbocharger is vital for optimal performance. Here are some tips to consider:
- Follow Manufacturer Instructions: Always adhere to the specific guidelines provided by the turbo manufacturer.
- Use Quality Gaskets: Ensure all gaskets are new and of high quality to prevent leaks.
- Check for Clearances: Ensure there is adequate space for the turbo and that it does not interfere with other components.
- Double-Check Connections: Verify all connections are secure to avoid boost leaks.
Conclusion
Upgrading the turbo on your Evo 9 can dramatically improve its performance. By selecting the right brand, size, and boost level, along with supporting modifications and proper installation, you can maximize the potential of your vehicle. Always remember to tune your car appropriately to ensure reliability and performance. Happy tuning!
