Best Upgrades for Mitsubishi Evo Ix: from 300 Hp to 400+ Hp

by

The Mitsubishi Evo IX is a beloved vehicle among car enthusiasts, known for its impressive performance and tuning potential. With a stock output of around 300 horsepower, many owners seek upgrades to push their Evo IX beyond 400 horsepower. In this article, we will explore the best upgrades to achieve this goal while maintaining reliability and drivability.

Engine Upgrades

To increase horsepower significantly, upgrading engine components is essential. Here are some of the best engine upgrades for the Evo IX:

  • Aftermarket Turbocharger: Upgrading to a larger turbocharger can provide a substantial increase in horsepower. Options like the FP Black or the Garrett GTX3071R are popular choices.
  • High-Performance Intercooler: A larger intercooler helps to reduce intake temperatures, improving performance and efficiency. Look for brands like ETS or Mishimoto.
  • Upgraded Fuel Injectors: To support higher horsepower, larger fuel injectors are necessary. Consider 1000cc injectors for optimal performance.
  • High-Performance Fuel Pump: An upgraded fuel pump, such as the Walbro 255, ensures that your engine receives the necessary fuel supply for increased power.
  • ECU Tune: A proper ECU tune is crucial after any major upgrades. This optimizes fuel maps and boosts performance. Companies like EcuTek or Cobb Tuning offer excellent tuning solutions.

Exhaust System Upgrades

Upgrading the exhaust system can significantly improve airflow, which is vital for performance. Here are some recommended upgrades:

  • High-Performance Downpipe: Replacing the stock downpipe with a high-flow version reduces back pressure and increases turbo spool time.
  • Cat-Back Exhaust System: A cat-back exhaust system enhances exhaust flow and provides a more aggressive sound. Brands like HKS and Invidia are popular choices.
  • Test Pipe: Replacing the catalytic converter with a test pipe can further reduce restrictions, but be aware of local emissions regulations.

Suspension and Handling Upgrades

With increased power, handling upgrades become essential to maintain control and performance. Consider the following:

  • Coilover Suspension: Upgrading to a coilover suspension system allows for adjustable ride height and improved handling characteristics.
  • Strut Tower Brace: A strut tower brace enhances chassis stiffness, improving handling and cornering stability.
  • Upgraded Sway Bars: Stiffer sway bars reduce body roll during cornering, providing better grip and control.

Braking System Upgrades

As you increase horsepower, upgrading the braking system is critical for safety and performance. Here are some effective upgrades:

  • Performance Brake Pads: Upgrading to high-performance brake pads improves stopping power and reduces fade during aggressive driving.
  • Slotted or Drilled Rotors: These rotors enhance cooling and improve braking performance, especially during track days.
  • Stainless Steel Brake Lines: These lines provide a firmer brake pedal feel and reduce expansion under pressure.

Wheels and Tires

Upgrading wheels and tires is essential for maximizing grip and performance. Here are some recommendations:

  • Lightweight Wheels: Switching to lightweight forged wheels reduces unsprung weight, improving acceleration and handling.
  • Performance Tires: High-performance tires, such as Michelin Pilot Sport or Bridgestone Potenza, provide better grip and stability.

Conclusion

Upgrading a Mitsubishi Evo IX from 300 horsepower to over 400 horsepower is an exciting journey that involves various enhancements. By focusing on engine, exhaust, suspension, braking, and wheel upgrades, you can achieve a well-rounded performance vehicle that delivers thrilling driving experiences. Always remember to balance power with safety and reliability for the best results.
