Achieving 550 Hp with a 4g63 Turbo: Recommended Piping, Injectors, and Boost Control

by

Achieving 550 horsepower with a 4G63 turbo engine is a challenging yet rewarding endeavor for automotive enthusiasts. This article will cover essential components such as piping, injectors, and boost control that are crucial for reaching this power level.

Understanding the 4G63 Turbo Engine

The 4G63 turbo engine, originally developed by Mitsubishi, is known for its robust design and tuning potential. It has been used in various models, particularly the Mitsubishi Eclipse and Lancer Evolution. With the right modifications, this engine can produce impressive horsepower figures.

Proper piping is essential for optimizing airflow and reducing turbo lag. Here are some recommendations:

  • Intercooler Piping: Use 3-inch aluminum piping to minimize restrictions and improve airflow.
  • Turbo Inlet Piping: A larger inlet pipe (around 3 inches) helps to ensure that the turbocharger receives enough air.
  • Exhaust Piping: A 3-inch turbo-back exhaust system is recommended to reduce back pressure and enhance exhaust flow.

Choosing the Right Injectors

Fuel injectors play a vital role in delivering the correct amount of fuel to achieve high horsepower. For 550 HP, consider the following:

  • Injector Size: Aim for 1000cc or larger fuel injectors to ensure adequate fuel delivery.
  • Injector Type: High-impedance injectors are preferred for better compatibility with stock ECU systems.
  • Brand Recommendations: Brands like DeatschWerks, Injector Dynamics, and Fuel Injector Clinic are known for reliability and performance.

Boost Control Strategies

Controlling boost pressure is crucial for achieving and maintaining 550 HP. Here are effective strategies:

  • Boost Controller Type: Use an electronic boost controller for precise control over boost levels.
  • Wastegate Setup: A 38mm or larger external wastegate can help manage boost pressure more effectively.
  • Boost Levels: Aim for a boost level of 25-30 PSI, depending on your specific setup and fuel quality.

Supporting Modifications

To support the increased power levels, additional modifications may be necessary:

  • Upgraded Fuel Pump: A high-flow fuel pump is essential to keep up with the fuel demands of larger injectors.
  • Engine Management: Consider an aftermarket ECU or tuning solution to optimize fuel maps and ignition timing.
  • Stronger Internals: Upgrading to forged pistons and connecting rods can help handle the increased power safely.

Conclusion

Achieving 550 HP with a 4G63 turbo engine requires careful planning and the right components. By focusing on piping, injectors, and boost control, along with supporting modifications, you can unlock the full potential of this legendary engine.
