Top Upgrades for Ej255 Performance: Aps Intake, Turbo Back Exhaust, and Ecu Tuning

by

The Subaru EJ255 engine is a popular choice among enthusiasts looking to enhance their vehicle’s performance. With the right upgrades, you can significantly boost the power and efficiency of this engine. In this article, we will explore three of the top upgrades for EJ255 performance: the APS intake, turbo back exhaust, and ECU tuning.

1. APS Intake System

The APS intake system is designed to improve airflow to the engine, which can lead to better performance. By allowing more air to enter the engine, the APS intake can help increase horsepower and torque. Here are some key benefits:

  • Improved Airflow: The APS intake features a larger diameter and smoother bends, allowing for better airflow compared to the stock intake.
  • Increased Power: Many users report noticeable gains in horsepower and torque after installing the APS intake.
  • Enhanced Sound: The intake provides a more aggressive engine sound, adding to the overall driving experience.

Installation of the APS intake is straightforward, making it a great option for DIY enthusiasts. It is compatible with various EJ255 models, ensuring that most Subaru owners can benefit from this upgrade.

2. Turbo Back Exhaust System

A turbo back exhaust system is another essential upgrade for enhancing the performance of the EJ255 engine. This system replaces the entire exhaust path from the turbocharger to the rear of the vehicle. Here are the main advantages:

  • Reduced Back Pressure: A turbo back exhaust reduces back pressure, allowing the turbocharger to spool faster and more efficiently.
  • Increased Power Output: With improved exhaust flow, many drivers experience a significant increase in horsepower and torque.
  • Weight Savings: Aftermarket exhaust systems are often lighter than stock systems, contributing to better overall performance.

Choosing a quality turbo back exhaust system is crucial. Look for options that provide a balance between performance and sound, as some systems can be excessively loud.

3. ECU Tuning

ECU tuning is one of the most effective ways to maximize the performance of your EJ255 engine. By reprogramming the engine’s computer, you can optimize fuel delivery, ignition timing, and boost levels. Here are some benefits of ECU tuning:

  • Enhanced Performance: Proper tuning can unlock hidden power and improve throttle response.
  • Better Fuel Efficiency: A well-tuned engine can achieve better fuel economy, especially when combined with performance upgrades.
  • Custom Settings: Tuning allows for customization based on individual driving styles and preferences.

It’s essential to have ECU tuning performed by a professional or to use reputable tuning software. This ensures that the adjustments made are safe and effective for your specific setup.

Conclusion

Upgrading the EJ255 engine with an APS intake, turbo back exhaust, and ECU tuning can lead to significant improvements in performance. Each of these upgrades offers unique benefits that, when combined, can create a powerful and efficient engine setup. Whether you’re a seasoned enthusiast or a newcomer to the Subaru community, these upgrades are worth considering for enhancing your driving experience.
