Upgrading to the IS38 turbocharger on the EA888 Gen 3 engine is a popular modification among enthusiasts looking to enhance performance. This article will explore the necessary supporting modifications and the expected results of such an upgrade.

Understanding the IS38 Turbocharger

The IS38 turbocharger is a direct upgrade from the stock turbo found on the EA888 Gen 3 engine. It provides increased airflow and efficiency, leading to significant power gains. The IS38 is designed to work seamlessly with the engine’s existing components, but to maximize its potential, supporting modifications are essential.

Necessary Supporting Mods

  • Upgraded Intercooler: A larger intercooler is vital for reducing intake temperatures, which helps maintain performance and reliability.
  • High-Flow Intake System: An upgraded intake system improves airflow to the turbocharger, allowing it to spool faster and produce more power.
  • Performance Exhaust System: A less restrictive exhaust system enhances turbo efficiency by reducing back pressure.
  • Upgraded Fuel Pump: The stock fuel pump may struggle to keep up with the increased demand for fuel, so a high-pressure fuel pump is recommended.
  • ECU Tune: A proper tune is essential to optimize the engine’s performance and ensure safe operation with the new turbo.

Expected Results

After upgrading to the IS38 and implementing the necessary supporting mods, enthusiasts can expect substantial performance improvements. Here are some anticipated results:

  • Increased Horsepower: Power gains of 50-100 horsepower are common, depending on supporting mods and tuning.
  • Improved Torque: Torque delivery is enhanced, resulting in better acceleration and throttle response.
  • Better Throttle Response: The upgraded turbo allows for quicker spool times, leading to a more responsive driving experience.
  • Enhanced Engine Sound: A performance exhaust system can provide a more aggressive sound, enhancing the overall driving experience.
  • Higher Boost Levels: The IS38 can handle higher boost levels, allowing for more power potential with further tuning.

Conclusion

Upgrading to the IS38 turbocharger on the EA888 Gen 3 engine is a rewarding modification that can significantly enhance performance. By ensuring that you have the necessary supporting mods and a proper tune, you can unlock the full potential of your vehicle. Always consult with a professional tuner to achieve the best results and maintain reliability.
