This article explores how much power you can expect from an IHI VF52 turbo upgrade and what it entails.

Understanding the IHI VF52 Turbocharger

The IHI VF52 turbocharger is a factory upgrade for the Subaru WRX, particularly in the 2008-2014 models. It is designed to provide improved airflow and increased boost pressure compared to the stock turbocharger. This results in significant power gains when paired with appropriate engine management and supporting modifications.

Power Gains from the IHI VF52 Upgrade

When upgrading to the IHI VF52 turbo, power gains can vary based on several factors including engine condition, supporting modifications, and tuning. However, on average, you can expect the following power increases:

  • Stock WRX power: Approximately 265 horsepower
  • With IHI VF52 turbo: Up to 320-350 horsepower

Factors Influencing Power Output

Several factors can influence the final power output after installing the IHI VF52 turbo. These include:

  • Engine Tuning: Proper tuning is crucial to maximize the potential of the turbo upgrade.
  • Supporting Mods: Upgrades such as intercoolers, exhaust systems, and intake systems can significantly impact performance.
  • Fuel Quality: Using high-octane fuel can help achieve better performance and prevent knocking.
  • Engine Health: A well-maintained engine will perform better than one that has not been cared for.

To fully benefit from the IHI VF52 turbo upgrade, consider the following supporting modifications:

  • Aftermarket Intercooler: Helps maintain lower intake temperatures.
  • High-Performance Exhaust System: Improves exhaust flow and reduces back pressure.
  • Upgraded Fuel Injectors: Ensures adequate fuel delivery for increased power levels.
  • ECU Tune: Adjusts engine parameters for optimal performance with the new turbo.

Installation Considerations

Installing the IHI VF52 turbocharger requires mechanical knowledge and experience. Here are some considerations:

  • Necessary Tools: Ensure you have the right tools for the job, including wrenches, sockets, and possibly a lift.
  • Time Commitment: Installation can take several hours, so plan accordingly.

Conclusion

The IHI VF52 turbo upgrade can significantly enhance the performance of your Subaru WRX, potentially adding 55-85 horsepower. However, to achieve these gains, it is essential to consider supporting modifications and proper tuning. With the right approach, the VF52 can transform your WRX into a more powerful and exhilarating driving machine.
