What are the benefits of upgrading your turbo and intercooler on a 2019-2022 WRX STI?

Upgrading your turbocharger and intercooler can significantly improve your WRX STI’s power delivery and efficiency. A high-performance turbo provides quicker spool times and increased boost capacity, while an upgraded intercooler reduces intake air temperatures, helping to maintain consistent power under demanding conditions. Together, these upgrades enhance throttle response and engine reliability during spirited driving.

  • Faster turbo spool for improved acceleration
  • Lower intake temperatures for sustained power
  • Reduced turbo lag and improved throttle response
  • Better heat management during extended use

How do I choose the right forced induction components for my power goals?

Selecting the right turbo, intercooler, and supporting parts depends on your desired power level, driving style, and intended use. For moderate power increases, a direct-fit turbo upgrade paired with a high-flow intercooler is ideal. For more aggressive builds, consider larger turbos and upgraded charge pipes to handle increased airflow. Always factor in tuning and supporting modifications to ensure reliability and drivability.

What supporting modifications should I consider with forced induction upgrades?

To fully realize the benefits of your forced induction upgrades, supporting modifications and proper tuning are essential. Upgraded fuel injectors, high-flow intake systems, and enhanced engine management help maintain safe air-fuel ratios and optimize performance. Additionally, boost controllers and blow-off valves improve boost stability and throttle response. Explore our full range of forced induction parts at Subimods to complete your WRX STI build.
