The Subaru WRX GD generation has gained a reputation for being a tuner’s dream, especially for those looking to enhance performance. With the right modifications, achieving over 350 horsepower is not only possible but also quite achievable. In this article, we will explore the top power mods for the GD WRX, focusing on the Cobb Stage 2 package and other essential upgrades.
Understanding the Cobb Stage 2 Package
The Cobb Stage 2 package is one of the most popular tuning options for the GD WRX. This package includes a variety of components designed to optimize your vehicle’s performance, including a high-flow downpipe and an access port for tuning.
- High-Flow Downpipe: This component replaces the factory downpipe, allowing for better exhaust flow and reduced turbo lag.
- Accessport Tuner: The Accessport allows for easy tuning adjustments and provides real-time feedback on engine performance.
Essential Upgrades for Achieving 350+ HP
While the Cobb Stage 2 package provides a solid foundation, there are several additional upgrades that can help you reach and exceed the 350 horsepower mark.
1. Upgraded Turbocharger
Replacing the stock turbocharger with a larger, more efficient unit can significantly increase horsepower. Options such as the Garrett GTX series or the Blouch Dominator turbochargers are popular choices among enthusiasts.
2. Intercooler Upgrade
An upgraded intercooler can help manage intake temperatures, allowing for more consistent power delivery. Look for options like the Mishimoto or Process West intercoolers, which provide excellent cooling efficiency.
3. Fuel System Upgrades
To support higher horsepower levels, upgrading the fuel system is essential. This includes larger fuel injectors and a high-flow fuel pump to ensure your engine receives the necessary fuel for optimal performance.
- Fuel Injectors: Consider 850cc or larger injectors for adequate fuel delivery.
- Fuel Pump: An upgraded fuel pump will prevent fuel starvation during high-demand situations.
4. Exhaust System Upgrade
A free-flowing exhaust system can help reduce back pressure and improve overall performance. Consider a cat-back exhaust system from brands like Invidia or Borla for enhanced sound and performance.
5. Engine Management Tuning
After making significant upgrades, a professional tune is crucial to ensure your engine runs efficiently and safely. A custom tune can optimize fuel maps and ignition timing for the best performance.
Conclusion
Achieving over 350 horsepower in a GD WRX is an exciting goal for many enthusiasts. By starting with the Cobb Stage 2 package and incorporating essential upgrades like a larger turbocharger, upgraded intercooler, and enhanced fuel system, you can unlock the full potential of your WRX. Remember to invest in proper tuning to maximize performance and ensure reliability.
