The Subaru WRX and Mitsubishi Lancer Evolution (Evo) are two of the most iconic performance cars in the automotive world. Both vehicles have a loyal following and are often pitted against each other in discussions about tuning and performance upgrades. One of the most effective ways to increase horsepower in these cars is through turbo upgrades. This article will explore the best turbo upgrades for the WRX and Evo, focusing on how to reach 500+ horsepower while maintaining stock internals.
Understanding Turbochargers
Before diving into specific turbo upgrades, it’s essential to understand how turbochargers work. A turbocharger compresses the air entering the engine, allowing for more air and fuel to be burned, which increases power output. The efficiency of a turbocharger can significantly impact performance, especially when aiming for high horsepower numbers.
Best Turbo Upgrades for WRX
The Subaru WRX has a rich tuning culture, and several turbo options can help enthusiasts reach their horsepower goals. Here are some of the best turbo upgrades for the WRX:
- Garrett GTX3071R – This turbo is known for its quick spool and excellent power delivery, making it a popular choice for WRX owners looking to hit the 500 hp mark.
- Blouch 1.5XTR – With a larger compressor wheel, this turbo provides a significant increase in power and efficiency, ideal for those wanting to maximize their WRX’s potential.
- FP Green – A well-balanced turbo that offers great performance without sacrificing daily drivability, making it a favorite among WRX enthusiasts.
- Precision 5858 – Known for its high flow capabilities, this turbo can support well over 500 hp and is a solid choice for serious tuners.
Best Turbo Upgrades for Evo
The Mitsubishi Evo also has a strong aftermarket support system, with numerous turbo options available. Here are some of the best turbo upgrades for the Evo:
- Garrett GTX3076R – This turbo offers a fantastic balance of spool time and peak power, making it a top choice for Evo enthusiasts targeting 500 hp.
- FP Red – Known for its ability to produce high horsepower numbers, the FP Red is a popular option for those looking to push their Evo to the limits.
- Blouch 2.5XTR – This turbo is designed for maximum flow and power, making it suitable for serious performance builds aiming for over 500 hp.
- Precision 6266 – A high-performance turbo that can easily support 500 hp and beyond, it’s a great option for Evo owners looking for serious upgrades.
Comparing WRX and Evo Turbo Upgrades
When comparing turbo upgrades for the WRX and Evo, several factors come into play:
- Spool Time: The time it takes for the turbo to reach full boost can affect drivability. The WRX turbos tend to spool quicker, while some Evo turbos may take longer but offer higher peak power.
- Power Band: Different turbos provide varying power bands. WRX turbos often deliver power in a more linear fashion, while Evo turbos may provide a more aggressive power curve.
- Cost: Pricing can vary significantly between turbo options. It’s essential to consider the overall cost of the turbo, supporting modifications, and installation.
- Reliability: Both platforms can handle high horsepower with stock internals, but proper tuning and supporting modifications are crucial for reliability.
Supporting Modifications
To safely reach 500+ hp on stock internals, several supporting modifications are recommended for both the WRX and Evo:
- Upgraded Fuel System: A high-flow fuel pump and larger injectors are necessary to meet the increased fuel demands.
- ECU Tuning: Custom tuning is essential to optimize performance and ensure the engine runs safely with the new turbo setup.
- Intercooler Upgrade: A larger intercooler helps reduce intake temperatures, improving performance and reliability.
- Exhaust System: A high-flow exhaust system reduces back pressure, allowing the turbo to spool more efficiently and produce more power.
Conclusion
Both the Subaru WRX and Mitsubishi Lancer Evolution have impressive potential for reaching 500+ horsepower with the right turbo upgrades. By carefully selecting a turbo and implementing necessary supporting modifications, enthusiasts can enjoy the thrill of high-performance driving while maintaining the reliability of stock internals. Whether you choose the WRX or Evo, the journey to 500 hp is an exciting one filled with possibilities.
