The Subaru WRX has long been a favorite among car enthusiasts, particularly those who enjoy tuning and modifying their vehicles for enhanced performance. One of the key components that can significantly boost horsepower is the engine’s pistons. In this article, we will explore how forged pistons from JE and Wiseco can add over 50 horsepower to your turbocharged Subaru WRX.
Understanding Forged Pistons
Forged pistons are engineered from a solid piece of metal, making them stronger and more durable than their cast counterparts. This strength allows them to withstand the extreme pressures and temperatures generated by turbocharged engines. Let’s delve deeper into the benefits of using forged pistons in your WRX.
- Increased Strength: Forged pistons can handle higher boost levels without failure.
- Improved Performance: They allow for better compression ratios, enhancing overall engine efficiency.
- Weight Reduction: Many forged pistons are lighter, contributing to improved throttle response.
