The Subaru WRX has long been a favorite among car enthusiasts, particularly for those interested in tuning and performance upgrades. One popular build is the 350 horsepower (HP) flex fuel setup, which allows for greater power output and flexibility in fuel choice. In this article, we will break down the costs associated with achieving a 350 HP WRX flex fuel build, including parts, tuning, and installation.
Understanding Flex Fuel Systems
Flex fuel systems enable vehicles to run on different fuel blends, typically gasoline and ethanol. This flexibility can lead to increased power and efficiency when tuned correctly. For a WRX, this means optimizing the engine to handle higher ethanol content, which can provide more horsepower.
