The 2004 Subaru WRX STI represents a pinnacle of driver-focused engineering, combining raw turbocharged power with a chassis tuned for precision. This specific model year solidified the legacy of the Impreza-based performance machine, offering a blend of accessibility and capability that remains compelling to enthusiasts today. Understanding the 2004 WRX STI specs is essential for appreciating its role in automotive history and its continued relevance in the used performance market.
Engine and Performance Specifications
At the heart of the 2004 WRX STI lies the horizontally-opposed, turbocharged Subaru boxer engine. This configuration provides a low center of gravity, enhancing handling dynamics that feel remarkably responsive and stable. The mechanical precision and engineering behind this powertrain are evident in every aspect of the vehicle's performance, making it a benchmark in its class.
Engine Details and Output
The core powerplant is a 2.0-liter, horizontally-opposed four-cylinder, known internally as the EJ207. This engine is specifically designed for the STI variant, featuring forged components to withstand the significant stress of turbocharging. The result is a robust and high-revving power unit that delivers an engaging driving experience.
Engine Type: Subaru EJ207 2.0L Horizontally-Opposed (Boxer)
Configuration: Turbocharged, Intercooled, DOHC, 4 valves per cylinder
Power Output: 300 horsepower @ 6,000 rpm
