The 2004 Mazdaspeed Miata represents the pinnacle of the second-generation NA platform, merging the roadster’s legendary handling with turbocharged performance. Offered exclusively as a coupe, this model year delivered a refined and potent driving experience that remains highly sought after by enthusiasts today. Understanding the precise specifications of this car is essential for appreciating its engineering and for anyone considering purchase or restoration.
Engine and Performance Specifications
The Turbocharged Heart of the Car
At the core of the 2004 Mazdaspeed Miata lies a significantly upgraded powertrain that distinguishes it from the standard NA models. The engine is a 1.8-liter inline-four, designated as the MZR-R, which incorporates a Garrett T28 turbocharger. This setup generates a respectable 178 horsepower and 182 lb-ft of torque, a substantial increase over the naturally aspirated variant. This specific engine configuration was a collaborative effort between Ford and Mazda, designed to deliver a linear power band and engaging response rather than brute force.
Drivetrain and Suspension Enhancements
Power is transmitted to the rear wheels through a close-ratio 5-speed manual transmission, optimized for the turbocharged output. The chassis received significant reinforcement and tuning to manage the added power. Key upgrades include Mazdaspeed-specific struts and shocks, a front anti-roll bar, and a rear stabilizer bar. These components work in concert to reduce body roll and improve high-speed stability, ensuring the car remains planted and predictable during spirited driving.
Exterior and Interior Design Details
Distinctive Styling Cues
The 2004 model year is visually identified by its aggressive front fascia, which houses a larger grille and integrated fog lights. The iconic round headlights are framed by smoked housings, contributing to the car's aggressive stance. Side skirts and a rear diffuser complement the look, while the signature red "Mazdaspeed" emblem on the rear decklid confirms its performance credentials.
Refined Interior Components
Inside, the cabin is a blend of sport and luxury. Recaro front bucket seats provide excellent lateral support for the driver and passenger, upholstered in perforated leather. The steering wheel is a three-spale design, wrapped in leather and equipped with audio and cruise controls for convenience. A leather-wrapped shift knob completes the premium feel, making long drives comfortable while maintaining a direct connection to the road.
