The automotive world is filled with stories of performance and engineering excellence, but few are as compelling as the tale of the 13B-REW engine. This rotary powerhouse has captured the hearts of car enthusiasts and tuners alike, especially when it comes to the iconic Mazda FC3S. In this article, we will explore how a well-built 13B-REW engine can achieve an impressive 350 wheel horsepower (WHP) while still being street-friendly.
The 13B-REW Engine: A Brief Overview
The 13B-REW is a lightweight, compact rotary engine that is known for its high-revving capabilities and unique design. Developed by Mazda, this engine features a two-rotor layout that allows for a smooth power delivery and an exhilarating driving experience. Its architecture provides a strong foundation for tuning and performance upgrades.
Building the 13B-REW for Performance
To achieve 350 WHP, a number of modifications and enhancements are necessary. Below are key components that contribute to a successful build:
- Upgraded Turbocharger: A larger turbocharger allows for increased airflow and boost pressure, essential for higher power outputs.
- Aftermarket Fuel Injectors: High-flow injectors ensure that the engine receives enough fuel to support the increased air intake.
- Performance Exhaust System: A free-flowing exhaust reduces back pressure and enhances turbo efficiency.
- ECU Tuning: Proper tuning of the engine control unit maximizes performance by optimizing fuel maps and ignition timing.
- Upgraded Intercooler: A larger intercooler helps to reduce intake temperatures, improving overall efficiency and power.
Real-world Performance: The FC3S Experience
The FC3S, or Mazda RX-7, is a lightweight sports car that perfectly complements the 13B-REW engine. With a well-executed build, drivers can experience thrilling performance on the street without sacrificing drivability. Here are some real-world results and driving impressions:
- Acceleration: The FC3S with a 350 WHP 13B-REW can achieve 0-60 mph in approximately 4 seconds, providing a thrilling launch.
- Handling: The lightweight chassis and balanced weight distribution allow for precise cornering and agile handling.
- Daily Driveability: With proper tuning, the engine remains reliable and responsive, making it suitable for everyday use.
