The Mazda RX-7, particularly the 13B-REW variant, is a legendary sports car known for its lightweight design and rotary engine performance. For enthusiasts looking to enhance their driving experience, boosting the power output to 400+ horsepower is an achievable goal. Here, we present the top five power gains that can elevate your RX-7’s performance to new heights.
1. Upgraded Turbocharger
One of the most significant upgrades you can make to your RX-7 is installing a high-performance turbocharger. This component is crucial for increasing the engine’s air intake, leading to higher power outputs.
- Choose a turbocharger that matches your power goals.
- Consider options like the Garrett GT series for reliability and performance.
2. High-Performance Intercooler
An upgraded intercooler helps reduce the temperature of the compressed air coming from the turbocharger. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which results in increased horsepower.
- Look for front-mounted intercoolers for optimal cooling efficiency.
- Ensure proper fitment to avoid any airflow restrictions.
3. Engine Management System (EMS)
Upgrading the engine management system is essential for tuning your RX-7 to handle increased power. A standalone EMS allows for precise adjustments to fuel maps, ignition timing, and boost levels.
- Consider systems like the AEM or Haltech for advanced tuning capabilities.
- Professional tuning is recommended to maximize performance and reliability.
4. Exhaust System Upgrade
A high-flow exhaust system reduces back pressure, allowing the engine to expel exhaust gases more efficiently. This upgrade can significantly enhance throttle response and overall power output.
- Look for cat-back exhaust systems that provide a balance between sound and performance.
- Consider removing the catalytic converter for racing applications, but be mindful of emissions regulations.
5. Lightweight Flywheel
Installing a lightweight flywheel reduces rotational mass, allowing the engine to rev more freely. This upgrade improves acceleration and responsiveness, making your RX-7 feel more agile on the road or track.
- Choose a flywheel that is designed specifically for the 13B-REW engine.
- Pair with a performance clutch for optimal power transfer.
By implementing these five power gains, you can unlock the full potential of your Mazda RX-7 13B-REW, pushing the horsepower to over 400. Each upgrade complements the others, resulting in a well-rounded and thrilling driving experience.
