The Mazda 13B-REW rotary engine is renowned for its lightweight design and high-revving capabilities. For enthusiasts looking to maximize power output in the range of 350 to 400 horsepower, selecting the right turbo upgrades is crucial. This article explores the top turbo upgrades that can help you unleash the full potential of your 13B-REW engine.
Understanding the 13B-REW Engine
The 13B-REW engine, part of Mazda’s Wankel rotary engine family, features a compact design and unique rotary combustion process. This engine is capable of producing significant power relative to its size, making it a favorite among car enthusiasts. However, to achieve higher horsepower levels, modifications are often necessary.
Key Turbo Upgrades for 350-400 HP
1. Larger Turbocharger
Upgrading to a larger turbocharger can provide the airflow needed to increase horsepower. Consider these options:
- Garrett GT28 – A popular choice for its balance of spool time and power.
- Precision 6266 – Known for its high power potential and efficiency.
2. High-Flow Fuel Injectors
To support increased power levels, upgrading fuel injectors is essential. Look for injectors that can handle the increased fuel demand:
- RX-8 Injectors – These provide a good balance of flow and compatibility.
- RC Engineering Injectors – Custom options available for specific power goals.
3. Upgraded Intercooler
An upgraded intercooler helps maintain optimal intake temperatures, which is critical for performance. Consider these options:
- FMIC (Front Mount Intercooler) – Offers better cooling efficiency.
- V-Mount Intercooler – Provides a compact solution with excellent airflow.
4. Performance Exhaust System
A high-performance exhaust system reduces back pressure and enhances engine efficiency. Key components include:
- Cat-Back Exhaust – Improves exhaust flow and sound.
- High-Flow Catalytic Converter – Reduces restrictions while remaining street-legal.
5. ECU Tuning
After upgrading hardware components, ECU tuning is necessary to optimize performance. Options include:
- Standalone ECU – Offers full control over engine parameters.
- Reflash Tuning – Adjusts stock ECU settings for better performance.
Installation Tips
When installing turbo upgrades, consider the following tips to ensure optimal performance:
- Follow manufacturer instructions carefully.
- Use high-quality gaskets and seals to prevent leaks.
- Consider professional installation if you are unsure about the process.
Conclusion
Maximizing the power of the Mazda 13B-REW engine requires careful selection of turbo upgrades and supporting modifications. By choosing the right components and ensuring proper installation, you can achieve impressive horsepower levels in the 350 to 400 HP range. Always remember to tune your engine accordingly to make the most of these upgrades.
