The 13B-REW engine, a hallmark of rotary performance, has captured the hearts of enthusiasts and tuners alike. Achieving 350 horsepower from this compact powerhouse can be a cost-effective venture when approached with the right knowledge and resources. This article will explore expert build guides from reputable shops, providing insights into the modifications and upgrades necessary to reach this performance milestone.
Understanding the 13B-REW Engine
The 13B-REW is a 1.3-liter rotary engine produced by Mazda, known for its lightweight design and high-revving capabilities. With its unique rotary design, tuning options are plentiful, allowing for significant power gains with the right modifications.
Key Components for a 350 HP Build
- Upgraded Turbocharger
- High-Performance Fuel Injectors
- Custom Engine Management System
- Aftermarket Exhaust System
- Improved Intercooler
1. Upgraded Turbocharger
One of the most effective ways to increase horsepower is by upgrading the turbocharger. A larger turbo can provide the necessary boost to achieve 350 hp without sacrificing reliability. Consider options like the Garrett GT28 or a BorgWarner turbo for optimal performance.
2. High-Performance Fuel Injectors
To support increased power, high-performance fuel injectors are essential. Upgrading to injectors capable of delivering more fuel will ensure that the engine receives the necessary amount of fuel for combustion, particularly at higher boost levels.
3. Custom Engine Management System
A custom engine management system allows for precise tuning of the engine’s fuel and ignition maps. This is crucial for maximizing performance and ensuring reliability. Options like the AEM Infinity or Haltech Elite are popular among tuners.
4. Aftermarket Exhaust System
An aftermarket exhaust system can enhance airflow, reduce back pressure, and improve the overall sound of the vehicle. Brands like HKS and Greddy offer systems specifically designed for the 13B-REW that can help achieve the desired power levels.
5. Improved Intercooler
Upgrading the intercooler is vital for maintaining optimal air temperatures, especially when running higher boost levels. A larger, more efficient intercooler from companies like Mishimoto or PWR can significantly improve performance and reliability.
