When it comes to high-performance builds, the choice of a turbocharger can significantly impact the engine’s efficiency and power output. The 13B rotary engine, known for its lightweight and compact design, has become a favorite among performance enthusiasts. In this article, we will explore the top single turbochargers suitable for 13B builds, focusing on the Garrett GT35R and the BorgWarner EFR 7670.
Understanding the 13B Rotary Engine
The 13B rotary engine, developed by Mazda, features a unique design that utilizes rotors instead of traditional pistons. This design allows for a higher power-to-weight ratio and smoother operation. However, to maximize its potential, many enthusiasts turn to turbocharging.
Why Choose a Single Turbocharger?
Single turbochargers offer several advantages for high-performance builds:
- Simplicity: A single turbo setup is generally easier to install and tune compared to twin-turbo systems.
