The Mazda 13B rotary engine is renowned for its lightweight design and high-revving capabilities. When it comes to turbocharging the 13B, selecting the right wastegate is crucial for maximizing power gains. In this article, we will explore the best wastegate options available for 13B turbo upgrades, ensuring you can achieve optimal performance.
Understanding Wastegates
A wastegate is a critical component of a turbocharged engine that regulates the boost pressure produced by the turbocharger. It controls the flow of exhaust gases to the turbine, ensuring that the turbocharger does not produce excessive boost, which can lead to engine damage. There are two main types of wastegates: internal and external.
Types of Wastegates
- Internal Wastegates: Built into the turbocharger, these are compact and easier to install. They are suitable for lower power applications.
- External Wastegates: Mounted separately from the turbo, these offer better boost control and are ideal for high-performance setups.
