The performance of the 13B rotary engine has always attracted enthusiasts and tuners alike. With the right turbo upgrades, these engines can reach impressive power levels. In this article, we will compare the dyno results of turbo upgrades from two leading manufacturers, BorgWarner and Garrett, to see which offers the best performance for the 13B engine.
Understanding the 13B Rotary Engine
The 13B rotary engine, known for its compact size and lightweight design, has been a favorite among tuners. Its unique rotary design allows for high RPMs and a smooth power delivery. However, to maximize its potential, many enthusiasts turn to turbocharging.
Turbochargers Overview
Turbochargers increase an engine’s efficiency and power output by forcing more air into the combustion chamber. Both BorgWarner and Garrett offer a range of turbochargers suitable for the 13B engine. Below, we will look at the specifications and features of each brand’s offerings.
BorgWarner Turbochargers
BorgWarner is known for its innovative turbocharger designs. Their turbos often feature advanced technologies that improve spool time and overall efficiency. Key models for the 13B include:
