Understanding the 13B Rotary Engine
The 13B rotary engine is a lightweight, compact powerplant that delivers impressive power-to-weight ratios. Its unique design allows for high RPMs and efficient power delivery, making it a popular choice for tuning and racing. However, to maximize its potential, selecting the right turbocharger is crucial.
Factors to Consider When Choosing a Turbocharger
- Size: The size of the turbocharger affects spool time and overall power output.
- Brand: Different brands offer varying reliability, performance, and support.
- Application: Consider whether the primary use is street driving, drag racing, or both.
- Boost Levels: Determine the desired boost levels for your performance goals.

Top 13B Single Turbo Options
1. Garrett GT2860R
The Garrett GT2860R is a popular choice among 13B enthusiasts due to its compact size and efficiency. This turbo is known for quick spool times and is ideal for both street and drag applications. With a maximum boost of around 20 PSI, it can support power levels up to 400 horsepower.
2. BorgWarner EFR 7670
The BorgWarner EFR 7670 turbocharger is renowned for its advanced engineering and performance. It features a twin-scroll design that enhances spool time and responsiveness. This turbo can produce around 500 horsepower, making it suitable for serious drag racing while still being street-friendly.
3. Precision Turbo PT6266
The Precision Turbo PT6266 is a high-performance option that offers exceptional power capabilities. With a maximum boost of 30 PSI, it can support over 700 horsepower, making it a favorite among drag racers. Its larger size may result in slightly slower spool times, but the power potential is undeniable.
Choosing the Right Size Turbo for Your Needs
When selecting a turbocharger for your 13B, size plays a critical role in performance. Smaller turbos tend to spool faster, providing quicker throttle response, which is ideal for street driving. Larger turbos, on the other hand, can produce more power but may have a lag in spool time, making them better suited for drag racing.
- Small Turbo (GT2860R): Best for street use with quick spool.
- Medium Turbo (EFR 7670): Balanced option for both street and drag.
- Large Turbo (PT6266): Best for maximum power in drag racing.
Brand Reliability and Support
Choosing a reputable brand is essential when investing in a turbocharger. Brands like Garrett, BorgWarner, and Precision Turbo are known for their quality and customer support. Researching reviews and user experiences can provide insight into reliability and performance.
Installation Considerations
Installing a turbocharger on your 13B can be a complex process. It’s essential to ensure that the turbo is compatible with your engine setup and that you have the necessary supporting modifications, such as upgraded fuel injectors, intercoolers, and exhaust systems. Professional installation is recommended for optimal results.
Conclusion
Choosing the right single turbo for your 13B engine involves careful consideration of size, brand, and application. By understanding the characteristics of different turbochargers and how they align with your performance goals, you can make an informed decision that enhances your driving experience, whether on the street or the drag strip.
