When it comes to maximizing the performance of a 13B rotary engine, selecting the appropriate single turbocharger is crucial, especially for those aiming for 700+ horsepower. This guide will help you navigate through the various brands and sizes available in the market.
Understanding the 13B Rotary Engine
The 13B rotary engine, known for its lightweight and compact design, has gained popularity among car enthusiasts and tuners. Achieving high horsepower figures requires careful consideration of turbocharger specifications to ensure optimal performance and reliability.
Key Factors in Choosing a Turbocharger
- Size: The turbo size affects airflow and boost levels.
- Brand Reputation: Established brands often provide better reliability and support.
- Compressor and Turbine Design: Different designs offer varying performance characteristics.
- Boost Threshold: It’s important to consider when the turbo will start producing boost.
Turbocharger Sizing
Choosing the right size turbocharger is essential for achieving the desired horsepower. A turbo that is too small will limit power, while one that is too large may lead to lag and poor drivability.
- Small Turbo (T3/T4): Suitable for quick spool and lower RPM power, typically up to 600 HP.
- Medium Turbo (GT30/GT35): A balance of spool time and power, ideal for 600-800 HP.
- Large Turbo (GT40): Best for maximum horsepower, but may have significant lag, suitable for 800+ HP.
