Please read our FAQs page to find out more.

Stay sequential or go single turbo on the 13B‑REW?

Sequential twins offer smooth response but add vacuum/control complexity. Single turbos simplify plumbing and add headroom; choose A/R for response vs top‑end.

How do I keep response sharp with a larger turbo?

Use efficient intercooling, short/tight piping, and modern ball‑bearing CHRAs. A quality boost control strategy preserves midrange without surge.

What engine safeguards should I add at higher boost?

Knock/EGT monitoring, fuel pressure logging, conservative ignition, and proper premix strategy are critical to apex seal life and rotary reliability.
