2200cc Bosch EV14 Fuel Injectors for Mazda Rotary 20B 3‑Rotor – High‑Impedance | SouthBay Fuel Injectors

The SouthBay Fuel Injectors 2200cc Mazda Rotary 20B 3‑Rotor Upgrade provides the fuel volume, precision, and reliability required for high‑output rotary engines. Built using genuine high‑impedance Bosch EV14 cores rated at 43.5 psi (3 Bar) , these injectors deliver exceptional linearity, fast response, and excellent atomization across the entire pulse range.

Each injector set is dynamically flow‑matched to within ±1% for consistent cylinder‑to‑cylinder fueling accuracy . The combination of precise matching and EV14 response characteristics produces remarkably smooth idle quality, even at large flow rates .

Designed for high‑performance off‑road applications , these injectors support pump gas, ethanol blends, and race fuels—while maintaining the durability and reliability expected from SouthBay.
