Radium Engineering Secondary Fuel Rail for Mazda RX-7 1993-1995 (20B-REW) 20-0465
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1993-1995 Mazda RX-7 (equipped with 20B-REW 3-rotor engine swaps).
The Radium Engineering high-flow secondary fuel rail is engineered specifically for the 20B-REW rotary engine. Designed with a large internal bore, this rail supports the fuel volume required for high-horsepower builds while ensuring consistent delivery across the secondary ports. It is precision-machined from 6061 aluminum and finished with a black anodized coating for full compatibility with all fuel types, including E85 and alcohol-based blends.
This component converts the secondary fuel system to accommodate modern top-feed fuel injectors, allowing for more precise tuning and higher flow rates than the original setup. Please note that injectors are not included.
- Precision machined 6061 aluminum construction

- Converts secondary ports to top-feed injector fitment
- Directly fits 20B-REW engines found in 1990-1995 Cosmo and custom swaps
