Top feed conversion fuel rail engineered by Radium Engineering for Mazda 13B-REW secondary injectors. This CNC-machined billet aluminum fuel rail converts the factory side-feed secondary injectors to top-feed configuration, allowing use of high-flow aftermarket top-feed injectors for increased fuel delivery in rotary engine applications.
Ideal for Mazda RX-7 FD builds requiring high-flow secondary injectors for turbocharged rotary applications. Perfect for high-performance street, track, or motorsport builds where increased fuel delivery is critical for 13B-REW twin-turbo rotary engine performance.
Important Note: For secondary injectors only. Top-feed injectors sold separately. Requires -6AN ORB fittings for installation.
