Radium Top Feed Secondary Fuel Rail Conversion Kit | Mazda 13B-RE (20-0446)
Product details
Description
The Cosmo's two-rotor sibling gets its own secondary conversion, thirty years overdue.
The Radium Engineering Top Feed Secondary Fuel Rail Conversion Kit for the Mazda 13B-RE serves the two-rotor originally found in the 1990-1995 Mazda/Eunos Cosmo: a high flow aluminum rail, anodized black for compatibility with all popular fuel types including E85, converting the 13B-RE's secondary positions to common top feed injectors with a large internal bore behind them. The RE's larger secondary ports distinguish it from the RX-7's 13B-REW, and this rail is machined for the RE specifically. Injectors sold separately.
What You'll Feel
- Modern top feed injector options opened to the Cosmo two-rotor's secondaries
- Delivery headroom for boosted 13B-RE builds and swaps
- E85 confidence through the anodized construction
- Serviceable hardware replacing unobtainable factory parts
Features
- Top feed secondary conversion rail for the Mazda 13B-RE (1990-1995 Cosmo)
- CNC machined aluminum, anodized black; large internal bore; ORB ports
- Converts secondary positions to common top feed injectors (not included)
- 13B-RE specific; the 13B-REW uses Radium's separate rail family
The Details
The 13B-RE occupies its own corner of rotary history, the Cosmo's two-rotor with unique injector and port specifications that RX-7 parts do not serve, and the conversion follows Radium's rotary pattern: aftermarket top feed injectors seat into the provided injector seats pressed into cleaned OEM ports with lubricated O-rings, OEM style injectors skip the seat step, and plumbing adapts to the rail's ORB ports per your system. Verify injector compatibility against Radium's documentation, pair with the appropriate primary solution for the build, and run the leak check before the first start.
Kit Includes
- 1x Anodized top feed secondary conversion rail with injector seats and mounting hardware
- Injectors and plumbing fittings NOT included
Applications
- Mazda 13B-RE two-rotor (1990-1995 Mazda/Eunos Cosmo, swaps)
- NOT for the 13B-REW; see Radium's REW rail family
