Radium Secondary Fuel Rail - Mazda Cosmo JC (20B-REW)
Couldn't load pickup availability
The Radium Engineering high flow secondary fuel rail is for the OEM lower intake manifold found on the Mazda 20B-REW rotary engine. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. The three 8AN ORB ports are featured on this fuel rail. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421), a pressure transducer, Radium fuel pulse damper, etc.
Like the stock fuel rail, the rail features 11mm injector bores permitting the use of OEM fuel injectors (shown below).
When the provided 14mm lower injector seats and insulating phenolic spacers are used, aftermarket Bosch EV14 style injectors can be used (shown below).
The injector seats were designed to be compatible with or without the OEM diffusers in place. They feature Viton O-rings making them suitable for boosted applications.

The team took a mostly broken car after some work done elsewhere, and have systematically made it reliable and fast for a fair price. The staff are invested in the work they do which also makes a big difference.
