If you’re looking to boost your Mazda RX-7’s performance, the Radium Engineering High Flow Secondary Fuel Rail is a fantastic choice for the OEM lower intake manifold on the iconic 20B-REW rotary engine. This isn’t just any fuel rail; it’s designed with precision and crafted from high-quality aluminum, featuring a sleek anodized black finish that’s compatible with all popular fuel types, including E85. Talk about versatility!
Key Features
Large Internal Bore: This fuel rail is built to meet all your engine’s power demands, ensuring a smooth and reliable fuel flow.
Multiple Ports: With three 8AN ORB ports, you have the flexibility to connect various fittings, and the extra center port makes it easy to add fuel system accessories like the OEM fuel temperature sensor (using part number 14-0421), a pressure transducer, or even a Radium fuel pulse damper.
Injector Compatibility
Just like the stock fuel rail, this one features 11mm injector bores, allowing you to use your OEM fuel injectors without any hassle. If you’re ready to upgrade, you can easily install aftermarket Bosch EV14 style injectors when using the provided 14mm lower injector seats and insulating phenolic spacers. How convenient is that?
Designed for Performance
The injector seats are designed with versatility in mind, working seamlessly whether you choose to keep the OEM diffusers in place or not. Plus, they come equipped with FKM O-rings, making them perfect for boosted applications. Your RX-7 deserves the best!
