Proper fuel delivery is arguably one of the most critical components for those looking to get all the power they can safely and reliably from an engines setup. More often than not, OEM fuel rails are incredibly restrictive and impede the fuel delivery to the injectors under high fuel pressures, where arguably having consistent fuel pressure is absolutely necessary. With the Radium Engineering Fuel Rail kit for the S13 or S14 Nissan 240SX with the KA24DE (20-0457) you can make sure that your fuel rail is able to flow all the fuel you can push through it!
This fuel rail kit is a direct bolt-on for all twin cam KA24DE engines and features a large 0.69″ ID bore to suit even the most fuel hungry engines. The fuel rail converts the OEM side feed fuel injector setup to top feed allowing the use of high flowing 14mm fuel injectors. The rail is CNC machined from solid 6061 aluminum, media blasted, black-dipped anodized and laser etched for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85

Fuel Injector Compatibility
The kit includes 2 sets of phenolic spacers (shown above in the kit contents) to suit multiple height injectors. The spacers are machined from phenolic material and offer excellent resistance to heat transfer. Use the tall spacers and longer mounting bolts to accommodate tall body injectors and the short spacers and mounting bolts for short body injectors.
Recommended Injectors for the KA24 engines:
- ID1050 xds injectors KA24de (200-500HP and E85 safe!)
- ID1300 xds injectors KA24de (400-700HP and E85 safe!)
- ID1700 xds injectors KA24de (500-900HP and E85 safe!)
- ID2600 xds injectors KA24de (600-1500HP perfect for Alcohol fueled engines Ethanol/Methanol)
This fuel rail features three ports that are tapped for 8AN ORB (ends and bottom). It also has one 1/8 NPT port (top). Please select the what fitting you will need from the drop down menu above. If you have any questions please email us we are happy to help.
Recommended accessories for the KA24de radium fuel rails:
- DMR Radium Direct Mount Fuel pressure regulator, this is a clean and simple adjustable FPR that bolts directly to the radium fuel rail for a super clean/simple install.
- FPD Radium Fuel Pulse Damper, the FPD bolts to the bottom port of the radium fuel rail and ensures smooth consistent fuel pressure which means more accurate tuning under all conditions.
