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 Nissan SR20DET (20-0158) 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 S13 SR20DET 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
- Black Anodized Aluminum Fuel Rail-Black Anodized Aluminum 30mm Injector Seats (20-0160-04)
- 3x Stainless Steel Mounting Brackets (for tall injectors)
- 3x Stainless Steel Mounting Brackets (for short injectors)
- 6x Stainless Steel Mounting Bolts
NOTE: This fuel rail kit does NOT come standard with fittings. Fittings are purchased separately.
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 small spacers and shorter mounting bolts for short body injectors.
The picture below shows how the fuel rail ports are threaded.
