Looking to convert your Nissan S13 SR20DET engine to a top feed fuel rail? Here is the kit for you! This kit includes an 11mm (oring size) high flow billet aluminum fuel rail (anodized blue), installation hardware, and a set of 4 – NEW BOSCH EV14 550cc high impedance fuel injectors. See below for a more detailed description of what is included.

This kit will fit the factory intake ALL RED top & Black top S13 engines! Some aftermarket intake manifolds will only utilize 2 of the 3 mounting points on the fuel rail (see pic). 

This kit, with the 550cc fuel injectors, will support engines making up to 330bhp at a base fuel pressure of 43.5psi. At a base fuel pressure of 58psi(4bar), these injectors will flow 630cc and support up to 380bhp.

Why switch to top feed?
– OEM style side feed injectors can be problematic, are difficult to install, and flow rate choices are limited.
– With a top feed fuel rail you have the ability to use a variety of different brands, and flow rates to accommodate your needs.
– Top feed fuel injectors are less expensive and more readily available when, or if, you need to upgrade.

What else is needed for install?
You will need an external fuel pressure regulator of your choice, and some fuel line & fittings. THATS IT!
