Looking to convert your Nissan RB25DET Series 1 or 2 engine to top feed injectors? Here is the kit for you! This kit includes an 11mm (oring size) high flow billet aluminum fuel rail (anodized BLACK), installation hardware, and a set of 6 custom BOSCH EV14 550cc fuel injectors. See below for a more detailed description of what is included.

Note this kit must be used in conjunction with a front facing GReddy/FReddy style intake manifold. It will NOT fit under OEM intake manifold. If you have an OEM manifold, please see our other listings for out custom kit!

This kit will support engines making up to 500bhp at a base fuel pressure of 43.5psi. At a base fuel pressure of 58psi, these injectors will support up to 560bhp. Also great for you guys running E85! TUNING INFORMATION IS ALSO SUPPLIED WITH THE INJECTORS!

These are UNMODIFIED BOSCH EV14 injectors, with the multi hole orifice, and are compatible with all known fuels, including alcohol and E85. They offer fast response times, predictable flow down to 2ms, and maintain linear flow up to 8 BAR fuel pressure. Great for small-medium displacement engines making big power.

Applications:

– Nissan Skyline R33 GTS-T RB25DET (Series 1 & 2) – NON NEO
– Nissan Stagea C34 RB25DET

Kit includes:
– 1x High flow billet fuel rail (11mm o-ring). Anodized BLACK finish.
– 2 x rail spacers & cap screws
– 2 x -6an fuel fittings for inlet and outlet on fuel rail (blue)
– 2 x copper spacers for fuel rail fittings

Why switch to top feed?
– Side feed injectors are only offered in certain flow rates, and have a higher failure rate.
– 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!

Are we selling something we haven’t tested?
Never. We use this exact same fuel rail on our sponsored 240sx with the RB25DET. See the pictures 🙂
