Nissan RB25DET Top feed fuel rail kit w/ 1000cc Bosch injectors




After much anticipation we have finally released our RB25DET top feed fuel rail kit, to suit your OE Series 1 & 2 intake manifold.! Our kit is assembled with our custom cnc’d fuel rail brackets, and modern EV14 Bosch injectors, to fit UNDER your series 1 & 2 intake manifold! No need to dish out extra cash for a front facing intake. Should you decide to go with a front facing plenum in the future, our kit converts to fit that as well! This is the last top feed fuel rail kit you will ever need to purchase.

This kit includes a high flow billet aluminum fuel rail (anodized BLACK), installation hardware, and a set of 6 custom BOSCH EV14 1000cc fuel injectors. This kit is also available with a BLUE fuel rail. Please see our other listings. 

Our kit is designed to support engines making up to 900bhp at a base fuel pressure of 43.5psi, on pump. At a base fuel pressure of 58psi, these injectors will support over 1000bhp. Also great for you guys running E85! TUNING INFORMATION IS ALSO SUPPLIED WITH THE INJECTORS!

This set has been custom milled from NEW, genuine Bosch cores, and flow matched to less than 2%. We match our injectors both statically, and dynamically for optimal performance, smooth idle, and easy tune-ability. Each set is accompanied by table with all the necessary tuning information(dead time, voltage offset, latency, etc). Fuel discharge is through a single hole with a medium cone spray pattern for superior fuel atomization.

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 🙂
