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 stay please see out other listings, we have a kit that fits under the OEM manifold.

This kit will support engines making up to 600bhp at a base fuel pressure of 43.5psi. At a base fuel pressure of 58psi, these injectors will support up to 650bhp. Also great for you guys running E85! TUNING INFORMATION IS ALSO SUPPLIED WITH THE INJECTORS!

These BOSCH EV14 injectors 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. These injectors utilize a 16-hole orifice for superior fuel atomization. DONT BE FOOLED BY OTHERS SELLING MODIFIED, SINGLE HOLE ORIFICE 650cc. These injectors are covered by our best 2yr unlimited mile warranty

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 🙂
