Product Description

Are you running more E85 or making more power on pump gas than your HPFP (High Pressure Fuel Pump) can support?  

Looking for an inexpensive option to supply more fuel?  

Then this option is for you!

For those of you that are looking for a budget conscious kit but don't want to sacrifice performance or reliability we have developed a DIY port injection option for your N55 F-Series.  This kit will provide you with the additional fueling capacity that you need  to run E85 on your stock or upgraded turbo at a bargain price!

All of our DIY kits feature the following:

  • Optional fuel return port
  • Optional boost reference port
  • 100% billet aluminum construction
  • Machined to clear HPFP hardline line
  • OEM gasket grooves with gasket retention tabs
  • 45 degree injection angle on all cylinders for better fuel distribution across both intake valves. (No cylinder 1 offset spraying the intake runner wall)

In addition our DIY kit offers a multitude of options that lets you configure a kit to meet your power goals and still stay within budget!  Simply follow our easy step by step selections to complete your custom kit.

Step 1:  Choose Your Platform

  • Let us know what car you'll be installing your new port injection kit on so we can configure your options accordingly.

Step 2:  Choose Your Injectors

  • Our kits require Bosch 42mm injectors and we have two flow matched options for you to choose from.
    • 550cc injectors are recommended for up to 700whp on E85 or 600whp on methanol
    • 750cc injectors are recommended for over 700whp on E85 or 600whp on methanol.  Other than the additional expense there aren't any drawbacks to running the larger injectors.

Step 3:  Choose Your Fuel Source

  • Low Pressure Fuel Line
    • Select this option if you will be tapping in to the stock low pressure fuel system and we will include our exclusive Cam-Lock! fuel fitting that can be installed just before the HPFP.
  • Methanol Kit
    • If you will be running methanol as your secondary fuel source, select this option and we will include a 36 inch -6an stainless steel braided fuel line and adapter for your existing 1/4" meth line.

Step 4:  Upgrade Your Fuel Lines

  • Select this option to upgrade your stock fuel lines to E85 compatible -6an fuel lines (requires that you have selected the Low Pressure Fuel Line as your fuel source).
  • If you already have our ethanol sensor, let us know when you order and we will cut your line to the correct length and install the correct connector for you.
  • Stage 4 LPFP coming soon...

Step 5:  Add an Ethanol Sensor and Bluetooth Analyzer (requires upgraded fuel lines)

  • Select this option t to run an ethanol sensor and our Bluetooth analyzer to read your ethanol content.
    • + Bluetooth analyzers require our app to view ethanol content on your Apple or Android device.

Step 6:  Choose Your Port Injection Controller

  • To run port injection you MUST run a port injection controller as this is what controllers the additional injectors.  We offer 3 options:
    • BMS JB4 controller
      • We recommend this option if you are running a JB4 as it integrates directly with the JB4 and can not operate without a JB4.
    • Split Second Flash Only
      • If you aren't running a JB4, you'll need to select this option.
    • Split Second JB4 Integrated controller
      • This options if for those that are running a JB4 and for whatever reason don't want to run the BMS controller.
  • All controllers for the F-series include a new OBDII cable for the RPM signal

Step 7:  Return Kit

  • Coming soon...
