Can I run my stock efi I take with this kit


I was curious as to what horsepower numbers have been reported with this kit? Also, I have a 95 gt, I see the kit is carbed. Could that be switched out for a fuel injection setup?


  • The Ford Performance XBE Top End Power Pack is setup for a carb setup, and a replacement intake would be required to convert this to EFI. Power figures will depend on other mods done to the vehicle, tune, and carb size (or EFI setup used) but you should see approximately 320-340hp at the flywheel.

    Great power increase

    I can definitely tell the difference with this new set up on my babygirl, she's happy so I'm beyond happy with this kit, this is my first time actually buying something from "Ford performance" and it has no let me down the past 2 months.
