Our EFR twin-turbo kit for the Gen1 2011-2016 F150 EcoBoost represents the state-of-the-art in EcoBoost V6 turbocharging. This setup can extract maximum horsepower from 3.5L EcoBoost engines. Compatible with stock engine and stock fueling, this kit produces a conservative 500 HP/Tq on 91-93 octane pump gas. But with a built motor and upgraded fuel system this turbo kit is capable of much more. Utilizing B1-frame EFR turbos from BorgWarner (the OE supplier to Ford) allows us to achieve reliable performance levels previously seen only with LMP / Daytona Prototype High performance EcoBoost 3.5L racing engines. Full-Race aluminum upgraded radiator included.  Full-Race CAC Intercooler is recommended.  This kit requires knowledge and experience with turbos and wrenching to properly install.  It is not for the faint of heart.


  • Twin 6258 = 500-750hp
  • Twin 6758 = 550-850hp
  • Twin 7163 = 600-1000hp
