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.
