Application
Ford EcoBoost 2.3L
Focus ST 2013-2018

The perfect way to increase displacement and add performance when rebuilding your Focus ST engine.

mountune’s extensive knowledge of the Ford EcoBoost engine coupled with broad motorsport experience provides the foundation for our Premium High Performance 2.3L Ford EcoBoost short block. Each short block is skillfully assembled using a brand new Ford engine block coupled with mountune Forged Pistons, Forged Connecting Rods and high performance bearings. This short block is the perfect foundation for your Focus ST for high boost applications including track day use. We take the guess work out of critical engine assembly allowing you to install your existing cylinder head and other base engine components to this premium improved foundation.

The engine block is first inspected, de-burred, and the bores are honed to perfection to receive mountune Forged Pistons. The rotating assembly that includes a new Ford RS Forged 94mm crankshaft (keyed option available) and mountune Forged Connecting Rods is balanced to within .5 gram. The select parts are professionally assembled by one of mountune's skilled engine builders using tri-metal race spec bearings.
Each assembly includes a detailed data sheet showing all critical engine dimensions.
