Mountune's extensive knowledge of the Ford EcoBoost engines coupled with our comprehensive motorsport experience provides the foundation for our high-performance 1.6L Ford EcoBoost short block assembly.
Each short block starts off as a brand new aluminum Ford Fiesta ST open deck engine block which can be strengthened with the latest Cylinder Support System before being skillfully assembled with mountune forged pistons, forged h-beam connecting rods, and tri-metal racing bearings.
This engine is the perfect foundation for your Fiesta ST for high boost applications including track day use or as a direct replacement for your tired original engine.
