Mountune's extensive knowledge of the Ford EcoBoost engines coupled with our comprehensive motorsport experience provides the foundation for our high-performance 2.3L Ford EcoBoost long block assembly.

Each long block starts off as a brand new aluminum Ford Focus RS open deck engine block which can be strengthened with the Cylinder Support System before being skillfully assembled with mountune forged pistons, forged h-beam connecting rods, tri-metal racing bearings, and a lightweight forged crankshaft.

This engine specification is designed for typical track day use and those running up to 550 hp power levels with the proper supporting modifications.

CYLINDER SUPPORT SYSTEM INFORMATION

The Cylinder Support System is a proven method of strengthening open deck engine blocks while maintaining OEM integrity. The support ring is made from aircraft grade 6061-T6 aluminum. It prevents cylinder cracking, walking, and bell-mouthing.
