mountune 2.3L EcoBoost Long Block N1

Focus RS 2016-2018

mountune’s extensive knowledge of the Ford EcoBoost engine coupled with broad motorsport experience provides the foundation for our N1 improved performance 2.3L Ford EcoBoost long block assembly. Each long block is skillfully assembled using a brand new Ford RS engine block coupled with Supertech Forged Pistons and Forged Connecting Rods, high performance bearings and a genuine RS crankshaft. We also use a brand new genuine Ford RS cylinder head assembly, camshafts and valve train to ensure reliable performance.
This is the perfect foundation for those looking for a mild increase in performance or those that need to replace their worn or damaged original engine in their Focus RS. Upgraded forged internal components and mountune build quality allow for increased performance without breaking the bank account.

We take the guess work out of critical engine assembly and minimize downtime. We also include our RS oil control pan upgrade . This engine specification is designed for use in cars with mild upgrades and typical street use. For high boost, track days and other motorsport applications, we recommend our fully option High Performance Long Block.
