The mountune forged engine short-block upgrade is the perfect basis for enhanced reliability, at greatly increased power and torque outputs for Mk3 Focus ST and Focus RS owners.
Based on a new, genuine Ford 2-litre EcoBoost block (as this is a natively closed-deck design), this off-the-shelf upgraded assembly features co-developed MAHLE Motorsport forged pistons and connecting rods made in the USA by Carrillo to our specification and can be built with either a 2-litre, or 2.3-litre Focus RS crankshaft depending on which engine capacity you require.
Each short-block is supplied fully assembled by one of our race engine builders, so you're getting the same knowledge and attention to detail applied to your build as they would to a BTCC, or Rallycross engine.
As well as the uprated rods and pistons, this upgrade replaces or upgrades a number of other key engine components to maximise reliability, these include:
Cylinder head gasket (latest specification OE)
Big end bearing shells
Rear crank seal
Balancer shaft delete
Piston squirt jets
All other required gaskets / seals
Please note: does not include a sump pan - a baffled wet sump or dry sump system is available separately, at additional cost.
Can be shipped worldwide, or can be collected / fitted at our HQ in Essex, please contact us to discuss these options in more detail.
Please allow 7-10 working days for assembly - if needed urgently please contact us prior to ordering to confirm current lead time.
