Mk3 Focus RS Forged Engine Rebuild - Fully Fitted at mountune HQ

The mountune Forged Engine Upgrade for the 2.3-litre EcoBoost engine native to the Mk3 Focus RS includes pistons which are manufactured exclusively for mountune in the US by MAHLE Motorsport utilising its 4032 grade alloy, and connecting rods made in the USA by Carrillo to our specification.

Once upgraded the engine can withstand significantly increased cylinder pressures and ultimately power and torque output, compared to the OE equivalents.

Recommended when exceeding 400bhp, the mountune forged engine upgrade provides owners with peace of mind that their engine will retain maximum possible reliability when running moderate, or even extreme power outputs, like the m520 conversion.

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)
  • Big end bearing shells (heat treated)
  • High Tensile Head stud/nut set (replacing OE head bolt set-up)
  • Oil control system (baffled sump - including OE balance shaft delete)
  • All required gaskets / seals
  • Timing chain tensioner
  • Engine oil & filter (engine oil changed to 10W/60 specification)
  • Coolant change
  • Hand-signed engine plaque
  • Air-con re-gas
  • mountune steel conrods
  • mountune forged pistons

In addition, the price includes a 500 mile post run-in period engine diagnostic check, with a complimentary oil and filter change.

Please note: the price shown for this product includes installation* at mountune HQ in Hutton, Essex and is not transferrable to any other Ford dealer or installer.

Please specify your preferred installation date in the 'notes' section when checking-out; our workshop team will then contact you back to confirm this date. If we can't accommodate your preferred choice, the team will discuss with you other available dates, that are still acceptable to you.

*subject to availability. Lead times may vary. Contact us for more information.
