mountune MRX 1.6L EcoBoost High Performance Short Block Engine



Application:
Fiesta ST Ford EcoBoost 1.6L

mountune’s extensive knowledge of the Ford EcoBoost engine coupled with broad motorsport experience provides the foundation for our Premium High Performance MRX 1.6L Ford EcoBoost short block. Each short block is skillfully assembled using a brand new Ford ST engine block that has been precision machined to accept a Cylinder Support System. The Cylinder Support System is a proven method of strengthening open deck engine blocks while maintaining OEM integrity. It prevents cylinder cracking, walking, and bell mouthing. The support ring is made from aircraft grade 6061-T6 aluminum.

mountune Forged Pistons, Forged Connecting Rods, bearings and a genuine new Ford crankshaft are installed all balanced to motorsport standards. This short block is the perfect foundation for your Fiesta ST for high boost applications including track day use. We take the guess work out of critical engine assembly allowing you to install your existing cylinder head and other base engine components to this premium improved foundation. Tested at over 400hp, this engine specification is designed for typical track day use and those running high power levels with supporting modifications.

Short Block Features
The genuine Fiesta ST engine block is first inspected and then de-burred. The Cylinder Support System is then installed using precision CNC machining. Once the Cylinder Support is installed, we machine the engine block deck to ensure a smooth flat surface allowing perfect head gasket sealing. The bores are honed to perfection to receive mountune Forged Pistons. Every rotating assembly is balanced to within .5 gram. The select parts are professionally assembled by one of mountune's skilled engine builders. Each assembly includes a detailed data sheet showing all critical engine dimensions and a mountune serial number. .

Pistons
mountune’s extensive knowledge of the Ford EcoBoost engine coupled with broad motorsport experience provides the foundation for the ultimate 1.6L Ford EcoBoost forged piston. Tested in house, the mountune forged piston set for the 1.6L Ford EcoBoost is a fully featured piston with many of the same upgrades we use in our professional motorsport engines.
Produced from modern lightweight alloy 4032 forgings for maximum oil control and quiet operation, each piston features supported pin bosses to withstand the extreme conditions found in engines operating with high cylinder pressures. The layout of the piston has also been optimized with weight reduction in mind and reduced skirt profiles to minimize friction. Careful consideration has been used in the “bowl” area of the piston to maintain Ford’s original profile to ensure proper and efficient combustion. Perfect for high power builds.

Connecting Rods
The connecting rod is one of the most highly stressed components within the engine and improved connecting rods are an essential upgrade for high power EcoBoost engines. The mountune connecting rod was developed using extensive FEA analysis resulting in the optimum connecting rod for applications up to 200 bhp per cylinder.Each connecting rod incorporates our motorsport DNA to provide you with the ultimate component for your engine. Exclusive features include a robust, H – Beam configuration with extensive machining to optimize weight without reducing strength. Silicone/bronze pin bushings provide a durable and low friction surface that remains dimensionally stable in high pressure and high RPM applications.

  • H Beam Design
  • Forged 4340 Alloy
  • Tapered Small End
  • C-C Length 134.02mm
  • Pin Bore 21mm Full Float
