EMS Budget Build

The EMS Budget Build is an excellent choice for stock to moderately modded applications and has the capability of around 550WHP with appropriate power adders. Featuring H-Beam Rods, Mahle pistons, CA 625+ studs (THIS ITEM IS OUT OF STOCK AND ESTIMATED FOR END OF DECEMBER 2024), and your choice of a TS block or a 2.3 block (you can read more about block choices HERE), The EMS Budget Build is a solid choice for those on a budget, who are looking for a better option vs. an OEM engine, as well as those who want to have some fun with their daily driver. This build pairs well with a drop-in turbo and a custom tune, but it can also be run without a tune on a stock application. This complete, sealed engine is ready to install in your Focus ST.

Comprehensive OEM Components:

  • New OEM parts: crankshaft, timing cover, oil pan, valve cover, oil pump, pick-up tube, chain, gear, and guide.

Performance Pistons and Connecting Rods:

  • Standard 9.5:1 MAHLE pistons and Callies H-beam connecting rods.

Advanced Engine Modifications:

  • King main and rod bearings, balance shaft delete, 10 mm CA625+ head studs (THIS ITEM IS OUT OF STOCK AND ESTIMATED FOR END OF DECEMBER 2024), new OEM head gasket, titanium retainers, and upgraded valve springs ensure optimal engine performance.
