{"product_id":"2-3l-ecoboost-short-block","title":"2.3L EcoBoost Short Block","description":"The Engineered Motorsport Solutions EMS-BADASS-SB short block serves as a robust foundation for high-horsepower builds in the 2015-2023 Ford Mustang EcoBoost 2.3L (S550\/S550.2 chassis). The assembly features a new or used ST or MZR core block, a new-pinned OEM crankshaft with a matched crank gear and balancer, and MAHLE forged pistons available in standard or high-compression options. Connecting rods are Wiseco Boostline H-beam with ARP 2000 fasteners, paired with King race-spec main and rod bearings.\n\nThe design incorporates a balance shaft delete to reduce rotating mass and minimize failure points, while preserving essential piston cooling with OEM oil squirters. This short block is capable of handling 700+ whp on 93\/E85 fuel with appropriate supporting modifications, and can be upgraded to over 1000+ whp with the addition of cylinder sleeves. Each unit is built and dyno-validated by EMS, drawing on over 30 years of engine-building experience.\n\nThis product is a short block, meaning the cylinder head, head studs, head gasket, gasket kits, and timing components are sold separately. EMS strongly recommends their \"Must-Haves\" bundle, which includes OEM head gaskets and CA625+ head studs, for optimal performance and reliability. Installation requires careful attention to detail, as incorrect assembly or timing by non-EMS technicians is not the responsibility of EMS. For those uncertain about the installation process, EMS offers paid consultation services. Configuration options include block type, piston compression ratio, and shipping method, with various optional add-ons like cylinder sleeves, a Ross Damper, and an upgraded rear main seal available.","brand":"Engineered Motorsport Solutions","offers":[{"title":"Default Title","offer_id":52687954116920,"sku":"EMS-BADASS-SB","price":4745.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664707694.webp?v=1784887997","url":"https:\/\/store.motormia.co\/products\/2-3l-ecoboost-short-block","provider":"MOTORMIA","version":"1.0","type":"link"}
