{"product_id":"mrx-2-0l-forged-long-block-engine-assembly","title":"MRX 2.0L Forged Long Block Engine Assembly","description":"The Mountune 2.0L MRX long block is a performance-focused engine assembly designed to serve as a robust foundation for high-boost applications or as a direct replacement for the factory engine in the Ford Focus ST. Each unit begins with a brand-new aluminum Ford 2.0L EcoBoost engine block, which is then precision-assembled with high-strength internal components including forged pistons, forged I-beam connecting rods, tri-metal racing bearings, and a keyed OEM crankshaft.\n\nThe assembly is topped with a precision-machined MRX cylinder head that increases intake airflow by 44% and exhaust airflow by 19%. This cylinder head is equipped with high-performance black nitrided intake valves, sodium inconel exhaust valves, and motorsport-grade valve stem seals. Customers may choose between V2 or V3 camshaft configurations based on their performance goals.\n\nThe V2 camshafts are recommended for most applications, offering a balance of drivability and power. The V3 camshafts are designed for use with larger-than-stock turbochargers to enhance high-RPM power; however, these require specific engine tuning and should be expected to produce a rough idle. All engines are built to order with current estimated lead times of 12-16 weeks. Mountune covers this assembly with a 1-year\/12,000-mile limited warranty against defects in workmanship or materials.","brand":"Mountune","offers":[{"title":"Default Title","offer_id":52663052992824,"sku":"6063-LB-201","price":13774.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687512698.jpg?v=1784323273","url":"https:\/\/store.motormia.co\/products\/mrx-2-0l-forged-long-block-engine-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
