{"product_id":"94mm-bore-aluminum-engine-case","title":"94mm Bore Aluminum Engine Case","description":"The EMPI AL-16-01698 is a \"Super Case\" aluminum engine case, engineered for Volkswagen Type 1 air-cooled engines that demand enhanced strength and versatility. Unlike magnesium cases that can warp or pull studs under stress, this heavy-duty aluminum alloy casting provides superior structural integrity and longevity. It is ideal for building high-revving street cars or rugged off-road machines, offering a rigid backbone to maintain perfect alignment of internal components under extreme conditions like high compression or turbocharging. The increased material thickness in key areas ensures durability.\n\nThis case comes pre-machined with a 94mm bore, ready for big-bore cylinders, and features a \"Bubble Top\" raised roof design that provides internal clearance for crankshafts up to 86mm stroke, eliminating the need for manual grinding. It is also pre-drilled and tapped for full-flow oiling and includes shuffle pins on all main saddles to prevent case half movement. Additional features include a reinforced #3 cylinder area and a universal dual-bypass oiling system.\n\nFitment includes Volkswagen Type 1 Beetle and Karmann Ghia (all years\/models requiring 10mm head studs), Type 2 Bus (1950-1971 with Type 1 engine configurations), and Type 181 Thing (1973-1974). It is also suitable for custom applications like sand rails, dune buggies, and trikes utilizing Type 1 engine architecture. It is specifically machined for 10mm cylinder head studs and 94mm cylinder barrels.\n\nInstallation requires fan shroud modification due to the \"Bubble Top\" design; the bottom lip of the shroud may need trimming for a flush fit. Thorough pre-assembly cleaning of all oil galleries is mandatory to remove any manufacturing debris.","brand":"EMPI","offers":[{"title":"Default Title","offer_id":52687945302328,"sku":"AL-16-01698","price":1296.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664707486.webp?v=1784887885","url":"https:\/\/store.motormia.co\/products\/94mm-bore-aluminum-engine-case","provider":"MOTORMIA","version":"1.0","type":"link"}
