{"product_id":"1-8l-4-cylinder-engine","title":"1.8L 4-Cylinder Engine","description":"The Acura B18A1 is a 1.8-liter, 4-cylinder engine known for its use in the 1990-1993 base model Acura Integras. This non-VTEC engine, often referred to as an LS motor, came equipped with an OBD0 electronic control system. It has a bore x stroke of 81 mm × 89 mm and a compression ratio of 9.2:1, with a displacement of 1,834 cc.\n\nThis engine is a popular choice for swaps and builds due to its robust design and aftermarket support. While the B18A1 initially came with OBD0, a change to OBD1 ECUs in 1992 resulted in a 10hp increase. Discussions around engine builds often reference the B18A1 for its potential, with some sources noting that the B18A1 cylinder head can fit a B18B1 block.","brand":"Acura","offers":[{"title":"Default Title","offer_id":52664178180408,"sku":"B18A1","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/686905475.jpg?v=1784334809","url":"https:\/\/store.motormia.co\/products\/1-8l-4-cylinder-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
