The manufacturing process of “cast in sleeves” provides for economy of scale in low horsepower engines, but does not accommodate high horsepower, high boost, or larger bore sizes. Darton has engineered a superior patented (patent #6,799,541) solution by using a unique designed cylinder sleeve which when siamesed and nested, creates a solid deck of sleeve flanges held in tension, reinforcing the upper deck area and provides for individual replacement with what we call Modular Integrated Deck (MID).\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCast iron performance in an aluminum block\u003c\/li\u003e\n\u003cli\u003eImproved block integral strength\u003c\/li\u003e\n\u003cli\u003eImproved cooling\u003c\/li\u003e\n\u003cli\u003eKits can be installed by your local machine shop\u003c\/li\u003e\n\u003cli\u003e“Wet sleeve” replaceability\u003c\/li\u003e\n\u003cli\u003eFull installation manual available on website\u003c\/li\u003e\n\u003cli\u003eIncreased horsepower output potential\u003c\/li\u003e\n\u003cli\u003eHigh boost and horsepower potential\u003c\/li\u003e\n\u003cli\u003eSuperior oil and compression control\u003c\/li\u003e\n\u003cli\u003eSuperior cylinder sealing and ring wear\u003c\/li\u003e\n\u003cli\u003eStreet or strip application\u003c\/li\u003e\n\u003cli\u003eBulletproof Darton ductile iron\u003c\/li\u003e\n\u003cli\u003e130,000psi tensile strength\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Darton Sleeves","offers":[{"title":"Default Title","offer_id":47779804840232,"sku":"DTN-400-230","price":1910.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/5767\/7352\/files\/darton-sleeves-mid-honda-j-series-j35-engine-blocks-157.webp?v=1716835805","url":"https:\/\/www.tegiwa.com\/products\/darton-sleeves-mid-sleeves-honda-j-series-j35","provider":"Tegiwa","version":"1.0","type":"link"}
