(Gaskets available seperately)\u003cbr\u003e• In order to cope with the demands of high outputs, strength analysis and tests have allowed optimisation of compression ratio for flexibility of setup and high boost use. \u003cbr\u003e• Piston crown had 3D design in consideration of stock direct injection system.\u003cbr\u003e• Stock pistons skirts overhang from the block during bottom of travel. Short height pistons have revised potential issues in this area. \u003cbr\u003e• Friction, weight and other design properties to suit the needs of short height pistons. \u003cbr\u003e• Stock Bore Compatible 86.0mm \u003cbr\u003e• In order to maintain the engine block strength, the stock bore size is maintained meaning there is no need for cylinder liners\u003cbr\u003e• Reduces the cost of installation as liners, bore \u0026amp; hone and block facing processes are unnecessary. \u003cbr\u003e\u003cbr\u003eConnecting Rods:\u003cbr\u003e• Specific connecting rods have been designed to suit the longer stroke. \u003cbr\u003e• With no engine modifications, a special size crank pin has been set requiring new bearings. \u003cbr\u003e• Note: The con rod bearings are sized to use Nissan RB26 \u0026amp; SR and must be purchased separately. \u003cbr\u003e• Cast I beam design and revised connecting rod bolt size. \u003cbr\u003e\u003cbr\u003eCrankshaft \u003cbr\u003e• Stroke 90.0mm\u003cbr\u003e• Made from HKS special forged material \u003cbr\u003e• Perfect pin journal size was selected by merticulous analysis and experiment for extended stroke. \u003cbr\u003e• Carefully designed weights balance the engine for maximum efficiency.\u003c\/p\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":29610540204145,"sku":"21004-AT002","price":2460.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9099\/9409\/products\/2.1L_HKS_Stroker_Kit.jpg?v=1567093595","url":"https:\/\/www.fensport.co.uk\/products\/2-1l-hks-stroker-kit","provider":"Fensport Performance","version":"1.0","type":"link"}
