{"product_id":"forged-piston-kit-79mm-bore-8-8-1-compression-ratio","title":"Forged Piston Kit, 79mm Bore, 8.8:1 Compression Ratio","description":"The Supertech piston kit is a performance-focused forged component set engineered for the Mazda 1.6L B6 DOHC engine found in 1990-1993 Miata models. These pistons are crafted from high-strength 4032 aluminum alloy, offering the durability needed for high-boost turbo or nitrous configurations. Each piston features a lightweight 260g design, a round skirt, and a compression ratio of 8.8:1 to ensure reliable operation under increased stress.\n\nTechnical specifications include a 79mm bore, a 1mm oversize, a 32mm compression height, and an -11cc dome dish for optimized combustion chamber geometry. The kit is designed for use with a 20mm pin diameter and specific ring sets, such as part number R79-GNH7900. These precision-forged components provide a reliable foundation for engine builders seeking to upgrade the factory rotating assembly for forced induction or high-output naturally aspirated setups.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52663921410360,"sku":"P4-MA790-N10-4","price":658.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720530.webp?v=1784330852","url":"https:\/\/store.motormia.co\/products\/forged-piston-kit-79mm-bore-8-8-1-compression-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
