{"product_id":"ported-d-series-oil-pump","title":"Ported D-Series Oil Pump","description":"The 4Piston Racing Ported D-series Oil Pump is engineered to overcome the limitations of stock oil pumps in high-performance D-series Honda engines. Stock pumps are generally adequate up to approximately 7,000 RPM, but beyond this threshold, particularly under high temperatures, they can suffer from cavitation issues and significant oil pressure drops. This affects engine reliability and longevity during demanding use.\n\nTo address these shortcomings, 4Piston Racing meticulously modifies a brand-new OEM Honda oil pump. The process involves disassembling the pump to port and smooth the internal oil passages. This modification is specifically designed to increase oil flow by a stated 25%, ensuring a consistent and adequate supply of lubrication even at sustained high RPMs. After the porting and smoothing, the pump is thoroughly cleaned, oiled, reassembled, and repackaged, ready for installation.\n\nThis enhanced oil pump is crucial for engines operating continuously above 9,000 RPM, providing a vital layer of protection for significant investments in engine builds. It is presented as essential insurance for multi-thousand dollar engine projects, preventing potential failures caused by insufficient oil pressure at extreme operating conditions. The pump is available for D16Z6\/PO6 and D16Y8\/P7A engine variants.","brand":"4 Piston Racing","offers":[{"title":"Default Title","offer_id":52686707097912,"sku":"4PR-DPUMP","price":395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178040.webp?v=1784876077","url":"https:\/\/store.motormia.co\/products\/ported-d-series-oil-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
