{"product_id":"hi-power-rz-cams","title":"Hi-Power RZ Cams","description":"The 2JR QR25 Hi-Power RZ Cams represent the pinnacle of horsepower enhancement for the (2002-2012) QR25DE engine, a collaborative release from 2JR and JWT.\n\nThey are capable of significant power increases, with claims of up to 235 whp on race gas.\n\nInstallation of these cams requires a tune for optimal performance. Users should anticipate a loss of some low-end torque under 3000 RPM, estimated at -15 HP. However, the cams will provide substantial power above 5000 RPM and allow the engine to rev past 8000 RPM. A lopey idle is a characteristic of these high-lift cams, ensuring others will know your QR engine has been modified.\n\nIt is important to note that the cam gear is not included and cannot be used with these high-lift cams. A matched RZ valve spring set is also required. These cams are available for both 2002-2006 (Gen 1) and 2007-2012 (Gen 2) QR25 engines and will fit Sentra, Altima, and Frontier models with the 2.5L engine.","brand":"2J Racing","offers":[{"title":"Default Title","offer_id":52686677573944,"sku":"RZ1","price":701.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660670210.jpg?v=1784875849","url":"https:\/\/store.motormia.co\/products\/hi-power-rz-cams","provider":"MOTORMIA","version":"1.0","type":"link"}
