{"product_id":"s3-turbocharger","title":"S3 Turbocharger","description":"The BNR Supercars S3 Turbocharger is engineered as a superior bolt-on upgrade for the Mazdaspeed 3 (2007-2013), Mazdaspeed 6 (2006-2007), and Mazda CX7, replacing the factory K04 unit. This upgrade addresses the limitations of the stock turbo, such as its long shaft, small shaft width, and thrust bearing design, by incorporating increased shaft size, shorter shaft length, larger bearings, and an improved thrust bearing assembly. The S3 features a GT28 non-ball bearing CHRA with a 360-degree thrust assembly and is precision balanced to under 0.5 gram\/in2 using VSR balancing. The unit comes pre-set with a heavy-duty wastegate actuator at 14 psi and features a 30mm wastegate port and a .63 a\/r turbine housing.\n\nThe BNR S3 turbo upgrade is designed for customers seeking to maximize the potential of the stock engine without significantly sacrificing turbo response. It aims to be one of the easiest turbo upgrades to install due to its fitment within the factory K04 frame. The kit includes necessary hardware such as stainless steel studs, nuts, and washers, as well as copper sealing washers and MLS gaskets for the turbine inlet and outlet. A firewall-side extended stainless water line is also provided.\n\nNote that divorced downpipes may not always work correctly with this turbocharger upgrade, potentially causing the wastegate valves to malfunction and leading to extreme boost conditions. For built engines, a custom oil supply line is recommended for turbocharger protection, and a specific line can be purchased from Graveyard Performance.","brand":"BNR Supercars","offers":[{"title":"Default Title","offer_id":52664235295032,"sku":"BNR-S3","price":1200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687681518.jpg?v=1784335664","url":"https:\/\/store.motormia.co\/products\/s3-turbocharger","provider":"MOTORMIA","version":"1.0","type":"link"}
