{"product_id":"s2v2-turbocharger","title":"S2V2 Turbocharger","description":"The BNR Supercars S2V2 Turbocharger is a performance upgrade engineered for the Mazdaspeed3 and Mazdaspeed6. It utilizes a GT28 turbine wheel and BNR's GT2860 Gen 2 billet compressor wheel, rated for a flow rate of 43 lbs\/min, and features a rear journal bearing with a high-performance 360 thrust assembly and turbine seal for durability.\n\nThis turbocharger maintains the stock 2.25-inch inlet diameter, with only minor modifications needed for boost control solenoid relocation. It offers enhanced response and mid-range power compared to the S1, attributed to its larger A\/R ratio compressor housing and an upgraded wastegate actuator calibrated to 14 psi. The unit is VSR balanced to .5 gram\/in2 and includes a BNR compressor housing upgrade and a BNR .63 a\/r turbine housing with a 27mm wastegate port.\n\nBNR Supercars prioritizes maximizing under-curve power and torque, aiming to make vehicles more responsive and fun to drive on the street. The S2 is a popular choice as a reliable replacement for stock K04 turbos, often capable of supporting up to 400-450 WHP on stock engine internals without requiring a tune, though a tune is suggested for optimal performance and to manage the 15 psi wastegate setting on some versions. The installation kit includes all necessary stainless hardware, gaskets, studs, nuts, and washers, along with an extended stainless water line.\n\nIt is crucial to note that divorced downpipes may not function correctly with BNR turbocharger upgrades, potentially leading to extreme high boost issues due to improper wastegate valve operation. For built engines, a custom oil supply line is recommended for turbocharger protection. Turbos may ship directly from BNR, so allow for additional build and delivery time.","brand":"BNR Supercars","offers":[{"title":"Default Title","offer_id":52687196782904,"sku":"BNR-S2","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662154691.webp?v=1784881286","url":"https:\/\/store.motormia.co\/products\/s2v2-turbocharger","provider":"MOTORMIA","version":"1.0","type":"link"}
