{"product_id":"big-turbo-upgrade-kit","title":"Big Turbo Upgrade Kit","description":"The JMB Performance \u0026amp; Powdercoat Caliber SRT4 Big Turbo Upgrade is a comprehensive turbocharger conversion kit engineered for the Dodge Caliber SRT4. The system centers on a machined steel adapter that bridges the gap between the factory turbo manifold and a high-performance T3 flanged turbocharger. The base configuration includes a Garrett GTW series journal-bearing 5857 turbo, which can be upgraded to various other Garrett GTW models or ball-bearing configurations to further increase airflow and power capacity.\n\nThe kit is designed to provide excellent wastegate control and rapid turbo spool, offering a robust foundation for builds targeting 500+ WHP. The included T04S compressor housing features a 4-inch inlet and 2.5-inch outlet; while engineered to clear the firewall, builders must ensure minor clearance is maintained to prevent contact during engine torque. Installation hardware includes a 3-inch stainless steel downpipe (compatible with stock or aftermarket catbacks), stainless steel oil feed lines, a high-temperature oil return line, and an adapter for integration with OEM intercooler piping.\n\nPlease note that this exhaust system may not be legal for sale or use on pollution-controlled motor vehicles. Specifically, kits configured without a catalytic converter are not legal for street or off-highway use in jurisdictions with emissions regulations and are strictly intended for closed-course competition or racing use. Consult local and state laws prior to purchase.","brand":"JMB Performance \u0026 Powdercoat","offers":[{"title":"Default Title","offer_id":52662781837624,"sku":"Caliber SRT4 Big Turbo Upgrade","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687497546.jpg?v=1784320902","url":"https:\/\/store.motormia.co\/products\/big-turbo-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
