{"product_id":"stage-i-turbo-upgrade-m133","title":"Stage I Turbo Upgrade M133","description":"The RENNtech Stage I Turbo Upgrade is engineered to be the ultimate performance enhancement for your 45 AMG M133 Turbo-Series engine. This kit features a lightweight forged billet wheel with a larger impeller and increased turbine trim. Modified bearings and a stronger shaft address factory weaknesses, while reduced rolling resistance and less back pressure contribute to quicker spooling and a more responsive throttle.\n\nIncluded in the package are upgraded turbos, the RENNtech ECU Upgrade, and a high-performance air filter. The system is fine-balanced as an assembly and has been tested and perfected on the Nürburgring in partnership with RENNtech GmbH. All components undergo in-house testing for reliable, leak-proof operation.\n\nThis turbo upgrade is designed for the M133 engine and provides significant power gains, taking the stock 355 HP and 332 lb-ft to an impressive 460 HP and 464 lb-ft at the crank. To achieve maximum power levels, the RENNtech downpipe is required. A core charge applies and is credited upon the return of the OEM turbo core.","brand":"RENNtech","offers":[{"title":"Default Title","offer_id":52663472423224,"sku":"PKG.09.133.1010","price":5980.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687612790.jpg?v=1784327234","url":"https:\/\/store.motormia.co\/products\/stage-i-turbo-upgrade-m133","provider":"MOTORMIA","version":"1.0","type":"link"}
