Show original supplier 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. Included 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. This 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.
