The RENNtech performance turbo upgrade is truly the ultimate upgrade for your 45 AMG - M133 Turbo-Series!
The lightweight forged billet wheel features a dramatically larger than stock impeller (inlet side) and an increase in the turbine trim (exhaust side). This combination of high quality, light weight components coupled with less rolling resistance compensates for turbo lag despite being a functionally larger turbo. Our Turbo Upgrade uses a modified bearing and a stronger shaft, to remedy the factory weaknesses. The end result is nothing short of spectacular with the RENNtech turbo package making up to an incredible 460 HP and 415 TQ at the crank!
More power isn’t the only performance benefit as our turbo spools quicker, offer a more responsive throttle and immediate power delivery thanks to a reduction in exhaust back pressure, rolling resistance, higher RPM's and a lighter rotating mass. In addition, our turbo upgrade kit includes the RENNtech ECU Upgrade and high-performance air filter. The Turbo Upgrade has been developed in partnership with RENNtech GmbH, facility in Germany, and was tested and perfected on the Nürbugring. All parts are tested in-house as well to ensure years of 100% trouble-free and leak proof operation.
