Stage II Turbo Upgrade Kit

The RENNtech Stage II Turbo Upgrade provides a significant power boost for the AMG 53 series equipped with the M256 3.0L I6 engine. The system utilizes lightweight forged billet wheels and a reinforced cartridge shaft to handle increased boost levels, delivering improved throttle response and reduced turbo lag. Each assembly is flow-tested and fine-balanced to ensure consistent performance and longevity. To achieve the maximum power output of 540 HP and 515 lb-ft, the installation requires additional hardware, specifically a RENNtech downpipe, blow-off valve (BOV) adapters, and high-flow air filters. The use of 93+ octane gasoline is mandatory for this performance package; vehicles in regions with poor fuel quality may require a lower power setup. Please contact RENNtech for specific configuration details regarding lower power or race fuel options. This upgrade is compatible with the W213 E 53 AMG Sedan, S213 E 53 AMG Wagon, C238 E 53 AMG Coupe, C257 CLS 53 AMG, X290 GT 53 AMG, C167 GLE 53 AMG Coupe, and V167 GLE 53 AMG SUV. A core charge is required, which will be credited upon the return of your original OEM turbo core. Note that RENNtech does not accept damaged turbo cores for exchange.
