Description

The Weistec W.3 Turbo Upgrade is a factory upgrade designed for the Mercedes M157 engine family. This upgrade increases horsepower and torque, offering significant gains over the stock components. The product features a proprietary 5-axis CNC-machined impeller wheel.

This turbo upgrade is tailored for the Garrett GT22 frame and is a 100% bolt-on installation, utilizing all original oil and coolant lines. It is recommended to replace the oil feed lines with new OEM parts, especially on higher mileage vehicles. An M157 ECU Upgrade is required for optimal performance, and supporting modifications like Weistec Downpipes and High Flow Air Filters are also recommended.
