{"product_id":"w-3-turbo-upgrade-for-m157","title":"W.3 Turbo Upgrade for M157","description":"The Weistec W.3 Turbo Upgrade is a performance enhancement for the Mercedes M157 engine family, offering substantial increases in power and torque. This upgrade involves disassembling and inspecting your factory turbochargers, then machining the compressor cover and center cartridge to accommodate a new 5-axis CNC-machined impeller wheel.\n\nConstructed with a billet aluminum, 5-axis CNC-machined impeller wheel, this upgrade flows significantly more air and features a lightweight design for very short spool-up times and great overall power. It is tailored for the factory M157 Garrett GT22 frame and is a 100% bolt-on installation, meaning all original oil and coolant lines connect directly to the new turbo using factory gaskets. Replacing the oil feed lines with new OEM parts is recommended, particularly for vehicles with higher mileage. To achieve maximum results, pairing this upgrade with Weistec Downpipes and Weistec High Flow Air Filters is advised, and an M157 ECU Upgrade is mandatory.\n\nThis product is NOT legal for sale or use on pollution-controlled motor vehicles. Please be aware that orders typically require 2-4 weeks for shipping as your factory turbochargers must be sent in for the upgrade process. A core exchange option is available, where upgraded turbochargers are shipped to you upfront for a refundable core charge, which is refunded once your factory turbo units are received and pass inspection.
