Weistec Engineering is pleased to release the M157 W.3 Turbo Upgrade. We have developed proprietary aerodynamics designed to optimize extreme pressure operation of the M157. The results are astonishing gains resulting in as much as 730 wheel horsepower.
Constructed of billet aluminum, our 71mm impeller wheel is 5-axis CNC machined and flows 53+ lbs/min of air. The light weight impeller design and latest machining technology results in very short spool up times and great overall power. Tailored for use exclusively with the factory M157 Garrett gt22 frame makes this a 100% bolt-on installation. No custom oil and water lines to leak, no headaches. Every factory line connects right to the new turbo, using factory gaskets. Replacing the oil feed lines with new OEM Oil Feed Lines is recommended, especially on higher mileage vehicles.
For maximum results, the combination of our Weistec Downpipes, and Weistec High Flow Air Filters is recommended. An M157 ECU Upgrade is required.
*Power gains vary based on model and modifications.
*Product may not be emissions compliant. Check local laws prior to installation.
