    W.3 Turbo Upgrade, Mercedes M157

  • Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP

    Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.

    Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

    Fuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.

    Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel/tire size and weight will also impact chassis dyno results

    Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output

    Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.

    Supporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

M157 W.3 Turbo Upgrade

Hundreds of vehicles around the world have made the jump to the Weistec M157 W.3 Turbo Upgrade since being released in 2011. OEM appearance and reliably make the W.3 upgrade an easy decision. We have developed a proprietary compressor wheel designed to increase air flow capability of the M157. The results are astonishing gains resulting in as much as 730 wheel horsepower.



Weistec Turbocharged 2014 E63S Wagon

Constructed of billet aluminum, our larger impeller wheel is 5-axis CNC machined and flows signifigantly more 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.



Key Features

  • 5 Axis CNC Machined
  • High RPM Balanced for perfect operation
  • 100% Bolt on installtion
  • Increased Wheel Horsepower and Torque, on 91 octane with supporting upgrades
