2014 Weistec Engineering E63s Sedan

This is a fully built Weistec M157 E63S Sedan. There was no expense spared on this car and it has every Weistec option for the M157 platform. Please refer to the photos of the build sheets for this car and contact us if you have any questions.

As the global leader in Mercedes Benz AMG Tuning, Weistec Engineering sets the performance standard for bi-turbo M157 performance calibration. Designed in-house by our expert tuning staff, our M157 ECU tune has surpassed the 600-wheel horsepower mark on a completely stock vehicle with no other modifications. This tune is also 100% street-legal!
M157 W.4 TURBOCHARGERS
Taking a giant leap ahead of all other available upgrades, the M157 W.4 Turbochargers completely replace the factory units. They are ball bearings, featuring CNC-machined billet aluminum compressor wheels capable of flowing 6 large amounts of air. To feed these monster turbochargers, completely new intake tubes are included. Weistec Carbon airboxes are an optional upgrade. The Weistec Turbo-Folds provide a significantly increased flow of exhaust gasses compared to the stock turbo-fold. The Weistec M157 True Downpipes perfectly mate up to the M157 W.4 Turbochargers to ensure minimal restriction once the exhaust gasses have gone through the turbine.
The W.4 Turbochargers are the most capable production turbochargers available for the M157 engine. When all supporting upgrades are purchased, (supporting upgrades: M157 ASV/Water-Methanol Injection SystemWeistec True Downpipes and ECU tuning) the W.4 Turbocharger System for the M157is capable of producing 1000+ crank horsepower on 91 octane pump gas. What’s equally impressive is that these numbers are achieved at only 20 psi, and 20 psi is only the beginning.

CONTROL = RELIABILITY
While the M157 engine is a very robust engine in factory form, a couple of weak links have been found at extreme power levels. The most common is a bent connecting rod. If the engine is producing a sustained 1000 lb-ft of torque or more, all it takes is one knock event to bend a rod. This was taken into consideration with the ECU tuning for the W.4 Power Package as they can make far more power and torque than a stock M157 engine can handle. With our optional ECU Tune for the W.4 package, the boost is controlled and tapered up to the peak of 20psi as RPM’s increase. This creates a broad torque curve that remains under 800 lb-ft (at the wheels) while allowing power to continually increase towards the redline, minimizing stress on the rods as well as the rest of the drivetrain. With a fully built M157 and other supporting upgrades, expect to see significantly higher power numbers as the Turbochargers can flow enough air volume for 1400+ crank horsepower!
Weistec Engineering offers True Downpipes for M157 AMG and M278 powered vehicles. Replacing the small and restrictive factory downpipes delivers significant gains in power, throttle response, and exhaust tone.
Engineered and designed with the most sophisticated Computer Aided Design tools, excellent fitment, and the highest performance possible are guaranteed. Each downpipe has a specially designed CNC machined turbo outlet flange, transitioning into a 3-inch pipe and low-profile V-Band flanges to mate with our Midpipes.
Downpipes come standard with external Titanium Ceramic Coating and internal Copper Ceramic coating to keep heat inside the piping, helping improve exhaust velocity and reduce engine bay temperatures.
Branded Weistec stainless steel heat shields are also included to block rising heat from the exhaust manifold.
Our Biturbo Midpipes bolt to the Downpipes using a low-profile V-Band flange and transition to the factory axle-back. Each Mid-pipe has stainless steel brackets for solid bolt-in fitment and is made of 3-inch stainless steel piping creating a very high-flowing quality exhaust system.
The Weistec ASV/WM Injection System adds multiple beneficial components to the M157 BiTurbo 5.5L engine. The first is the addition of a Weistec Anti Surge Valve (ASV). From the factory, the M157 engine was never given any type of bypass valve. Without a bypass valve, the turbochargers are subject to compressor surge when the throttle closes after hard acceleration. Compressor surge can be damaging to turbochargers and generally should be prevented to help ensure the best performance from the turbochargers. The Weistec ASV is operated by the engine vacuum, opening when the throttle closes allowing the compressed air to be vented to the atmosphere instead of back flowing into the compressor housing and stalling the compressor wheel. The vented air produces the "blow-off" sound common on many modified turbocharged vehicles. This specific product is for the bigger-bodied SUVs that feature either the M157 or the M278 engines.

Second, is the Water/Methanol Injection (WMI) System. Water/Methanol injection has been in use for several decades in multiple applications. Originally, it was used to reduce knock while increasing power and performance in aircraft engines. Eventually, it came to be used in the motorsports industry where it was found to have substantial benefits on turbocharged engines. The Weistec ASV/WMI System features a Water/Methanol Controller with a built-in MAP sensor. This controller is a progressive controller that slowly increases injection as boost builds, resulting in a smooth and seamless operation. The included Turbo Charge Pipes each have a built-in bung, allowing the use of two injectors for uniform injection and cooling. The combination of the cooling effects of methanol and the knock resistance of water results in significant gains in horsepower* and torque* as well as a reduced chance of heat soaking the intercooler system.
This system is a complete, bolt-on system that can be installed without any guesswork or custom fabrication. Weistec has engineered and manufactured many of the components of this system to ensure a simple and straightforward installation. The gains in performance and consistency make this system an essential upgrade for the M157 engine.
Our forged pistons and billet rods are designed as superior replacements for OEM pistons and rods. The pistons use a wrist pin that is stronger and of a better design than the OEM pin. The billet rods, which are of a stronger material and design than the original rods, are capable of supporting much higher power levels than the factory rods. Optional ceramic-coated piston tops to increase the heat resistance and optional Teflon-coated skirts to reduce friction.
