W.4 Turbo Upgrade System, M157

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 bearing, featuring CNC machined billet aluminum compressor wheels capable of flowing 6large 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 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.

An Engineered Solution
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 System Weistec True Downpipes and ECU tuning) the W.4 Turbocharger System for the M157 is capable of producing 1000+ crank horsepower on 91 octane pump gas. What’s equally impressive is that these numbers are achieved at only 20psi, 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, 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 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!
