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 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. Whats equally impressive is that these numbers are achieved at only 20psi, and 20 psi is only the beginning.
