W.4 Turbo Upgrade M178

* Allow 2-3 weeks for orders to be shipped.  Turbocharger systems are made to order. Please contact tuning@weistec. com to see if a tune is available for these turbos on your specific application. The Weistec Engineering M177 / M178 W. 4 Turbo Upgrade is the key to making the most power with the M177 and M178 engines without compromise in drivability or reliability. 
The turbo upgrade, as with all W. 4 Upgrades, is a comprehensive turbo upgrade that completely replaces the factory turbocharges.  The new turbochargers are ball bearing units with CNC machined billet aluminum compressor wheels rated much higher than the stock units.  The Weistec compressor covers provide mounting for the OEM wastegate actuators and is compatible with the stock charge piping.  A 3 inch anti-surge inlet is standard to provide unrestricted flow to the compressor. 
The Weistec Turbine Housings have V-Band inlets, to allow for a cleaner and easier install, and turbine outlets that not only match the factory location, also have the same flange design to use the same Weistec Downpipes and Midpipes as the stock turbos.
