The Weistec Engineering M133 W.4 Turbo Upgrade is a full turbocharger replacement solution for those looking to make significantly higher power than the stock frame turbocharger is capable of generating.
The turbo upgrade, as with all W.4 Upgrades, is a comprehensive turbo upgrade that completely replaces the factory turbocharges and exhaust manifolds. For the M133 engine, the W.4 Turbo is based on the Garrett GTX3071r Gen 2 ball bearing units with CNC machined billet aluminum compressor wheel rated much higher than the stock unit. The Weistec compressor cover provides mounting for the OEM wastegate actuator, is compatible with the stock charge piping, and has provisions for the Weistec Anti Surge Valve. A 3-inch inlet is standard to provide unrestricted flow to the compressor wheel.
The entire system will mate up with the stock downpipe or the Weistec M133 Downpipe.
