Weistec Mercedes-Benze M133 Turbo Upgrade Service

The Weistec M133 W.3 Turbo Upgrade Service provides stock like response with increased compressor flow resulting in substantial gains* through out the power band. 

This is not a replacement Turbo Kit! This is an upgrade service for your factory Turbocharger. Ship your factory Turbo in to be rebuilt and improved by the master engineers at Weistec. We supply you a shipping label by email after purchase, once the Turbocharger rebuild is completed, it will be sent back to you ready to re-install. We understand that downtime to your vehicle isn't ideal, so the process is designed to have a turnaround as fast as possible so you can get back to enjoying your vehicle.

The factory turbocharger is disassembled and fully inspected. The compressor cover and center cartridge are then machined to accept the Weistec 5-axis CNC machined billet impeller wheel. Externally, no changes are made to maintain a completely stock appearance. The new impeller wheel supports greater power levels than the factory unit with little to no sacrifice in spool and response. The turbochargers are then reassembled with new seals and fully balanced for smooth operation and OEM service life. All the original oil and coolant lines bolt right up making for a simple install.

For maximum results, the combination of the Weistec M133 Downpipe, Midpipe, and Weistec M133 Intake upgrade is recommended. A Weistec W.3 Turbo Specific ECU Upgrade is recommended.
