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

The factory turbocharger is disassembled and fully inspected.  The compressor cover and center cartridge are then machined to accept our 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 our Weistec M133 Downpipe and Midpipe, and Weistec M133 Intake upgrade is recommended.  A Weistec W.3 Turbo Specific ECU Upgrade is recommended.

*Power gains vary based on model and modifications.
