Weistec W.3 Turbo Upgrade (Mercedes M139) | 01-139-02369-4

MAXIMUM PEFORMANCE. STOCK LOOK

The factory turbocharger is disassembled and fully inspected. The compressor cover and center cartridge are then machined to accept our 5-axis CNC machined larger impeller wheel. The compressor cover inlet pipe is also machined as the original size would be a restriction to the new Weistec compressor 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. Custom tuning and proper supporting upgrades required for best results and performance.
