W.3 Turbo Upgrade

The Weistec W.3 Turbo Upgrade, SKU 01-260-02218-2, is a performance enhancement for Mercedes-Benz M260 engine families, specifically designed for models like the GLA250 (H247) from 2020-2025. This upgrade transforms your factory turbochargers by disassembling them, machining the compressor cover and center cartridge to accommodate a new 5-axis CNC-machined impeller wheel. The reassembled turbochargers are then high RPM balanced for optimal operation and longevity, retaining an OEM service life. Externally, the W.3 Turbo Upgrade maintains a completely stock appearance, ensuring that the performance gains are discreet. Installation is designed to be 100% bolt-on, utilizing all original oil and coolant lines. For customers who prefer not to send in their existing turbochargers first, a core exchange option is available, where upgraded turbochargers are shipped upfront for a refundable core charge upon receipt and inspection of your factory units. To achieve the best results and unlock the full performance potential of the W.3 Turbo Upgrade, custom tuning and supporting modifications are essential. Weistec recommends their W.3 ECU calibration, TCU tune, CPC upgrade (if applicable), downpipes, upgraded spark plugs, and potentially a Water Methanol Injection System, along with high-flow air filters or carbon fiber airboxes. Please note that this product is not legal for sale or use on pollution-controlled motor vehicles in the United States. Orders typically require 2-4 weeks for shipping as your original turbochargers must be sent in for the upgrade process.
