Description

The Weistec W.3 Turbo Upgrade is engineered to unlock the full performance potential of the Mercedes-Benz M276 3.0L Biturbo engine. This upgrade features larger impellers, precisely fabricated on a 5-axis CNC machine, and is perfectly balanced for high RPM operation, promising unparalleled performance. Installation is a simple 100% bolt-on process. This upgrade is designed to deliver substantial power gains, with advertised figures reaching up to +212 HP and +216 TQ. These gains are estimates of peak HP and Torque. The upgrade is compatible with various Mercedes-Benz models featuring the M276 engine, including the W205 C400 (2014-2015), C43 AMG, C450 AMG, and W213 E400 4-Matic.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
