Weistec BMW S55 W.3 Turbo Upgrade

The Weistec BMW S55 W.3 Turbo Upgrade is designed to bring out the full potential of your 3.0L Twin Turbo engine. You’ll experience impressive power gains, particularly at the top end, making every drive a thrill.

Precision Engineering

We start by disassembling the factory turbochargers for a thorough inspection. The compressor cover and center cartridge are then expertly machined to fit Weistec's 5-axis CNC machined impeller wheel. The best part? The exterior remains unchanged, preserving a completely stock appearance. This new impeller wheel allows for higher power levels while maintaining quick spool and response—no compromises here!

Seamless Installation

Once the turbochargers are reassembled with fresh seals and meticulously balanced, they’re ready for smooth operation that meets OEM standards. Plus, all the original oil and coolant lines fit perfectly, ensuring a straightforward installation process.

Maximize Your Upgrade

For optimal performance, we recommend pairing this upgrade with the Weistec W.3 Turbo Specific ECU Upgrade.

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design. While the company was only established in late 2010, founder Michael Weiss and his partner Steve Atneyel both have an impressive track record of working with some of the fastest and most powerful vehicles in the world. The duo were both engineers for major American OEM and aftermarket performance companies; Michael was involved with advanced engineering, while Steve specialized in computer calibration.

Michael Weiss and Steve Atneyel decided to branch out on their own and combine their expertise and experience. The pair were, and still remain, avid Mercedes enthusiast and realized that there was a huge gap in the market for a company dedicated to engineering state-of-the-art performance systems for cars powered by motors like the M156 and M159 AMG. Since its inception over a decade ago, Weistec has grown to provide customers with the highest level of satisfaction and value through unyielding tests and continuous improvements in Mercedes products and performance.
