Walton Motorsport BMW S55 Single Turbo Manifold

Description

Developed specifically for BMW S55 single-turbo conversions, the Walton Motorsport S55 manifold replaces the factory twin-turbo arrangement with a single, modern motorsport turbocharger.

Designed to suit both Right-Hand Drive (RHD) and Left-Hand Drive (LHD) vehicles, the manifold provides the foundation for an S55 single-turbo system while retaining practical access and packaging within the BMW engine bay.

BMW S55 Turbo Manifold – Designed Around the Garrett G-Series

The S55 manifold has been developed around the compact Garrett G-Series V-Band turbo platform, including the popular G35-1050.

This makes it particularly well suited to high-performance street, track and competition S55 builds looking to move away from the limitations and complexity of the original twin-turbo system while retaining a compact turbocharger package.

Turbo inlet options also provide compatibility with equivalent Turbosmart Frame B and HPT Frame 2 turbochargers.

BMW S55 Turbo Manifold – Wastegate & Boost Control

The manifold uses a 60 mm external wastegate port and has been designed around the Turbosmart PowerGate60.

Wastegate placement and the manifold’s merge collector arrangement are designed to provide the wastegate with effective access to exhaust flow, an important consideration when controlling boost on higher-output S55 combinations.

Building a CompleteBMW S55 Turbo System

Unlike a universal manifold installation, the Walton S55 platform has supporting components available to simplify the complete conversion.

Depending on your build specification, the system can be configured with:

3.5″ downpipe

4″ turbo intake pipe

Charge pipe to suit the factory charge cooler

Turbocharger oil and water line kit

Oil feed and return blanking fittings

Turbosmart PowerGate60 wastegate

V-band hardware for connection to a custom exhaust system

This allows the manifold to be used either as the starting point for your own custom S55 turbo system or combined with the available Walton components to create a more complete conversion package.
