Walton Turbo Manifold BMW B58 Low Mount – Type A

Description

The response-focused B58 manifold, built around turbochargers up to roughly Garrett G35 / 6262 size. Low-mount layout, 304 stainless, CFD-optimised cast collector, lifetime warranty.

Key Features:

• Built for response, not just peak power: Where the Type B chases outright numbers, the Type A targets usable power and a broad powerband – Walton’s own recommended starting point for a fast-road B58.
• Sized for compact turbos: Developed around the Garrett G30 and G35 families and the Turbosmart 6262, an upgrade path beyond the factory turbo without jumping to a larger frame.
• Low-mount packaging: Keeps the turbocharger low in the bay, which suits a street car where bonnet clearance and simplicity matter.
• Turbosmart PowerGate60 configuration: Boost-control capacity for the exhaust flow that comes once you pass the factory turbo system, with an SG50 StraightGate option for the OEM actuator.
• Ported merge collector: Investment cast and welded internally and externally, with tubing pushed through the head flange and TIG welded both sides for a smooth port transition.
• Lifetime warranty: 100% British-made from carefully specified 304 stainless.

Both wastegate configurations are the same price. Choose Type B High Mount instead if your build needs a larger-frame turbo. Built to order, typical build time 2-4 weeks.
