The Ford YB engine is legendary in motorsport, and people are always wanting more and more from their YB engines. So we introduce you to our version of the YB manifold. Suited to a Garrett G Series Turbo (G25, G30 or G35) and compatible with RWD Conversions such as Mk1 and Mk2 Escorts it's the perfect solution to update your Ford YB with a modern turbo.

There's no shortage of Ford YB Turbo Manifolds available. The construction methods we use set our product apart from the rivals.

Ford YB Turbo Manifold Construction

Material Selection

First and foremost not all 304 Stainless steel is created equal. We carefully select the exact specification of the tube that we use. The use of poor-quality tubes can compromise the whole design. For Instance, Turbo Manifolds experience repeated high-temperature cycles. In these situations, we have seen poor tubing split along the seam.
We design the head flanges in-house. However, we outsource the precision Fiber Laser Cutting. The use of more modern Fiber Laser cutting allows for increased accuracy over traditional laser cutting

Processes

Where the manifold meets the exhaust ports, Walton Motorsport's process is to push the tubing through the head flange and TIG weld each side. This process is followed by a selection of finishing tools. We do this to create a smooth port for the gasses to freely flow through. Consequently, this process greatly increases the durability of the manifold. Rather than using the traditional method of welding the tube to the face of the flange. Moreover, our method is where we also face the problem of an oval port needing to transition smoothly to a round tube. The stubs process, in short, helps increase power through the improved flow.
The collector we use is a custom billet merge collector. We proudly designed this collector in-house to exceed the performance of our previous market-leading hand-fabricated version. The freedom of design we have utilizing the complex 5-axis mill production process really allows us to be a step above the competition by allowing precision boost control on our unique wastegate ports. The machining process over traditional fabrication ensures that there is no danger of small fragments breaking off at high temperatures. These fragments will then make their way through your expensive turbo. We don't need to tell you how bad that can be. And did we mention its machined in the UK?

Lifetime Warranty

Bombproof? We haven't found out yet. Walton Motorsport has designed the manifolds to put up with some serious abuse though. We offer a lifetime warranty on our products as many do. However, we put a huge emphasis on the strength and durability of our products to stop them from failing. The biggest inconvenience when it comes to a failed manifold (providing none of it ends up inside your turbo or engine) is removing it for repair. By eliminating the failure in the first place, we can honestly say it would be extremely unlikely to experience a failure of our products. Consequently, We wouldn't sleep well at night if our product failed and cost you a result.

Ford YB Turbo Manifold Features

Carefully selected 304 Stainless steel tube. Working to eliminate the risk of material failure.
Fully Purged welded. Subsequently improving gas flow leads to increases in power and lowered response times.
Our unique in-house designed and UK-manufactured billet collector. Resulting in high strength, durability, and turbo lifespan.
Multi primary pipe wastegate port design developed with leading engine tuners to allow high control and remove boost creep.
Fully Smoothed Head Ports designed to optimize gas flow. As a result, providing an increase in power and lowered response times.
Optimized for use with Turbosmart Wastegates 40-50mm.

Ford Escort Mk1/Mk2 Fitment Notes

For clearance, the brake servo must be removed, along with a pedal box to bring the master cylinders inside the vehicle.
Hydraulic clutch conversion advised to aid downpipe routing
Ideally suited to WorldCup cross member and engine mounts
Designed to work with the Garrett G Series Turbos up to G35-1050

Ford Sierra/Escort Cosworth Fitment Notes

Custom downpipe and boost pipes will be required as it is not OEM location.
4WD downpipe routing is tight when using a plumb back wastegate due to the transfer box. But 3" is possible. This is easier on Left Hand Drive Cars
Wastegate positions not suitable when ABS pump us located on same side as manifold, will need custom position.
Designed to work with the Garrett G Series Turbos up to G35-1050
