Turbo Manifold Toyota 1JZ-GTE Big Turbo Hi Mount
Toyota 1JZ-GTE Type B High Mount Turbo Manifold
Developed for big-turbo Toyota 1JZ-GTE non-VVT-i builds, the Walton Motorsport Type B High Mount Manifold is designed for applications where larger turbocharger packaging and outright power capability are the priority.
Suitable for both Toyota-based builds and popular 1JZ engine conversions, the high-mount layout makes this manifold particularly relevant to modified BMW E36, BMW E46 and Nissan S-chassis applications.
Toyota 1JZ Turbo Manifold Type B – Built for Big Turbo 1JZ Builds
The Type B manifold is Walton Motorsport's larger-frame turbo solution for the non-VVT-i 1JZ-GTE.
Its high-mount configuration provides the space required for larger turbochargers while keeping the turbo and associated hardware accessible – an important consideration in competition cars, engine conversions and high-output street builds where packaging can quickly become restrictive.
This version is available with a BorgWarner EFR V-Band turbo inlet.
Toyota JJZ Turbo Manifold - Wastegate & Boost Control
The manifold incorporates Walton Motorsport's high-priority external wastegate arrangement, designed to give the wastegate strong access to exhaust flow through the collector.
The current configuration uses a 50 mm high-priority wastegate arrangement with a 60 mm port, supplied without a wastegate flange fitted. This allows the final wastegate configuration to be specified around the requirements of the individual turbo system.
Toyota & 1JZ Engine Conversion Applications
The 1JZ-GTE has become a popular engine well beyond its original Toyota applications, and this manifold can form the basis of turbo systems in:
Toyota 1JZ-GTE non-VVT-i applications
BMW E36 1JZ conversions
BMW E46 1JZ conversions
Nissan S-chassis 1JZ conversions
Other custom 1JZ-powered projects where engine-bay packaging allows
Because engine conversions can vary significantly in engine position, steering, chassis configuration and surrounding components, clearance and final turbo-system packaging should always be confirmed for the individual vehicle.
Toyota 1JZ Turbo Manifold - VVT-i or Non-VVT-i?
This manifold is designed specifically for the non-VVT-i Toyota 1JZ-GTE.
Walton Motorsport manufactures a separate 1JZ VVT-i Type B High Mount Manifold, so make sure the correct manifold is selected for your engine before ordering.
Building Your Toyota 1JZ Turbo System
The Type B manifold should be considered the foundation of a custom big-turbo 1JZ system. Turbocharger, wastegate, downpipe, intake, charge piping and supporting oil and coolant plumbing should be specified around the individual vehicle and intended use.
If you're unsure which manifold, turbocharger or wastegate configuration best suits your 1JZ build or engine conversion, contact Walton Motorsport before ordering and we can help establish the appropriate specification.

Built to Last. Backed for Life.
A lifetime warranty is easy to offer. Building a turbo manifold that's unlikely to ever need it is the hard part.
You can find the full details of the Walton Motorsport Warranty HERE
Every Walton Motorsport manifold is engineered to withstand the extreme temperatures, vibration and abuse that come with high-performance street and race applications. From material selection and fabrication to our cast collectors and proven designs, durability is built into every product.
The biggest inconvenience of a failed manifold isn't the repair—it's the downtime, the labour to remove it, and the event or track day you might miss. That's why our focus has always been on preventing failures before they happen, not simply replacing parts after they do.
We're proud to stand behind every manifold we manufacture with a Lifetime Warranty. While no mechanical component is indestructible, our goal has always been simple: build products that earn your trust by performing reliably for years to come.
Because when you choose Walton Motorsport, the last thing you should be worrying about is your manifold.
Material Selection
Every Walton Motorsport manifold starts with carefully selected 304 stainless steel tubing. Not all 304 stainless is manufactured to the same standard, and the quality of the tubing plays a critical role in the durability of the finished product.
Turbo manifolds are subjected to thousands of extreme heat cycles throughout their life. Lower-quality tubing can fatigue over time, and we've seen inferior materials crack or split along the welded seam under these conditions. That's why we specify the exact tube grade and wall characteristics we know will perform reliably in demanding street and motorsport applications.
Our cylinder head flanges are designed in-house and precision cut using modern fibre laser technology, providing exceptional dimensional accuracy and repeatability. Compared to traditional CO₂ laser cutting, fibre laser cutting delivers cleaner edges and tighter tolerances, ensuring an accurate fit and consistent sealing.
Manufacturing Process
Port-Matched Flange Construction
Rather than simply welding the runners to the face of the flange, Walton Motorsport machines each runner to pass through the flange before it is TIG welded from both sides. The ports are then hand-finished to produce a smooth, uninterrupted transition from the cylinder head into the runner.
This manufacturing method delivers several important advantages:
- Increased weld strength and long-term durability.
- Improved gas flow by eliminating abrupt transitions.
- A smoother change from the oval exhaust port to the round runner.
- Reduced turbulence for improved exhaust efficiency.
The result is a manifold that is stronger, flows better, and is built to withstand years of hard use.
Cast Merge Collector
At the heart of every Walton Motorsport manifold is our proprietary cast merge collector, designed entirely in-house.
Our latest collector design delivers the highest wastegate flow we've achieved while maintaining excellent merge efficiency into the turbine. The internal geometry provides smooth gas transitions, minimising turbulence and helping to reduce exhaust gas temperatures without sacrificing performance.
Unlike fabricated collectors assembled from multiple sections, our one-piece cast design eliminates internal joints and welds within the collector itself. This not only optimises gas flow but also significantly improves structural integrity, reducing the likelihood of collector failures that can damage turbochargers or engines.
Every design decision is made with the same objective: maximum performance, exceptional durability, and complete confidence when pushing your engine to its limits.
