High Mount Manifold to suit Toyota 2H engine variant - T3 Flange

Radius Fabrications 2H High Mount Turbo Manifold

To Suit Toyota 2H Engine – T3 Flange

The Radius Fabrications 2H High Mount Turbo Manifold is purpose-built for Toyota 2H diesel engines, providing a strong, reliable platform for turbocharging using a T3-flanged turbocharger. Designed for improved turbo positioning, airflow, and serviceability, this high-mount configuration is ideal for performance builds, touring setups, and engine conversions.

Fabricated in Australia using high-quality materials and expert TIG welding, this manifold is engineered to withstand high exhaust temperatures and sustained boost while maintaining a factory-style footprint at the cylinder head for straightforward installation.

Note: Product images may show a CT26 flange. Please ensure you select the correct flange option (T3) to suit your application when ordering.

Key Features

• Suits Toyota 2H diesel engine

• T3 turbo flange

• High mount turbo configuration for improved access and heat management

• Precision TIG-welded construction

• Optimised exhaust gas flow for improved turbo response

• Heavy-duty 16mm thick flange

• Same footprint as the factory exhaust manifold

• Designed and fabricated in Australia

• Single-scroll turbo setup only

Wastegate Flange Option (Optional)

If you choose to add a wastegate flange:

• You must supply the wastegate and wastegate flange

• The wastegate must be sent to Radius Fabrications prior to fabrication

• Radius Fabrications does not sell wastegates or wastegate flanges

• We only weld on customer-supplied flanges

• Any modification to a standard Radius manifold voids the product warranty

This option is recommended for experienced builders requiring custom boost control.

Important Information

• Gaskets are not supplied

• Customers must source exhaust manifold gaskets locally

• Manifold shares the same footprint as the factory unit

• Radius strongly recommends replacing engine studs on installation

• Studs should be the same diameter but longer to suit the thicker flange

• Manifold flange thickness: 16mm

• Any cutting, welding, or modification voids warranty

FAQ 

What turbo flange does this manifold suit?

This manifold is designed to suit T3 flanged turbochargers.

What is the exhaust manifold stud size?

• CT26 and T3 manifolds use M10 studs

• No, Radius Fabrications does not supply gaskets. Customers should source standard replacement gaskets from their local parts supplier.

Do you supply exhaust gaskets?

No.
Radius Fabrications does not supply gaskets. Customers should source standard replacement gaskets from their local auto parts supplier.

Do you recommend replacing engine studs?

No, Radius Fabrications does not supply gaskets. Customers should source standard replacement gaskets from their local parts supplier.Yes.
Due to the 16mm thick flange, we recommend replacing studs with longer studs of the same diameter to ensure proper clamping and thread engagement.

Do you manufacture twin-scroll manifolds?

No.
Radius Fabrications does not manufacture twin-scroll manifolds.

What horsepower can this manifold support?

As a general guide:

• Low mount manifolds: up to ~200 hp

• High mount manifolds: up to ~280 hp

• Merge manifolds: 280 hp and above

Actual limits depend on turbo selection, tuning, EGT management, and supporting modifications.

Will this manifold work on other engines?

This manifold is specifically fabricated for the 2H engine.
Fitment to other engines is not recommended and will void warranty.
