High Mount Manifold to suit Toyota 2H - T2 Flange

Radius Fabrications 2H Turbo Manifold – T2 Flange

The Radius Fabrications 2H Turbo Manifold (T2 Flange) is designed specifically to suit the Toyota 2H diesel engine, offering a strong, reliable foundation for turbocharged setups where space, simplicity, and durability are key.

Fabricated in-house using proven Radius designs and materials, this manifold provides efficient exhaust gas flow to help improve turbo response while maintaining excellent heat management and long-term reliability. It retains a factory-style footprint for straightforward installation while supporting common T2 turbocharger configurations.

Important: Product images may show a CT26 flange. Please ensure you select the correct T2 flange option when ordering.

Key Features

• Suits Toyota 2H diesel engine

• T2 turbo flange

• Precision TIG-welded construction

• Heavy-duty 16mm thick flange

• Factory-style mounting footprint

• Designed for reliable boost and long service life

• Single-scroll turbo design only

• Australian designed and fabricated

Wastegate Information

• Radius Fabrications does not sell wastegates or wastegate flanges

• If you choose to add a wastegate flange:

  • You must supply both the wastegate and flange

  • These must be sent to us prior to fabrication

• Any modification to a standard Radius manifold, including customer-supplied wastegate flanges, voids the product warranty

Installation

• Exhaust gaskets are not supplied

• Gaskets must be sourced from a local auto parts supplier

• Manifold shares the same footprint as the factory exhaust manifold

• Radius Fabrications recommends replacing engine studs during installation

• Due to the 16mm flange thickness, longer studs of the same diameter but longer to suit the thicker flange

• Manifold flange thickness: 16mm

• Any cutting, welding, or modification voids warranty

FAQ 

What engine does this manifold suit?

This manifold is designed specifically for the Toyota 2H diesel engine.

What turbo flange does this manifold use?

This manifold is built with a T2 turbo flange.

What is the exhaust manifold stud size?

• M8 x 1.5 pitch for T2 flange applications
  

Do you supply exhaust gaskets?

No.
Radius Fabrications does not supply gaskets. Customers must source standard replacement gaskets locally.

Do you recommend replacing engine studs?

Yes.
Because the flange is 16mm thick, we recommend installing longer studs of the same diameter to ensure correct clamping force and long-term reliability.

Can I add a wastegate to this manifold?

Yes, but:

• You must supply the wastegate and flange

• These must be sent to us before fabrication

• Any modification to a standard Radius manifold voids warranty

Do you manufacture twin-scroll manifolds?

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

What horsepower can this manifold support?

As a general guideline:

• Low mount manifolds: up to ~200 hp

• High mount manifolds: up to ~280 hp

• Merge manifolds: 280 hp and above

Actual results depend on turbo selection, tuning, exhaust system, and supporting modifications.
