To Suit Toyota 2H Diesel Engine, Retains Factory Turbo Location
The Radius Fabrications 2H Turbo Manifold is engineered specifically for the iconic Toyota 2H 4.0L diesel engine, designed to retain the factory CT26 turbocharger location while delivering improved flow, strength, and reliability.
Whether you’re restoring a classic 60 series, building a reliable tourer, or adding forced induction to your 2H-powered 70 series, this manifold provides a durable, bolt-on solution with modern performance characteristics.
For longevity, we recommend replacing factory studs with same-diameter, longer studs
Any modification to the manifold (such as wastegate additions or machining) voids warranty.

FAQ
What size are the manifold studs?
M10
Do you offer twin-scroll manifolds?
No, Radius Fabrications does not fabricate twin-scroll versions.
Do you supply gaskets with the manifold?
No. Customers must purchase gaskets from local automotive suppliers.
Do I need new studs for installation?
Yes. Our flange is 16mm thick, so longer studs (same diameter) maybe required.
How much horsepower can the manifold handle?
Low mount: up to 200 HP
High mount: up to 280 HP
Merge style: 280+ HP
(Actual power depends on turbo, tune, and supporting modifications.)
