The Toyota 1HD-T is a 4.2 liter turbodiesel inline-6 with a cast-iron block, direct injection, and an intercooled turbocharger. It is known for low-rpm torque and long service life, which is why it is a popular choice for Land Cruiser restorations and diesel swaps.
This is a used engine. It was originally fitted to non-US-market vehicles, so it is offered here for swap and restoration use. The 1HD-T was never sold in the US, and it meets only older diesel emission standards, so confirm your state emissions and registration rules before buying for on-road use.
There are several engines in this family. The 1HD-T is the 12-valve SOHC version; the later 1HD-FT and 1HD-FTE are 24-valve and, in the FTE, electronically controlled. Confirm which engine you are receiving and which one your project needs.
| Item | Details |
|---|---|
| Variant | 1HD-T (12-valve) versus 1HD-FT or 1HD-FTE (24-valve); confirm by serial |
| Donor application | Land Cruiser 80/70, early Hilux, or Coaster |
| Emissions and registration | Older diesel standard only; confirm your state rules |
Confirm the exact engine variant (1HD-T versus 1HD-FT or 1HD-FTE) by serial number.
Confirm what is included: long block, or complete with turbo, injection pump, and manifolds.
Confirm compression or leak-down results, mileage, and oil and coolant condition.
Confirm your state emissions and registration rules for a non-US-market diesel swap.
| Item | Details |
|---|---|
| INCLUDED | The Toyota 1HD-T engine as confirmed by serial. Exact configuration (long block versus complete with turbo and injection pump) is documented before shipping; call to confirm what is in the crate. |
| NOT INCLUDED | Transmission, ECU or wiring (unless confirmed), engine mounts, exhaust, and emissions equipment for a US install are not included unless specifically confirmed in writing. |
| Tools You Need | Professional diesel engine installation only. A swap of a non-US-market diesel requires correct mounts, fueling, cooling, and an emissions and registration plan for your state. |
This engine is the Toyota 1HD-T 4.2L turbodiesel inline-6. The applications below reflect the real 1HD-T, not the engine listed in the live additional-info field (which incorrectly named a 3RZ).
| Vehicle | Compatibility |
|---|---|
| Toyota Land Cruiser | 80 Series and 70 Series (1HD-T) |
| Toyota Hilux | Early diesel models (where fitted) |
| Toyota Coaster | Bus applications (where fitted) |
The 1HD-T was fitted to the Land Cruiser 80 and 70 Series and some early Hilux and Coaster models, none of which were sold in the US with this engine. The live 'compatibility' field said '1994 Toyota 3RZ engine,' but the 3RZ is a 2.7L gasoline inline-4, a completely different engine; that entry is an error and does not describe this part. Confirm your exact application and variant by serial before you order.
Not sure which 1HD variant your project needs? Call (240) 301-0095 or email support@vazautosolutions.com with your vehicle, your target application, and the engine serial. We will help confirm the variant, what is included, and what a non-US-market diesel swap involves for emissions and registration in your state.
Quality control for this part includes:
Because this is a used diesel engine, we inspect the turbo, the injection system, and the oil and coolant for signs of wear or contamination, and we document mileage and donor history where known. Request compression or leak-down results before purchase.
