Just arrived Mozambique. Plenty of old JDM diesel cars here. There is no old-school engine for the Hilux, but the 70-series Land Cruiser still relies on the 1HZ engine. Australian-standards 70-series Land Cruisers with the V8 diesel are not so common but can often be found around Maputo.

Brand new diesel small cars are usually sourced from South Africa.

I'm in Angola right now, and back here it's still possible to buy a Hilux with the nearly indestructible 5L-E engine, reported to be more suitable to dirtier diesel fuels and even better to use vegetable oil as a fuel alternative due to the low-tech indirect injection. A cheaper engine, easier to perform PMS. Only downside it lacks a turbo. Diesel Corollas are not officially available thru Toyota dealers, but can be sourced from Morocco either with the same 1.4 D4-D it spots in Europe or the good ole 2C used in Philippine Corollas before the Altis.
