Toyota LandCruiser 70 Series 2.8-litre turbo diesel four-cylinder coming, V8 to live on (1 Viewer)

If I was going to name a 'flop' engine it would be the 1KZ. In the early 1990s Toyota could have learned from the presumed problems of the early 2L-T and made a winner of a diesel engine, 4 cylinder DI with 16 valves (or even 8); as Dougal says, a 4 cylinder 1HD-T (or -FT) with a capacity of 2.8 to 3.0 litres and an OHC. Toyota had launched the 13B and 11B engines almost a decade earlier, so DI was nothing new. Instead they stayed with the dinosaur tech IDI and made an engine which was not really rugged enough for the Land Cruiser. They also could have developed this 4 cylinder into a cheaper and more economical base engine than the 1HZ. With the benefit of hindsight, seems like a very obvious poor decision.

Spotted at the supermarket today. Another 100 series with about 400,000km on it:

Might be unpopular here but rual/outback Australia has proven the 1vd. It's a very underrated engine, i personally know of 3 farm utes with 600,000+kms and they get purely abused other than been regularly serviced. The 1hdfte, 1hz (n/a) and 1kd are the only other engines that last out here.

15 litres/100km x 600,000km = 90,000 litres of diesel.

15 litres/100km x 600,000km = 90,000 litres of diesel.

Harvest is 25,000 liters per day.

DI B series for the win! What is the 1GD, DI ?

Yeah all the commonrail are direct injection.

Bit of a mystery how Toyota claim it was the most efficient engine in class, yet the Hilux with it drinks more than anything else in class: Toyota GD engine - Wikipedia - https://en.wikipedia.org/wiki/Toyota_GD_engine

I do laugh at all manufacturers claims of improved efficiency, it just does not translate to the real world. What does partially translate is improved emissions but mostly now days that is done through after treatment, not actual engine improvements.

Couple of cases, my 1HDFTE vs my Dads 1VD, same route, same van and I used 2L/100km less. Further more my 13BT BJ74, towing the same van for a few hundred km, 10L/100, not bad for a base engine design from the 60s/70s. Emissions though are completely different.
