Not sure if it is similar, but we have the ED33, installed in 1986, after being pulled from one of those low km Japanese trucks, Nissan
Cabstar I believe. It's a monster of a thing, but to its credit, seems reliable. 2000 hours and still fine, though I wrecked the injectors by feeding them water
, and it has the expensive rotary vane style injector system, so that cost a pretty penny to fix. Parts
are ok, but not EASY as such. Still, so far so good, and once you sort out your supply lines you should be fine.
