is it the same bolt pattern? the rf was the first ranger engine? the perkins? it was a 2.2 and different deal iirc...
the rf...its the same critter that ss in the escort...different then the ranger.
i would just go right to the jdm market...it is still in production in one form.
just use the zuk trans, and t case if you need 4x4..
google it, maybe they are the same, but i been looking at the little diesels for years, and when it comes to these useless powerless cowards, the japanese domestic market guys are the best way to go.
the thought of swapping in less then 120 crank hp into something to drive daily makes me cringe.
