I had another landrover a while back, bought it in 2001, but it got stolen in 2006. But in 2005 I splashed out and had a s/h Isuzu trooper engine fitted into it. It was the 2.8 td 4JB1 engine. This was a luverly unit, quiet, powerful,started like a sewing maching, and gave very good mpg, usually on a bit of run, regularly got 33+mpg. I find the landrover 300tdi engine rather agricultural in comparison.
just read your bit underneath, about wanting to import 4JB1 engines. I bought mine , and had it installed , by ' mervin Burgins,.

He may have some s/h units still, that he could export. He does like to haggle!! (well I do anyway) (look under engine conversions)
