Has anybody done an engine swap to go from gas to diesel in the US? I have a 92 Pathfinder SE with a manual tranny and was starting to look for a vehicle so that I can run biodiesel. I know that there are diesel Pathfinders outside of the US but I'm not sure how easy it would be to get an engine, get it installed and what kind of emissions testing /laws I need to worry about here in Seattle, WA.
