I too fear that the feds have painted a very large target on the backs of diesels and by 2030-2035 they will have found a way to keep new diesels out of the hands of the general public beyond commercial use applications. I have seen lots of 4BT swaps in the 80 Series Cruisers and I am pretty sure that there have been diesel swaps in some 100 Series trucks but I don't see the point with a 200. I guess if you burn up the 3UR and have deep pockets then maybe the swap/conversion listed above could be exciting but I think most would elect to rebuild or replace the 3UR with another, myself included.
