I've owned a pile of 80 and 60 series land cruisers. A couple of them were right hand drive, imported into Canada. Though the 1hd-t and 12-ht were interesting, they weren't all that special and very difficult to source parts for. These nutless-wonder toyota diesels both pulled about 16-17 mpg. Neither approached 300 ft lbs of torque.
Random land cruiser memory:
Built an fj 60 for a movie where they would be doing action scenes with Jason Mamoa's big, arrogant ass in the back, with a half ton of camera gear and crew. I was afraid they'd tip it. So I rebuilt the stock-height leaf springs with modified f-350 add-a-leaves, installed a rear sway bar, and installed all new perch, shackle and spring bushings. The name of the movie was Sugar Mountain, by Yellow Brick Films.
Anyhow, our 300 ford inline six or 292 chevy inline six can be built for 1/4 the cost and they blow the doors off the landcruiser diesels. Much better work engines for towing.
Then my 6bt cummins-powered dodge exceeded the overseas toyota diesels with nearly double the torque and pulled better than 20 mpg.
