It has an L engine. Some call it a 1L, but the first was just and L and the later series were 2L, 3L, 5L. Absolutely gutless. Kinda only good for saying you have a toyota diesel, though one in proper running order driven by a little old lady can get in the range of 50 mpg.
That said, I'd buy one for the right price and have looked at buying a few. Most the time they're in much worse shape than reported or have other issues, the last having been hit straight in the side with extensive cab damage and a lost title by the ladies deceased dad at a towing yard
