Actually, I think the KA24E engine was first used in '88 or '89 in the Stanza cars and the Nissan wagons (whatever they were called). They started using them in the trucks (with a truck camshaft, presumably) in 1990, and used this same engine, with minor changes, through 1997.
Starting in 1993 or '94 I think, Nissan came up with the KA24DE, which is basically the same engine, but with a DOHC head. I believe it was used in the 240SX and Altima, and possibly other vehicles.
In 1998, with the introduction of the redesigned truck, the Frontier, Nissan switched out the KA24E for the KA24DE, which is the first time Nissan used it in a truck (that I know of).
In general, the KA24-series engines are very tough, and are popular as truck engines because of their good torque characteristics, although the car engines got different camshafts than the truck engines did, to tune them a little differently. Usually, the people driving 240SXes who think they're nothing but "truck engines" are fixed on swapping theirs out for an SR20DET or something else, when in reality, the KA24 engines are very dependable and can be built to make a lot of power.
