Looked around and found this...

So as far as I can tell the first engine, being the KA24E, was in several cars, and if you look at the second one the same motor is listed in 89 in the D21.
The KA24DE was used in the late 90's for the Frontier.
So while my source was wrong, they did still use the motor in Trucks. Apparently do the the engines good Torque ratio if I'm not mistaken.
Either I agree I have no clue what the comparisons are on the bottom end of the engine then. But it would be kinda cool to see if it would work since one of the later Frontiers was a 4wd.
Like most things if you have the money for it, then anything is possiable. Kinda wonder what a swap like that would be like.
