90+ d21 (hardbodies) in the us came with multi point fuel injection. The throttle body looks like a tbi, but there are 1 injector per cylinder (94+ trucks have side feed type injectors, older ones and the ka24e in the other vehicles used top feed). The z24i which came in the earlier d21's have tbi with 2 injectors.

as far as a good offroad engine, i would stick with the ka24e, and possibly try out a few different cams. The truck ka24e cam develops the most power at the lowest rpm.
