i seem to remember the s12s in the us came with a ca20de (or ca20e) and a ca18et. sohc turbo. the later ones came with the option of the vg30e 3.0 lt v6 out of the maxima and 300zx. the 200sx came from the 2.0 ca, i just cant remember iff it was dohc (de from 2 cams and electronic fuel injection) or sohc (just the "e" for fuel injection) either way the turbo model isnt that great. nothing overly cool about it, but i love that body style.
