Sooo, I'm guessing he never got this off the ground.... Sad, as I have an S30 with dreams of doing an AWD swap. I preface this by sayig I am a Mechanical Design Engineer with tons of experience modeling. Does anyone have a good CAD file of an S30 chassis that I can use? I've designed entire race cars down to the bolts in Solidworks before and would be willing to map out/ make drawings for a project like this. Would need everyone's input on what needs to happen, however.
