It is possible and has been done. Not very easy i'm sure. I am planning to look into this. I have access to a few junk cars that are equipped with ABS. I don't know if it's possible to use the ABS sensors and such from the junk cars i can get with the hubs/spindles and axles from an SN95. I plan on ripping into some stuff this spring and see what i can figure out. What i'd mostly like to know is where the computer would generally reside. If it's part of the cars main computer then i'll say screw it. If there's an individual computer somewhere that controls the ABS then maybe it's not too difficult to swap the electronics over.
my thoughts exactly, if the computer is seperate, its a feasible task, it not then i wouldnt even attempt it, i just thought they'd be a nice feature to have
