I recently picked up a mint condition 91 maxima with an automatic transmission(blown). I figured I would just buy one at the boneyard, but 1000 dollars for a used one sounds a little rediculous. My question is would it be possible to convert to a 5-speed, or will that require computer mods for the fuel injection? I have converted an s-10 to a v-8 with a new style vette rearend so the mechanical/machining work is not a problem, however the computer aspect is not quite my forte. Any comments would be greatly appreciated.
