Way too much. It is less to build the auto (less as in less costs, less time, less of a pita) to the point where it shifts quicker than a manual. Unless you are building your car up and/or plan to race primarily for the drag, a built auto is not worth it. If you want manual for enjoyment, trade a buy. In the long run, you will save. Also, getting the tranny swapped will be a warranty voider all around, even if you use Nissan parts. (Or at least that's what a few dealers have told me
)
