auto sr20dets were rare and ud have to have the importers specially import it because most of them dont bother bringing over the autos.

the ka transmission works but you have to use the SR bellhousing and the KA gears are longer.

if ur looking for an automatic turbocharged car go ka-t with a good torque converter with a nice 3000rpm stall for some off the line spoolup. i wouldnt bother with trying to get an auto SR20.
