Getting back to the original topic.... any auto tranny is going to be a poor match to a B18C1's powerband.

And there were no GSR's made with auto transmissions for the US market.

I'd look into headwork and cams for her stock motor first. Or even a Jackson Racing SuperCharger. What you'll need to make an AT-equipped car move is a healthy amount of torque down low....and for that, the JRSC is probably your best bet.

If she's truly interested in performance though, she really ought to get over her phobia of manual transmissions.
