if you have an auto tranny built right. and im talking totally rebuilt auto ECU, torque converter and the actual tranny itself, then the auto will definetly be faster than a stick. a computer can always shift faster than a human can, and with proper tuning, it can shift at the same RPM every time as well. unless your turning your car into a strict performing beast though, i would go with a manual. it will be more fun to drive, hold more power with less problems, easier to do burnouts, better for drifting, the BOV is usually a lot stronger sounding, etc. i enjoy driving manuals as long as its not in traffic, they always feel like they are more powerful.
