Anybody has numbers of the difference in 0-60 times between an Automatic with Superchip and a Manual with Superchip?

I use to drive a Mazda with manual 2 years ago but when I was shopping for my Contour I was too anxious to get it so I ended up with an automatic. I'm getting ready for some serious upgrades but I don't want to do these mod if I'll be loosing major because of my 4 speed AUTO!!! I'd be better trading my Contour for another 5 speed Contour.

In the worst case, anybody know if changing the transmission to a 5 speed manual is possible?
If so, how much?

BTW, thanks guys since all your suggestions are very interesting! I'M JUST SO CURIOUS AND IT KILLS ME confused
