I got this off the Honda Civic Forums:

You'll need to click on the "Watch the Movie" link to the right side of the screen. It gives an good description of the technological featues of the new 1.8L engine in the current Civics. Be advised though, it's slower than a seven year itch to load. Once it's loaded, the movie plays normally.

You can click the links on the left side of the screen for DOHC VTEC, SOHC VTEC, SOHC VTEC-E, and 3-stage VTEC. It's pretty cool!
Hope this helps,
