haha, I have an EX. First off, as 98 EX RED said, if you have an EX, it has a 1.6 VTEC motor.

You cant make a car into an Si..... So in other words, if you want what the Si has, Swap in a B16, new suspension setup, get some good swaybars, loose a few LBS (you and the car..). And call it a day, you still wont have an Si, so dont call it an Si unless you got it from honda that way.

People are stupid to do things like swaping the badge from one car to another, unless your going from Si to a lower model badge to make a sleeper ;-)...
