Hi All, I just bought a Honda Civic SI '97, and I'm having a hard time finding any info on the car motor and MPG, what is the difference between the Civic SI and EX? I was told they are similar but the SI has more features.
Any info is good.

 

The si is the american version of your sir (in canada im guessing). so you have our ex

 

That is what I was thinking too. The Si trim wasn't available in the US from 96-98 and 01-03.
