difference between 2006 honda civic ex and si?

Different engine.The ex came with a 1.8ltr vtec, and the Si with the awesome 2.0ltr k20 i-vtec. On the Si the suspension is different( More sport tuned), and the trans had a limited slip differential. Not to mention the 6speed manual. Basically the Si was made for performance as the EX was for fuel economy, and basic transportation.
