4cyl are pretty much one of the biggest advances in engine, honda has mastered them. Does it matter if it was an ex, dx, or si, definitly, don't also forget that ricers often go to an autoparts store and buy the emblems!!!...that's like us owning a 5.2 and putting a 5.9L emblem on. People who mod civics properly, know what ther are doing, and it's always gonna come down to power to weight ratio. The only time i race civics, or other ricers are when they come after me. Ex: driving through tim hortons needed to merge quickly so my exaust was quite loud, some guy in his modded ricer decided to come after me, and try to take a kill...lit his tires first light, same with the second, on the third he was getting pissed at me. So i put my coffee down, and brake stand the truck, his face was priceless...needless to say light went green, he saw my ass end and turn off before the next light couldn't even face me like a man and honor the loss. (that's what I hate about ricers). On the other i had my ass handed to me by a civic, mind you it had a complete engine swap, cam, ecu, IHE, the whole thing was done, only thing he didn't have was a power adder. and he came hunting again, so i strap up, knowing he's going to win, his car that weighs less then my truck, with the same power output, story short, truck saw his back end, i took him from 1st, to 3rd though, gotta love torque, but his gears redline at 8000. compared to our 4700 so he got me on the long run, what did i do, stop and look, and talk. what's with his car know???...he ditched it doing 170kmh, cars, written and he just got released from hosiptal!...ok i'm done, sorry vetning
