I got some info and I'm pretty sure now that canadian civic DO NOT have any 70hp motor (D15B8) so any civic come at least with a D15B7. The oly difference between CX and DX is the interior package. The same goes for the LX and EX. The only EX thats had VTEC was the EX-V and was produced only one year, but I don't know which exactly.
Though, I see only one explanation for my friend going faster than me in his EX and me in my CX. He is a better driver than me. Cause I'm supposed to be way lighter than him and having the same motor. I think that probably summed it all. Maybe I was afraid to face it, he drives better than me !!!!
Horn out.
