whats the difference between the civic engine vs integra engine?

Question

V-Tec non v-tec DOC VS SOC

Answer 1

Civics do not have v-tec engines. V-Tec engines have variable valve timing, meaning as the rpms go up, the engine changes when the valves open to allow better breathing. This is like a kick in the pants but only works at higher rpms.

Answer 2

about the same difference between cow crap and horse crap.
