Zc ?

when driving home from work to night i saw what looked to be a POS hatch back smoke this nice looking acura. i sped up to see what was going on. i cought up to the acure real easy( it was slow any way like all acura's but it still looked nice) eventually the acura turned off , as it was put to shame. when i cought up to the old hatch back i said, " dam that thing is quick. what you got under the hood" alls he said was, "ZC"(I think) what the hell is a "ZC" it was real noizy to, but it didn't sound anything like a turbo. alls i knew was i wasnt even going to try to race that thing. he may have even had nos in it to . that old beat up hatch back was a sleeper though
