I am not going weed through all these posts, so here's the info:
ZX3: mid to high 16's
ZX3's lightly modded 16.3 was the lowest I have seen
SVT Focus:
I have seen these run anywhere from a 15.8 to a 16.3, nearly identical to the Civic Si.
I have seen these time posted many times at both Sac and Sears. These motors are kind of torquey, so they do feel quicker, there 60ft times are decent but they die in the highend, which is probably why Fuji was able to walk on him in a Civic.
My friend had one, put a turbo on it, and it burned to the ground

They handle great, and it's a good car (despite it being a Ford) for the money.
