My friend from hs has 3 probes (well each of his brothers have one a piece) Two of them are GT's. His brother ran a 16.1 at the track and it has next to everything done to it, NA of course and no NOS. Greddy exaust, headers, superchip, ssr wheels, intake, ported and polished intake manifold, full suspension, some fancy computer, and a bunch of other stuff i don't remember, and yeah he only ran a 16.1 with a 93 GT. My friends is a 94 and he has exaust, intake, better cams, i might be forgetting some things, but he was always like a car or so behind his brother when they would race. I"m not sure why i never raced him, we always talk about going to the track but never do. He's got great low end but after second gear there isn't much. A csvt should take a probe gt if it doesn't have the jap engine in it, that is assuming that the race is long enough for the csvt to pull away with its top end....
