My friend has a '99 Z24 ATX, and we did a "fake race" from a light (fake as in up to about 30 feet , that's when the lanes converged and I gave in behind him). He was directly ahead/diagonal when I slowed down and we merged. The Z24 does okay, but considering that my 'tour doesn't have very good pull until about 2nd or 3rd gear (from 30-34 mph onward), I had two more people than he (four as opposed to two), and the extra rear weight contributed to some tire slip on road sand, I believe that I could have had him if we went alone together at a track.
It's a good car, and for 150 horsepower, that 4-banger can go. But faster than an SVT? I seriously doubt it.
