I'm not sure what 2.3 liter dohc motor a cavalier would have.
In 95' there was a 2.4 dohc motor related to the quad 4, and a 2.2l ohv motor that was shared with the s-10.
If you have a V6 ATX, the 2.4 is close, and will likely be faster with a 5-speed.
A 2.4 MTX Sunfire 2dr was about even though just a hair faster than my duratec mtx contour.
