stock on a brand new motor would be low 14's....but typically a used stock ds will run between 14.5-15.0. Although they are really cheap to mod and easy to make go faster. 13's should be no problem, 12's will most likely require some slicks or draf radials on a FWD. check this page out I know it says it's for 2gs but all the mods on the page will work on your car as well. I think RRE (road race engeineering) has a write up like this one for 1g.
