* 1987-1989 (and some 1990) 2.2L Turbo I4: This engine's quarter-mile time varied depending on condition, driver skill, altitude, and even tire condition. A *reasonably well-maintained* example might run in the high 15s to low 16-second range. However, some sources claim times as low as the mid-15s, while others report slower times in the 17-second range.
* 1990-1994 2.5L Turbo I4: This larger engine usually resulted in slightly quicker times, although the difference wasn't dramatic. Expect a range similar to the 2.2L, but potentially a little faster, possibly in the mid- to high 15-second range, again heavily dependent on the factors listed above.
In short: You can't give a precise number. Think of it as a range, typically in the high 15s to low 16s for both engines, with variations above and below possible. Magazine tests at the time would have provided more precise numbers under controlled conditions, but those results would still only apply to the specific car tested.
