don't be so quick to make judgement about cars without considering the whole picture:
alot of times, driver makes a WHOLE lot of difference, and keep in mind most SR20s in the states are from wrecked cars from Japan that's been sitting there who knows for how long.
NA 240s aren't necessarily boats, it depends alot on the driver. Usually the consensus on stock manuals is very high 15s and 16 flats. But I've seen stock cars run mid 15s (of course, good driver).
The thing about the KA24DE motor is it runs out of breath very early in the RPMs, you you have to shift early (depending on gear), alot of ppl do not know this and ignore this. The S14's power starts to drop about 5500+ (redline of 6500). and When I say drop, I mean obscenely drop.
