my bone stock '92 ran a best of 15.5, never had a 16 second run unless i had a noob moment and missed a shift or something.
my old '90 with a twin cam swap and an intake was a bit faster than that, though i never had it at the track… i just know that because it pulled harder on friend’s cars… the motor even had 270,000km on it.
maybe i should have said S13s with owners that make sure they run right run 15’s all day.
regardless of what anyone says, from my experience any S13 that ran properly ran 15’s.
