the time that surprises me is the VTEC integra, i had a friend who use to own one and he always said it was sooo slow.
they are spose to be a luxury sports car, so 15.1 is alright for a 4cyl N/A car.
also the old turbo mx6 is quicker than the newer V6 model. ur spose to expect a mid to hi 15 1/4 in the old 1990 2.2 turbo models.
