A lot depends on driver so its hard to pin an exact time on a car. Do some research, but to help you out.
RX-8 14.5-14.8, I've seen times as bad as in the 15s.
RX-7(which year, im assuming 92+) 13.8-14.2
Celica GTS 14.8-15.2, I've seen as bad as high 15s
Celica GT 15.8-16.2, I've seen as bad as high 16s
Mx-6 I have no clue
Evo 8 13.4-13.8
Evo MR I dunno, probably only slightly faster, id guess 13.2-13.5
