other than compression and maybe weight. Are there any differences between these rotors?? Seals, Bearings, etc.

mazdatrix states that the 86 - 88 NA rotors have a CR of 9.4. and the 89 and up TII rotors 9.0. How much of a difference would that .4 make if using Turbo rotors in a NA application??

Yea I second that. No weight difference in the rotors from a NA or turbo charged rx7.

s4 and s5 rotors do weight differently, s5 weighs a little less but with higher compression. YOu can use either as long as you use the right conterweights.
