Joe,
  Actually the 86 to early 89 were the same then 89 to 95 we= re for the same weight
rotors (last year the 3rd generation RX7 was imported to the US a= lthough it was produced in Japan until about 2002).
 
 The way to tell if a 89 engine is early or late production is to= check the combustion
dish (depression) of the rotor.........If it is rough (as cast) u= ses the 86 to early 89 counterweight.
 
 If the the combustion dish is smooth (machined) it is a lat= e 89 to 95 rotor and uses
89 to 95 counterweight.
 
 The Renesis rotors are a different weight and uses the appr= opriate counterweight. 
 
 Also the compression ratio of a given year model rotor makes no = difference as the
NA or Turbo rotors are the same weight.
 
Hope this helps,
