Kelly and All,
Even when the weight of the rotors and = the counter=20 weight are confirmed as being compatible - one should also remember=20 the lettering stamping system which matches a paired set, for = balancing=20 through similar weight. I have never been able to confirm what the = difference in=20 weight is exactly, which is a shame.

  Joe,
    One other consideration........I have presumed = your 89=20 13B was a NA (6 port) 
and not a Turbo (4 port) engine........Although the NA and = Turbo=20 rotors are the
same weight the Turbo rotors are 9.0 to1 comp. ratio.........(the = end I=20 hope)

    Yes the 3rd gen counterweight will = work.......Just=20 make sure that that your 89 rotors

.........Bulent used a 13B Cosmo flexplate (it is like the 3rd=20 gen) but he used the Cosmo

Joe,
  Forgot to add this.........It depends on the year = model 13B=20 also........The 86 to 88.5
2nd gen had heavier rotors and what I reported is = true.........The=20 88.5 to 91 2nd gen
13B have rotors the same weight as the 3rd gen and should = be able=20 to use the 3rd

Joe,
   A 3rd gen counterweight and flex plate will = fit 2nd=20 gen 13B but the counterweight
will put the 2nd gen out of balance unless rotors and = both=20 counterweights  from the
