any RB26 up through 94 has (or could have ) the faulty collar. Jun makes a new collar for $120ish.

Like RBMonster said, the crank collar issue can occur on R32 or R33 motors. It just depends. There is no way to look at the motor and tell if you will have the issue or not. The only way to find out is to remove the oil pump and take a look at the snout of the crankshaft itself.

Also, that JUN collar is not a simple bolt on solution. If you choose to fix the issue, you will basically be rebuilding the bottom end.
