Im a little confused, Im looking for a set of low compresion rotors and need some help. This is what i found out so far. 87-88 turbo rotors are 11lbs 8.4 comp, 89-91 are lighter(but I dont how much lighter) I also dont know the comp on the 89-91 rotors.



Thanks in advance

 

They are actually 8.5:1, and Mazdatrix has a handy chart for this...
