Could someone please help me with what year and make rx-7's come with 660cc and 720cc low impedence injectors. A factory mazda number and casting number off the injector would greatly be appreciated. Is there anyone who may know the authentic japanese part numbers as well.

Thanks guys.

 

The '84-'85 GSL-SE came with the 660cc (I thought it was a slightly different number but in the 600's somewhere). I have heard someone say that the '85 GSL-SE had the 720s with the '84 having the 660's although I believe this to be wrong. The Japanese turbo 12A first gen. engines had the 720's. I don't know of any part numbers althought the tops are color coded to their size. I'm sure someone here can add their insight on this. I believe the 720s were green on top. I could be wrong but I'm sure someone will correct me if I am.
