WOW just WOW. Don't let all your little car buddies try to explain what an rx-7 has.

And by the way all 86-91 Turbo II Rx-7. All had 550cc top feed injectors. The only Rx-7 with side feed injectors are 93-95 and guess what their still 550cc and that was only the primary injectors. The secondaries were still top feed. Mazda did this because it was more a space issue than a performance issue.
