mazda suggests minimum 91 octane for turbo rx7s. running 87 isn't going to blow your motor but you increasing your chances. plus 91 has lower EGT's.

lot of the track guys run 50cc pre turbo and 250cc at the throttle body. or 50cc pre turbo 150 after the IC and 150cc at the throttle body.

^ When did Mazda suggest running 91 vs. 87? I thought they were designed to run on 87.
