Will a rx-7 even run if theres zero compression in both rotors at all and will it even idle for a second if theres zero compression in the rotor.can anyone get back to me and let me know also if its possible for both rotor apex to wear down in the same day?

 

run? maybe, but probably not well. assuming you mean zero compression on a face, not all three, especially not all three on both rotors.
word your question a little better. "both rotor apex to wear down in the same day" ?? there's 6 apexi (apexes?).
if you lose an apex or corner seal, thats compression on 2 faces.
side seal would be one face and it also depends what the seals take out with them.
