can anyone tell me what injector(s) feed the rear rotor of a 86' n/a RX-7
thankz

 

not to sure about your question,,,, injector SIZE or injector location?

The rear roto is fed by the primary injector near the firewall and the secondary injector nearest the firewall.

there are two sets of injectors... The primary set is actually set into the center iron housing of the motor (you have to take the intake off to see them on an N/A) The secondary set is located on the Intake manifold, those are fairly easy to get at.
