I understand that Third Generation RX-7 Mazda Rotary engines (93-95)

use the

electronic metering pump, which is controlled by the computer that runs the
engine.  If the original engine computer is removed, and an aftermarket
ignition and fuel control system is used, like the one supplied by Tracy
Crook, which one of these pumps is the correct one to use for the Third
Generation block, and what would be the mechanism to properly meter it?

Good question. From the looks of it the earlier mechanical pumps won't fit.
Mix the two cycle oil with the gas. One ounce per gallon.

longer (less carbon build up).
Maybe someone will do the circuits one day to adapt the electronic metering
unit to a manual controller. It might be a project for
someone............with an oscilloscope and lots of time on his/her hands.
