1993 Mazda Rx7 - Rotary Engine Rebuild - Parts List

Intro - Part 1 - Part 2 - Part 3 - Part 4 - Parts List - Final

Below I have listed practically every part I had ordered for the rebuild of my 13B engine as well as any additional parts that were upgraded/replaced as well. All of the "xxxx-xx-xxx" part numbers towards the top are Mazda specific part numbers which can of course be found at your local dealership or online if you take the time to look. Minus the extras listed at the bottom (transmission, radiator, vacuum line, motor mounts, oil pan brace, etc.), the engine rebuild alone cost around $2,000. Since I did the job myself and saved on labor costs, I was able to put that savings back into the car with reliability mods/upgrades as well as replace additional items like brittle coolant/air hoses, gaskets, oil injector lines, etc. These items are typically overlooked when doing just a core rebuild however I can be certain that if a part was bad or had potential for failure, then it was replaced.
