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.

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.

A lot of people use gasket sealant around the outside of the motor housing water jacket. I however, opted not to gum up the entire motor with sealant as it is completely unnecessary. If you take your time cleaning your housings and verifying that they…
