I’m doing what I can to catch up to the present day. The Miata’s conversion from automatic transmission to manual took place over a few weekends in July of 2013. This was a big project. I spent the winter and spring earlier in the year researching the process, pouring over the Mazda parts manuals, and ordering parts. It sounds tedious and boring, but I actually enjoyed it. If I could do things like this for a living, I would be a happier person.

Here’s the 5-speed I picked up locally. Thank you, Craigslist.

The car spent two weekends airborne.

Out with the auto. We strapped the transmission to a jack and lowered it out of the car. It’s a beast. The manual is considerably lighter.

A good friend of mine was able to help with the install. He has a knack for all things mechanical. As a result of his help, the work was much quicker and far fewer curse words were spoken.

New clutch in place. I went with an Exedy Stage 1 race clutch and a lighter flywheel of the same brand.

This was not an uncommon sight.

It was fun to figure out how to wire a few things so that things worked in the end. The ECU is still the auto version. We’re basically telling the car that it’s in park by jumping these pins. With the car “in park” the ECU will allow the engine to be started. You could run wires from the pins to a clutch switch and it would only start with the clutch pushed in. Nah…
