The 1991 Mazda Miata from which I am building the exo car has led a rough life. This was especially evident when I finished the chassis cleaning in part 5; quite a bit of surface rust was exposed. Usually, I would wait to address the rust during the fabrication process while fitting the roll cage...
Didn’t I mention this may get a little confusing? In part 4, I cleaned up the chassis, removing any remnants attached to the car, cleaning up the cuts, and grinding a few miscellaneous brackets off. Now, I am physically cleaning the chassis to prepare for the final prep and welding. Taking...
The “ghettocet” project keeps growing. That’s not a bad thing but I have quickly realized that a project of this scale is going to take a bit more prep and cleanup than usual before I move on to the roll cage.
I decided to go ahead and remove the subframe from the chassis. This is a pretty straight forward process in the Miata and will give me easier access to everything when I finish the chassis prep and install the roll cage. However, due to my limited work area, I did have to get a little creative.
Exo cars come in all shapes and sizes. This one is an extreme example of what is possible on a limited budget. As such, in part 2, it’s time to get out the cutting tools and get the car chassis down to as low a weight as possible.
In part 1 of the exo car build guide, I disassemble anything that bolts to the Miata. This would be the interior, dash, seats, doors, soft top, and trunk along with anything else that removes semi easily. And where last time I said, ‘this is going to be a lot of fun.’ This time I...
I love junkyard builds and I have always subscribed to the do more with less methodology. So building an exo car is something I have wanted to do for a very long time. It’s also an excuse for me to brush up on some old skills and hone some new ones.
One of the things I have enjoyed about my foray into Super Touring racing with NASA is the open rule book. Building a car to a power to weight instead of the strict rules that go along with Spec racing. This has opened up many engineering possibilities and things I would like to try. One of those...
The little 1.6-liter engine in the NA6 Miata moves too much. This engine movement, combined with soft factory differential bushings, contributes to a lot of drivetrain movement.
The now ST6 Miata has had some serious electrical gremlins from day one. Intermittent starting issues, random fuel cuts, and erratic idling to name a few. I knew at some point I would rewire the car completely. What I didn’t anticipate however, is that I would give the rewire a first pass...
I spoke about this before in Trying Not to Finish Last at NCM. Although the budget Spec Miata is a blast to drive, it will never be competitive when the expensive equipment comes out to play. That is why I have decided to move the car to Super Touring 6 (ST6). The move to ST6 will open up the rule...
And why I need to implement them now. In past seasons, races in the rain were rare, with only a few to suffer through. But lately, it seems like every race weekend has weather looming over it. Half the races this season have been in what I like to call dynamic conditions. And with these dynamic...
