Building the roll cage for the ‘ghettocet’ is easily the most time-consuming part of this build. But here we are … finally … with a custom cage built and installed by yours truly. There are a few odds and ends to add, like window net mounts and a Lexan windshield. But for...
Last year, I converted the 1.6-liter NA Spec Miata to run in the Super Touring 6 class with NASA. This power-to-weight ratio class allowed me to shed the weight of the underpowered racecar aggressively. The result was a 2230-lb racecar with the driver, a reduction of 45 lbs. from the Spec Miata...
Let’s call this intermission on the Ghettocet Miata. A time to get up, stretch our legs, and see how far we have come. Frankly, I let my imagination run wild during the roll cage build, which has taken significantly longer than anticipated.
I wanted to simplify the intake path on the Miata as soon as I converted it to Super Touring 6. After fruitless research yielded conflicting results and very little non-anecdotal data, I decided to hack my own system together. The result is the shortest intake possible while retaining the factory...
It is finally here: the fabrication portion of the exo car build. Getting to this point has been quite the process: digging up all of my old equipment and piecing together a functional fabrication space. But with all of the prep work behind me, it is time to build the roll cage. The first step is...
Mechanical tube benders need to be mounted securely to the floor for operation. Typically, a hammer drill and concrete anchors are used to secure the mount to the floor. This time, though, with the JD2 bender being converted to hydraulic, I am free to mount the bender in a mobile configuration...
I have a bit more work to do before starting the roll cage on the exo car build. One of those tasks is converting my 15-plus-year-old mechanical tube bender to hydraulics. To risk sounding like a broken record, my workspace is small and not tube-bender-friendly. I can save space by converting the...
The old adage goes something like this: You can build your car fast, cheap, and reliable. Now, pick two. This principle seems to hold true with racecars and most things in life. But occasionally, a product comes along that seems to laugh in the face of this principle. I actually got excited when I...
The roll cage is a pivotal moment in the exo car build, and I am taking a super small step back to ensure the cage is executed properly. After all, it has been 10 years since I fabricated, installed, and welded a roll cage. Although I am still confident in my abilities, a few decisions and other...
In the previous Failure Points segment, I discussed a recent front wheel bearing failure on the Super Touring 6 Miata. This failure was abrupt, and there was no indication of issues before the session. And as promised, here are the steps to replace the front wheel bearings on the Miata. A...
The harsh environment of the racetrack pushes a car right to its limit and beyond. As such, racecar failures are bound to happen in many different ways. Failure Points is a new series that dissects these moments and what to do when things go wrong. This time it is the front wheel bearing of the...
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...
