Terrifying 2,200-Lb Miata Packs a Turbo LS V8 Making 550 WHPA 1992 Mazda Miata wearing a turbocharger intake where its left headlight used to be, a chassis-mounted wing large enough to dry laundry on (and yes, that actually happens in the video), and a license plate reading GOATKART. Welcome to one of the best series on TikTok.The social media series "Day 8 Of Riding In My Followers Cars Until I Get Scared" is a simple but brilliant idea: a host rides shotgun in increasingly unhinged machines belonging to his followers until something finally rattles him. The car that showed up for episode eight was a '92 NA Miata stripped down to what is essentially a rolling tubular frame – open-air, caged, drag-tired, and hiding a turbocharged 5.3-liter LS V8 under the hood. "Not only does this car look like it's straight out of Rocket League, but it weighs less than a Smart car and has more power than a G80 M3," the host announced before climbing in.The Numbers Behind the MadnessThe owner broke down what this thing actually is: "She's a '92 Miata with a turbo 5.3 LS, a ZF 5-speed out of a BMW M3. She gets down at 2,200 lbs, making around 550 wheel."AdvertisementAdvertisementThose figures deserve a moment. A factory NA Miata weighs between 2,094 and 2,183 pounds and draws power from a 1.6-liter four-cylinder engine rated at roughly 115 horsepower. This car weighs roughly the same – despite now containing a V8 – because there is barely any car left around it. The interior is gone, the bodywork is largely gone, and what remains is essentially a purpose-built drag kart wearing a Miata's identity as a technicality. The 2026 BMW M3 Competition's 523-horsepower crank output generally measures between 420 and 440 wheel horsepower when put on a dynamometer, according to available figures. The Miata claims 550 at the wheels. The math is not kind to the Bavarian.GM's LS V8 lineup has earned its reputation as the go-to choice for engine swaps among automotive enthusiasts, with its relatively small footprint and vast aftermarket ecosystem making it the dominant option. Wedging the 5.3-liter truck variant into an NA Miata and then turbocharging it takes that ethos to its logical extreme. According to TopMiata.com, most LS-swapped Miata projects cost anywhere from $25,000 to $50,000 based on how the car is built out – and by every measure, this particular example lands squarely at the top of that spectrum.An 8.1 and a Genuine YellBuckled into a red RaceQuip five-point harness with zero roof between him and the sky, the host counted down the launch in Japanese before the owner sent it. What followed was a V8 roar, a turbo spool, and the host screaming "I guess it's true, size does not matter!" into the open air.At the end of the pull, he delivered his verdict: "I'm gonna give it a scare score of an 8.1 out of 10. But guess what? I still need to go faster."AdvertisementAdvertisementThat's the thing about a car like this. An 8.1 from a guy who does this for sport is impressive. It also tells you there are people in his follower list driving something worse. The owner's closing line before the launch – "Yeah, let's see if we can get your smile to match the car's after this pull" – was accurate. It achieved it.The NA Miata was designed around equal front-to-rear weight distribution and a trim, light body that allowed even a modest engine output to feel more than adequate. Whoever built GOATKART took that same platform and turned it into something that probably shouldn't exist on public roads. It does, though. And it's scoring 8.1s.
