This is a 1999 Mazda Miata with a Hellcat’s engine. Take a few moments to drink it all in.
And yet, YouTuber KARR decided to get a 1999 Mazda Miata, throw away it’s 1.8-L 4-cylinder engine (with 140 hp, in case you were wondering), and give it a bit of an upgrade. And by a bit, we mean something like 600 more horsepower.
Obviously, the process of shoe-horning a 6.2-L supercharged V8 in place of a teeny tiny Japanese four-banger required some sacrifices. Namely, the hood. As you can see, the engine block and supercharge now sit squarely above the metal, meaning this car isn’t exactly all-weather capable anymore. It also completely ruins the weight distribution, although suddenly making this Miata extremely front-heavy makes it an ideal platform for donuts.
As for the rest, KARR did the best he could. An anti-roll bar, new Wilwood brakes, and fat Hoosier R7 racing tires try to give the Miata a semblance of control, while a welded Ford-sourced 8.8-inch rear diff takes the Hellcat's punishment without flinching. The interior has been ripped out and replaced with a set of Sparco racing seats and a roll cage, while the exhaust has been removed so it just pumps gases out the front.
To make it remotely usable on the road, VMP Performance gave the Miata two engine modes. Regular mode cuts the engine's power down to somewhere around 400 horses so that a mere tap on the gas doesn't send this car flying off a cliff, while "race" mode unleashes all 683 horsepower.
That's rear-wheel horsepower, by the way. In case you were worried this Miata somehow had less power than a regular Hellcat.
According to KARR, this thing can hit 175 mph in fifth gear. We’ve got no idea what it can do in 6th gear--presumably, it’ll actually take flight.
Best of all, you can buy this car if you really like it. It’ll be on the auction block at Barrett-Jackson in Las Vegas from October 3rd to October 5th. There’s no reserve price, which means whatever people bid is how much it’ll sell for. A Miata in good condition might go a few dozen grand, but this thing? No clue.
