I want to make something clear for the uninitiated: Mazda never put a 3-rotor engine into an RX-3. Not for production, not for racing, not for anything. And that seems– well, just wrong! Luckily, the guys at DNA Garage agreed, and decided make things right by building the one-off, 400HP Mazda RX-3 you see here.
Displacing nearly 2 liters and fitted with a pair of sequentially arranged, intercooled turbos, electronically controlled fuel injection, and twin-spark ignition, the Mazda 20B three-rotor engine was already capable of 300HP and 297TQ when it debuted under the hood of the Mazda Eunos Cosmo in 1990. With a bit of tweaking (and a massive disregard for government emission laws, I imagine), the 20B fitted to this little Mazda is making almost 400HP … more than enough, in other words, to put the fear of
God Felix Wankel into the hearts of the Corvette and Porsche guys at your local trackday.
