Perk up your Mazda Miata with BBR's new 248-horsepower turbo kit

For three decades, enthusiasts have argued whether the Mazda MX-5 Miata needs more power. For its part, Mazda seems fine with leaving the Miata as is, even reducing the horsepower from the third- to fourth-generation models, though the car lost a little weight. That's where tuners like BBR in the UK and Flyin' Miata here in the US step in, offering aftermarket solutions for those that crave a little more grunt. BBR announced today that its new 248-horsepower Stage 1 turbo kit is ready and waiting for the new 2.0-liter-powered ND Miatas, including the new Miata RF. BBR's first Miata turbo kit was released all the way back in 1990. Since then, the shop has been tuning and honing its craft, releasing ever-more potent variations its comprehensive power kit. This new version, like the previous ones, focuses not only on adding more power but maintaining the level of drivability and refinement you expect from all Miatas. The Mazda electronic safety features are retained, and the team is working on CARB emissions approval. That said, with BBR tune an ND Miata will hit 60 mph in just 5.0 seconds, roughly two seconds quicker than stock. To get the peak 248 horsepower and 236 lb-ft of torque, BBR does more than simply slap on a big turbo. In 2014, BBR began using a Mazda3 as a development vehicle in preparation for the new Miata's launch. A twin-scroll turbocharger is mounted onto a custom cast-iron manifold. A front-mounted aluminum intercooler keep things cool and doesn't require cutting up the bodywork. The engine breathes in through a K&N air filter and exhales through a stainless steel downpipe. The whole thing is controlled by BBR's Starchip / EcuTek RaceRom ECU software package. Other upgrades include silicone turbo pipes, an aluminum battery tray, a recirculating piston type dump valve, a carbon-fiber heat shield, and stainless steel oil and water lines. BBR is offering extended warranties from 12 to 36 months. In the US, the sole distributor is Flyin' Miata in Colorado. At $5,695, it's not a cheap proposition, but it is less expensive than one of Flyin' Miata's V8 swap kits. Less expensive (and less potent) performance kits are also available.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.

Mazda could electrify the next Miata, is trying to figure out how

The next Mazda Miata is at the embryonic stage of development. The men and women in charge of the project are debating whether to electrify the roadster, or if it's better to keep it true to its roots. The Miata is not a high-volume model in any market, so it doesn't need a plug to help Mazda comply with looming emissions regulations. The company explained it's not a matter of compliance; it's about how the definition of a sports car and the expectations of motorists could change in the 2020s. "The preferences of people who enjoy driving sports cars might be changing, so we need to think about what direction society is going in. We want to look at the best powertrain to keep the vehicle lightweight, but because of the diversifying requirements and preferences, we need to explore various options," Ikuo Maeda, Mazda's global design director, in an interview with Autocar. Adding any degree of electrification to the Miata beyond a relatively basic mild-hybrid system is easier said than done. An unusually low weight and a compact footprint defined the original model introduced in 1989, and these attributes continue to characterize the fourth-generation car (pictured) sold in 2019. Electrification requires batteries, batteries add weight and require space, and Mazda doesn't want to end up with a 3,000-pound Miata, or one that's the size of a Mercedes-Benz S-Class Convertible. Keeping its chassis balanced is a delicate task, too. Overcoming this challenge is not impossible, however, and batteries are expected to become lighter and smaller during the 2020s. The next-generation Miata isn't expected out until the middle of the 2020s, so Mazda has time to figure out whether it should go hybrid, arrive as an electric car, or carry on with a rev-happy, naturally-aspirated four-cylinder engine. Maeda stressed a final decision on the matter hasn't been made yet. "I don't have the answer right now, but we need to make a vehicle that people can own without worrying that they are not being eco-friendly," he concluded.
