The MazdaSpeed Miata is notable for its rarity. Produced only between 2004 and 2005, Mazda made just 5,500 of these turbocharged Miatas, making them a collector’s item today.

Under the hood, the MazdaSpeed Miata sports a 1.8-liter DOHC 4-cylinder engine with an iron block, similar to the standard model but with significant upgrades to handle boost. Lower compression pistons and slightly stronger rods make the engine more robust. The car is fitted with an IHI turbocharger that delivers 8.5 psi of boost, raising the output to 178 hp and 166 lb-ft of torque. significant improvements over the standard Miata’s 142 hp. This power boost transforms the driving experience without overwhelming the Miata’s lightweight character.
Performance-wise, the MazdaSpeed Miata can go from 0-60 mph in about 6.1 seconds. Its curb weight is around 2,469 lbs (1,120 kg), slightly heavier than the naturally aspirated Miata due to added components like the turbocharger and intercooler, which contribute to stability at higher speeds. Paired with a six-speed manual transmission and a limited-slip differential, the MazdaSpeed Miata is tuned for spirited driving.
One of the standout features of the MazdaSpeed Miata is its handling. Factory-fitted with Bilstein shocks and lowered springs, the MazdaSpeed Miata offers a firmer, more responsive ride. Mazda also added additional chassis bracing and stiffer roll bars, which reduce body flex and provide a stable, planted feel when cornering. These suspension upgrades make a noticeable difference, making the MazdaSpeed Miata feel more refined and connected on the road compared to the standard model.
The steering and clutch are also upgraded to handle the added power of the turbo. The MazdaSpeed’s revised steering rack offers quicker response, giving the car a sharper, more agile feel. The clutch is reinforced to handle the extra torque, and Mazda even modified fourth gear for smoother power delivery.
Inside, the MazdaSpeed Miata receives a few unique touches, including specially designed seats and a unique shift knob that adds to its sporty feel. Externally, it’s easy to spot thanks to a distinct body kit, custom front and rear bumpers, and a rear spoiler. The 17-inch Racing Hart wheels give it a unique visual flair, although opinions vary on their aesthetic appeal.
The MazdaSpeed Miata has a lot going for it, especially in the eyes of driving enthusiasts. Its metallic paint options, particularly Velocity Red, enhance its curb appeal, making it a head-turner on the road. Thanks to its sharp handling, this model has earned a reputation for delivering a dynamic driving experience. The stiff suspension setup, quick steering, and almost zero body roll make it a thrill to drive on twisty roads. Its turbocharged engine adds a punchy boost of torque, lending a lively, energetic feel to every drive, even though the turbo delivery can feel slightly unpredictable at times.
The MazdaSpeed Miata is also appealing for its analog feel, which is increasingly rare in modern sports cars. With hydraulic steering and no traction control, it provides an unfiltered driving experience that harks back to classic sports cars. Its 4.1 rear differential ratio and short gearing give a sporty, engaging feel, although this does mean frequent shifts, which some might find tiring for daily driving.
Despite its positives, the MazdaSpeed Miata has a few quirks. The short gears, while fun on twisty roads, can feel like too much work in city traffic. Turbo lag is also present, especially at lower RPMs, which can make the car feel less responsive at times. The interior is cozy but may feel cramped for taller drivers, and the high seating position can be a drawback. Additionally, like many older Japanese cars, build quality shows its age with rattles and an unrefined cabin feel.
Choosing between buying a MazdaSpeed Miata and boosting a standard Miata largely comes down to cost, availability, and preference. Due to their rarity and factory-built turbo setup, MazdaSpeed Miatas tend to command higher prices than standard models. Boosting a standard Miata, however, is often more affordable and can be done with a quality turbo kit from companies like Flyin’ Miata, which start around $3,000.
Boosting a standard Miata allows for more customization, giving buyers the option to handpick components like brakes, suspension, and even body modifications. A MazdaSpeed Miata offers a well-rounded factory-tested setup, while a DIY turbo build opens up more performance potential but may require regular maintenance. Weighing the factory reliability of the MazdaSpeed Miata against the customizability of a boosted standard Miata is key to making the right choice.
No car is perfect, and the MazdaSpeed Miata is no exception. One common issue is known as the “bog,” which is caused by a failing MAP solenoid and leads to stuttering or power loss, particularly after long drives. Rust is another concern, especially around the wheel arches and rocker panels, which can be expensive to repair. The fuel pump is also known to fail, causing erratic running or no start; many owners opt to replace it with a Walbro aftermarket pump. Transmission grinds, due to worn-out bushings, are another frequent issue that can be addressed with a shifter rebuild kit. The OEM Part Number of this solenoid is BP4Y-18-741.
For those looking to enhance their MazdaSpeed Miata, there are plenty of modification options available. Swapping the 4.1 rear differential with a 3.9 or 3.63 is a popular choice to make shifting less frequent and improve drivability. Adding bucket seats and a roll bar can increase safety and give the car a more race-inspired feel.
ECU upgrades are essential if you’re aiming for more power and precise tuning, as the stock ECU offers limited options. Many opt for a standalone ECU like MegaSquirt or Hydra Nemesis. A high-flow intake and exhaust system, along with a larger intercooler, can bring power up to around 200 horsepower, while a boost controller allows fine-tuning of turbo boost levels. For higher power goals, upgrading the turbo and fuel system components is recommended.
The MazdaSpeed Miata offers a unique blend of turbocharged power, responsive handling, and a raw, analog driving experience that makes it a standout choice for driving enthusiasts. While it may not deliver extreme horsepower, the MazdaSpeed Miata balances power with agility in a way that keeps driving fun and engaging. Its limited production and factory turbo setup make it a rare find that appeals to collectors and drivers alike. Ultimately, whether you decide on a MazdaSpeed Miata or opt for a boosted standard Miata, you’re choosing a car that embodies the spirit of driving pleasure, crafted for those who value the thrill of a truly connected, rewarding ride.
