The only turbocharged Mazda Miata that has made production is the second generation Mazdaspeed built for the 2004 and 2005 model years. Mazdaspeed equipped the Miata’s 1.8-liter engine with an IHI turbocharger creating 8.5 psi of pressure that pushed the engine to develop 178 hp and 166 lb-ft of torque. The Mazdaspeed Miata wasn’t just about extra power, though. The little unicorn also came with tuned Bilstein suspension, upgraded six-speed manual transmission, 17-inch Racing Hart wheels, and unique interior trim.
The best total build estimate is 6,235 units with its rarity depending on the market. The Mazdaspeed Miata was available in Japan (300), Canada (353), New Zealand (15), and the US got 4,000 models. A fire at the production facility meant that Mazda built less than intended in 2005 for export. For that year, the US only got 1,428 units, Canada got 53, Australia received 174, while New Zealand got just six.
