How much horsepower does a stock Mazda RX-7 FD have?

The horsepower of a stock 3rd-generation Mazda RX-7 (FD) depends on the market and the specific model year:

US-Spec Models All US-market FDs (1993–1995) were factory-rated at 255 horsepower at the flywheel. When put on a dyno, a healthy, bone-stock US-spec car typically puts down about 220 to 235 horsepower to the rear wheels ².

Japanese-Spec (JDM) Models Models sold in Japan came with higher ratings due to less stringent emissions laws (allowing for less restrictive factory downpipes) as well as continuous engine and turbo refinements over the generation's lifespan:

• 1992–1995: Rated at 255 PS.
• 1996–1998: Rated at 265 PS.
• 1999+: Rated at 265 PS to 280 PS. The 280 PS rating was reserved for higher-tier or limited-edition models (such as the RS and RZ) that featured better turbos and slightly more boost ².

Note: The "280 PS" (276 hp) figure on the later Japanese models was dictated by a legal agreement restricting manufacturers from advertising numbers higher than 276 hp. In reality, actual engine output on those higher-trim models often exceeded the advertised numbers ².
