The 13B-RE from the JC Cosmo series was a similar motor to the 13BREW but had a few key difference's namely it being endowed with the largest side ports of any later model rotary engine.

Compared to the twin turbos fitted to the 13B-REW on the FD RX-7, these sequential turbos received a large (HT-15) primary with a smaller (HT-10) secondary turbo. Injector sizes = 550cc PRI + SEC.

Approximately 5000 13B-RE optioned JC Cosmos were sold making this engine almost as hard to source as its rarer 20B-REW big-brother.[citation needed].

1990–1995 Eunos Cosmo, 235 hp (176 kW; 238 PS)

13B-REW[edit source]

A twin-turbocharged version of the 13B, the 13B-REW, became famous for its high output and low weight[citation needed]. The twin Hitachi HT-12 turbos were operated sequentially, with the primary providing boost until 4,500 rpm, and the secondary coming online afterwards. Notably, this was the world's first volume-production sequential twin turbocharger system. [4] Output eventually reached, and may have exceeded[citation needed], Japan's unofficial maximum of 280 DIN hp (206 kW) for the final revision used in the series 8 Mazda RX-7.

1992–1995 Mazda RX-7, 255 hp (190 kW)
1996–1998 Mazda RX-7, 265 hp (197 kW)
1999–2002 Mazda RX-7, 280 hp (206 kW)
