JDM Mazda RX-7 FD 13B-REW Engine

A used JDM Mazda RX-7 13B-REW engine out of a third-generation (FD) RX-7, the twin-turbo rotary built for that chassis starting in late 1991, with a little over 55,000 km on it.

What this engine is

The 13B-REW is a two-rotor Wankel engine with sequential twin-turbocharging, where each rotor carries a 654cc combustion chamber for a combined 1308cc of displacement, or 1.3 liters. Factory output is rated around 255 horsepower and roughly 217 lb-ft of torque, with a 9.0:1 compression ratio and multi-port fuel injection, spinning up to a top end somewhere between 8,000 and 8,500 rpm, using one primary and one secondary turbo working in sequence rather than a parallel pair.

What comes with the unit

Rather than a bare long block, this pull keeps the wiring harness, intake and exhaust manifolds, and factory ECU and injectors attached to the head and block, and throws in the 5-speed manual transmission, starter, clutch, alternator, and A/C compressor on top. Whatever shows up in the listing's own photos is what ships with the unit, so treat those images as the final word on exact contents.
