Mazda RX-4 13B Rotary Engine Workshop Repair Manual

Mazda RX-4 13B Rotary Engine Workshop Repair Manual PDF. The 13B is the most widely produced engine. It was the basis for all future Mazda Wankel engines, and was produced for over 30 years. The 13B has no relation to the 13A. Instead, it is a lengthened version of the 12A, having 80 mm (3.1 in) thick rotors. It was a two-rotor design, with each chamber displacing 654 cc so two chambers (one per rotor) would displace 1308 cc; the series name reflects this value (“13” suggesting 1.3 litres), as with the 13A of the same displacement but different proportions.

In the United States, the 13B was available from 1974 through 1978 and was then retired from sedans but continued in 1984 – 1985 RX-7 GSL-SE. It disappeared from the US market again in 1995, when the last US-spec RX-7s were sold. The engine was continually used in Japan from 1972’s Mazda Luce/RX-4 through 2002’s RX-7.
