How big is a Mazda 13B rotary engine?
The thickness of rotors was increased to 80 mm (3.1 in). The 13B looks like a lengthened version of the 12A in this case. The total displacement of two chambers is 1308 cc (1.3 liters). The first 13B engines had carburetor fuel system and single distributor in the ignition system. Cars using this engine used the AP name (1974-1980).
What kind of fuel injection does a Mazda 13B use?
The 13B-RESI engine (Rotary Engine Super Injection) got Bosch L-Jetronic fuel injection system in 1984. This engine also received a unique intake manifold with two-level intake box which provided a supercharger-like effect from the Helmholtz resonance. The new technology significantly improved power and torque of naturally aspirated 13B engines.
What kind of engine does a Mazda 13B-MSP have?
The name Renesis is a combination of Rotary Engine (RE) and Genesis. The abbreviation MSP is Multi Side Ports which make the engine different from its Mazda’s rotary predecessors. Instead of the 13B-REW, the 13B-MSP is a naturally aspirated (NA) engine.
What kind of Turbo does Mazda 13B Rew have?
The REW indicates that it is a rotary engine supercharged by twin sequential turbochargers. This is the first engine in the mass-production with such turbocharger system. The 13B-REW got two big Hitachi HT-12 turbos.

How much torque does a 13B-T engine have?
The 13B-T engine features the four port intake design which similar to early 13B engines from 70’s. The use of a turbocharger gave the noticeable improvement in torque. The output of late 13B-T was 185 hp (138 kW) at 6500 rpm and 183 lb-ft (248 Nm) at 3500 rpm.
