Mazda is — and has been for a lot of a long time now — one of many final producers to imagine within the functionality of the rotary engine. The 13B-REW is proof that Mazda’s efforts to develop the distinctive design have been warranted, because it supplied a suitably potent coronary heart for one of many model’s most celebrated vehicles, the FD RX-7. It featured a specifically developed sequential twin-turbo system, the primary of its variety, to remove the turbo lag that had plagued earlier turbocharged engines. It wasn’t the primary 13B to be produced, as one had already been in use for years in earlier generations of the RX-7, however the twin-turbo version was particularly special.

With simply 1.3L of displacement, Mazda wrung sufficient energy out of the engine to hit the 276 horsepower restrict of the gentleman’s settlement. There was additional room for enchancment too, as within the following a long time, tuners have constructed engines with greater than double the quoted inventory output, albeit usually at the price of reliability.

Despite not producing a brand new automobile with a rotary engine for greater than a decade, Mazda continues to make new 13B engines at present, with a small staff of craftsmen on the model’s manufacturing facility dealing with every thing from machining elements to last meeting. Each new engine is accomplished by a single engineer, and simply two examples are produced day by day. They’re out there to order from Mazda instantly, each to switch damaged engines in growing older vehicles and, in idea, to create new rotary builds, too.
