What is the difference between a 12A and a 13B?

What is the difference between a 12A and a 13B?

While the 12A was a complete redesign using what mazda learnt from the 10A, the 13B was a povo attempt at a bigger block rotary still using 12A parts, ie plates. If Mazda were serious they would’ve created new geometry for the bigger block model insteading of just adding another 10mm onto each rotor.

What do turbo manifolds do?

A turbo manifold is a series of runners, or pipes, that collect exiting exhaust gases which can then be channelled into a merge collector. A flange is needed to bolt the turbo to the manifold, and this is welded/cast to the merge collector.

Can you put a turbo on a rotary?

Nothing can be compared to the feel of a rotary engine that is turbocharged. A turbocharged Mazda RX-8 provides for higher output levels and a smooth power delivery. It is ideal to place the turbo low in the chassis in order to yield low temperatures under the hood.

Can you put a turbo in a rotary engine?

Basically yes. It uses exhaust gas to compress incoming air to provide more of an air charge to the engine than ambient pressure could provide. Turbos are turbos.

Do you need new headers for a turbo?

no need for a header. and make sure the exhaust is at least 2.5″ in diameter.

Can you use headers with a turbo?

You technically can. It would have to be a custom turbo system that mounts the turbos somewhere in the exhaust after the header collector. Something like the STS turbo system. But most (if not all) aftermarket companies utilize the stock exhaust manifolds, because they work properly with most people’s power goals.

When did the Mazda 12A rotary engine come out?

Mazda 12A Rotary Engine Review The Mazda 12A engine is a Wankel rotary engine produced from 1970 through 1985. The 12A is reduced in displacement the 10A engine (the first rotary engine in mass production). The engine had a two-rotor design also, the same rotor radius.

What kind of steel are Mazda 12A rotors made of?

The Sheet-metal Insert Process (SIP) was used since 1974 for reinforcement of the rotor housing. The SIP is a sheet of steel with a chrome plated surface. The rotors were made of cast iron. Chrome-molybdenum steel was used for eccentric shafts. The rotors were equipped with aluminum/carbon apex seals.

Which is more reliable a turbo or a rotary engine?

It should be noted that the naturally aspirated 12A engines are far more reliable than turbo versions. The N/A 12A engine with correct maintenance doesn’t need a rebuild before 150,000 miles. Be prepared for the fact that the engine consumes a lot of fuel. Because of all rotary engines have a poor fuel efficiency.
