Hayward Rotary are able to offer all types of services with regards to Mazda Rotary Engines. We have experience in building and maintaining all stock Mazda Rotary Blocks, Rotary Race engines which are track proven, or bespoke engines,
such as our 4-Rotor.

We will give you a fixed quote for your Engine work, not an estimate. All of Engines come with full warranty including against detonation. Please contact us for information and a quote
Below are a few Examples of our Engine work.


 

13b twin turbo
Here is an example of the type of 13b twin turbo engine that we provide regularly. This engine was fully rebuilt to the highest of standards using uprated internal part’s. We also carry out basic power and reliability upgrades: Uprated Air Filter - This will allow air to enter the turbochargers at a faster rate, due to its less restrictive nature. Uprated Free Flow Exhaust - As with the filter this allows air to flow freely through the engine, creating quicker turbo spool, and more power. Uprated Front Mounted Intercooler - This reduces intake charge temp, allowing more fuel to be added. Uprated Injectors - This is to allow for proper use of the intercooler, filters and exhaust allowing us to tune the car safely.







13b single turbo
Here is an example of the type of 13b single turbo engine that we provide regularly. This engine has been fully rebuilt to the highest standard’s using uprated internal parts, this engine differs from the stock unit in that we have fitted it with a GT35/40 turbocharger. We strongly recommend the use of the GT35/40 for street and race applications due to its quick spool and its capability to make good smooth power throughout the rev range. To allow the high power levels to be made efficiently and safely the car has been fitted with the following upgrades: Uprated Air Filter - This will allow air to enter the turbochargers at a faster rate, due to its less restrictive nature. Uprated Free Flow Exhaust - As with the filter this allows air to flow freely through the engine, creating quicker turbo spool, and more power. Hayward Rotary V-Mount Intercooler - This intercooler and radiator has been specially developed and designed by us and vastly reduces intake charge temp at all driving speeds, thus allowing more fuel to be added. It also shortens the inlet tract length considerably over a front mount intercooler setup. Uprated fuelling - This is to allow for the additional amount of air volume that the turbo, intercooler and exhaust will allow. Hayward Extend Port - This allows the air to enter and exit the engine more efficiently, by allowing us to change the timing/duration of the inlet charge of the car and change the power characteristics of the engine.

Race prepped block
Here is an example of a ready race prepped block that we have made for our drag car, with large extended side ports, this block is to be coupled with a large frame turbo upon assembly and will be used for drag applications. We believe that this block and the internal/external modifications that have been undertaken on it, coupled with the correct turbo set up will be very capable of producing more than 700hp initially and upwards of 1000hp later on.
