Hayward Rotary are able to offer engine tuning for both
carburetted and Fuel Injected Rotary Engines.

Please Contact us for pricing and to discuss your tuning needs.

Hayward rotary has a vast experience in carburettor rotary engines, our 4 rotor and our current 3 rotor racing cars both run normally aspirated engines utilise the Webber IDA. The Webber 48IDA is our aftermarket carburettor of choice for racing and high power applications. This is often modified to a 51 IDA, and we can carry out any modifications you require to IDA’s.

We have also completed several conversions from Gen 2 EGI to Dellorto Side draught carburettors, increasing power output. Racing applications aside, we have a great knowledge of the carburettor provided by Mazda as standard on their 10a and 12a blocks.
So whatever your Carby need give us a call.

We are able to offer ECU tuning to the very highest standard for :
· APEXi Power FC
· Microtech


We have over many years developed our own unique maps for the above ECU's.
We map all of our cars for drivability and longevity whilst still maximizing output.
