Default 4-Rotor Kit Group Buy! Defined Autoworks

Finally after much development we are proud to announce our 4 rotor kit group buy!

Never before has a company based in the U.S. offered such a service. I have already kick started the process and have enough of the complex parts on the shelf to build 4 sets of 4-rotor engines.


Why go with Defined Autoworks?

My personal 4-rotor has been running flawlessly while being beaten on the racetrack at over 10,000rpm without skipping a beat. Making over 610rwhp (720+hp) its currently one of the highest documented 4-rotors naturally aspirated.

Why go to a place that has never even built a 4-rotor? Why go to a place that has never even raced and tested a 4 rotor sucessfully? Those are the good questions to ask.


The infamous build video-

Being in the U.S. gains another massive advantage, no more shipping of your valuable parts overseas. Shipping round trip of four cast iron housings is over $2500.

This cost is saved and the risk of damage or customs withholding your parts eliminated.


4-rotors are complex machines, and the undertaking not for the faint of heart. I'm sure there will be many questions and I welcome all to help explain what is being offered or what else is needed. Anyone involved in this group buy will get technical support from me personally. While this is not a unlimited amount of time, I will assist in the general assembly or advice from my years building multi rotor motors.

Additional items to compliment the 4-rotor kits-

We are a one stop shop. I build and fabricate custom drysump kits that will out-flow the mazda comp units. The regulator is externally adjustable and the length of the engine is reduced.

Also offered is fully cnc made slide throttle setup. Provides the best power and flow of any intake. Fully roller bearing supported and reliable.

Lastly if anyone wants other 4-rotor parts, such as full p-port housings or lightened rotors, anything can be provided from A-Z. Full builds and complete engines are no issue.


Only part not in stock is the 4-rotor eccentric shaft due to the cost. Wait for this item is 2-6 months.

4-rotor kit pricing-

2 person group buy $9200
3 person group buy $8700
4 person group buy $8200
5 person group buy $7700
6+ person group buy $7500

Things needed to be sent in-

Two front stationary gears, One 86+ front counterweight, Two intermediate irons to be modified, will need front and rear cast iron plate for center line machining.


Slide throttle assembly pricing-

2 person group buy $3900
3 person group buy $3400
4+ person group buy $3000


Defined Auto Competition drysump setup

2 person group buy $5000
3 person group buy $4800
4+ person group buy $4200













4-rotor slide throttle





Drysump system
