Defined Autoworks 4-rotor kit group buy!
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.

Since the 4 rotor has no "default" configuration, the sky is the limit if planned ahead on mounting. A first gen front cover can be used for motor plate style, fc center irons can be used and gain three possible positions to mount on the side/bottom of the engine, or Fd rear iron in place and utilize rear bottom mount. Lastly if using Re rear and last center side Mount identical to 20b can be used. I can machine Fd irons to use 20b bolt patterns as well

^ Only screwed twice Dan? I'd say it was a lot more than that
Would like to be known for an awesome Defined 4 rotor build and I would jump all over this if money were available. The wife unit would shoot me if I did this right now and she'd be right to do it!
I would not hesitate to take my car to Defined. Logan's work and craftsmanship is at the top of the industry.

I have to trust that this would not make him famous (IMO). Knowing David (not as well as i'd like), it seems that a lot of his "fame" was a result of being screwed not once but twice. I will say his dedication has maintained his fame. but i hope no one ever has to gain fame the way he did!

Looks like two are signed up, if Lenny joins that would leave 3 more needed to get in the $7500 price point. Quite a few are asking for identity to be anonymous so nobody will see the build thread coming, understandable since these typically take a bit of time to complete!

Okay so I'm really contemplating this. So this would be for parts to build a block? Or would the price be for an assembled block?
I know all the other stuff such as slide throttle, intake, ecu, etc is extra. I'm just seeing what the kit entails..
Looks like we supply the rotors and housings correct?
