Defined Autoworks 4-rotor kit group buy!
10 Attachment(s)
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 Attachment 634879 Attachment 634880 Attachment 634881 Attachment 634882 Attachment 634883 4-rotor slide throttle Attachment 634884 Attachment 634885 Drysump system Attachment 634886 Attachment 634887 Attachment 634888 |

So much win for this GB. Had I any money left, I'd jump all over this. Logan is THE MAN for 4 rotor builds!

This is awesome, I wonder how much it would be for a turn key option, I'm just dreaming for now.

2x complete center irons with inserted stationary gears and direct oil feed provisions. (irons and stat gears customer supplied) 1x set of 4-rotor bolts 1x rear counterweight 1x modified front conterweight (customer supplied) 1x full length dowel pin 2x half length dowel pins |
After being brought to my attention, I will now be offering a 12 month finance option on the group buy. :)

Damn... Killing me with that.
How does the motor mounts typically work out? Not really thinking of this for my FD but maybe for my rx8 ;) |

Pricing isn't bad considering what it comes with. Nice work.
|
Dear god...Time to sell everything I own. This is going to spawn a whole new chapter of build threads and mod tech. Someone buy one and get to it!!

Thanks David! I say dig through the couch cushions :) Then you can start a new 4-rotor thread and be famous all over again!
(This is not meant to be negative, or sarcastic or condescending. But rather point out that i have heard nothing but positive about defined!) |
^ 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!

Im in for the group buy if it the price can be down in the 6 or 7+ price range.

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!
1) Member #1 2) Member #2 3) Rxmfn7 (dependent on 6 joining) 4) 5) 6) |

Here is a pic of the Defined 4-rotor using the same parts from the group buy. Helps clear up exactly what it looks like together (although a bit of a fancy trim)
I will post full measurements as well to help anyone trying to see how one of these badboys would fit their chassis. Attachment 634473 Attachment 634474 |

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? |
Why are there 3 crank angle sensors? Are you changing more than one ecu together so it'll work on a 4 rotor?

Front center and rear irons (two additional irons are sent in to Defined) Front and rear stat gears 4 rotors 4 rotor housings 2 x 13b gaskets sets 2 x 13b apex seal kits 2 x 13b complete spring sets 2x 13b oil control rings and seals Front cover. Balancing is mandatory Stock oil pump can be used but only to limited rpm. Drysump is needed if over 7000 rpm |

Cool. So it's running with a single TEC3R? I didn't think it could do it.
