There is another site that has the same kit for the same price... I believe the other site has a picture though.
I may be off by 247$ but for it to be shipped and insured for 8,300$ yea more then likely going to be around 8500$ shipped

"4 Rotor Crank Kits $9,500.00AUD = 8,253.33 USD
The 4 rotor kit has the following:-
1:- Eccentric Shaft
2:- Front counter weight
3:- Rear counter weight
4:- 2 x Centre plates
5:- 2 x Stationary gears (modified)
6:- 2 x Stationary gear carriers
7:- 2 x Stationary gear external oiling mods
8:- Rear main nut
9:- 2 x eccentric shaft end caps"
Building a 4 rotor won't cost 60K
Even Kiwi's 4 rotor KIT isn't $8,500

Go ahead, build one and get back to us. Funny thing is that for all you big dreamers there isn't one of you who has built a 3 rotor by the looks of things let alone a 4 rotor. A proper 3 rotor build will cost you over $8500 for christ sakes and there are a pile more of them around than 4 rotor engines. Don't believe me then, see if I care. All I'm trying to do is keep it real instead of blowing sunshine up someone butt.

lol, solracer, adding extra rotors and housings is MUCH more feasible than trying to turn a v6 into a v8. for the latter, you'd need a whole different engine block. As for making a 2-rotor into a 3- or 4- rotor, you just need additional housings, rotors, and a new E-shaft

I try to stay away from cursing on this site but....
DAMN WHAT A GRUMPY ****!
You shooting for **** rocket of the year there solo racer?
You know according to your logic we shouldn't try to do anything unless we already know all about it... So I guess we should all still be cavemen then?!?
****, two years ago I was introduced to the rotary concept and now I'm building my own 20b. If I had listened to **** heads like you when I was getting into wankels I'd never have learned anything...
Oh and a stupid question is one that is erroneous or shows complete and utter ignorance of ones ability to think. Asking about joining rotors and trying to understand the basics of a four rotor engine is an excellent question for someone who has no advanced knowledge of a rotary engine as it gives him the opportunity to understand that more than just joining rotors is required. However asking if it "sounds fair to you guys" that you act like a bullying 2nd grade *** **** to some guy trying to learn something new IS a stupid question especially when you specify that he should learn the basics before asking about four rotors!!! Now how pray tell, Lord of the douche, are you supposed to learn the basics about something without asking questions?!?! Is he supposed to just sit there and meditate on the idea of a four rotor?!?! Maybe you didn't pull those numbers out of your *** but your brain certainly made its way out the back door after you couldn't get your mind off the dick you had up there!
People like this guy almost stopped me from buying a RX-7 two years ago...
Oilcan I encourage you to build a four rotor just to spite this **** dyke... If you need any information pm me as I have been preparing for a four rotor race build after I finish my three rotor daily driver and have alloted a good deal of technical information.

When you first came on here did you post "I'm going to build a 3 rotor....how do you join the rotors?" or did you actually take the time to read the information on this site and learn how the rotary works first? Remember the first post this guy makes is "how do you join rotors to make a 4 rotor" when his first post should have been "How does a rotary engine work?" Pretty much tells you the guy isn't serious or a kid with a dream. It's a good chance that he is probably not mechanically inclined no matter what his blustering says. I can't think of one mechanic that I know who would post something as naive as that for his first post.
No he shouldn't meditate but there is plenty of information on this website and others on the basics of how a rotary works and if this guy isn't willing to at least spend the time to read about them then what do you think is the likely hood of him ever building a 4 rotor do you think? And if a guy isn't willing to put in at least the minimal amount of time to search the web or this forum why bother with him? He's obviously just yanking our chains and isn't serious.

I've done assloads of research over 3 & 4 rotor engines. I was contemplating a 4-rotor or a short crank 3 rotor at one point but I decided to build a 20b 3-rotor instead. No one ever argued that a 3 rotor would cost less than $8500..... I know what this stuff costs.
I'm not blowing sunshine up anyones ***, there is alot of $ involved in these engines. A lot of research must be done before someone decides to dive right in one of these types of projects.

Pineapple Racing has a 4-rotor sitting on the shelf...granted it's probably not up for much more than a research for ideas. Call up Rob and ask a bit about it, you can learn a lot form him.

as i read through this posting i see alot of negativity about dreamers. without dreamers you would'nt have the 4-rotor in the first place. the 787b would have never existed, heck the wankel would never have existed.
it seems that if wankel was alive and used the forums of today, to ask opinions on his idea, he would be shot down and the rotary engine would never have come into existence.
it took me a good 5 months of searching to find out what i needed to know for my build and i still dont know everything. instead of trying to be "realistic" just give some websites for info and wish the man good luck. there are plenty of feesable 4-rotors racing/driving. you just have to be willing to put in the work/money/time.

what do you consider plenty? i mean since its a "impossible project", should'nt one suffice?
lets say we go off the number one.
there is one 4-rotor fd in australia.
one 4-rotor turbo bmw
and we'll just use one japanese example which is made by scoot.
yes there are more but since its impossible, one should be enough.

"Imagination costs nothing; we could build square locomotives or fly to Mars" - Felix Wankel
The Wankel is a product of a dreamer if you hate dreamers than why the hell do you have a rotary...
Also yeah when I first got into rotarys I did ask the same questions as this guy...
And you ever try a search yourself, you can't find anything because every fuckign thread you come to is gooked up with negative bastards like you.. you can never find any info only nay-sayers...
Why are you even still posting on this thread? You are contributing nothing and just tearing everyone down for trying to accomplish anything.

"I Believe I Can Fly"
I used to think that I could not go on
And life was nothing but an awful song
But now I know the meaning of true love
I'm leaning on the everlasting arms
If I can see it, then I can do it
If I just believe it, there's nothing to it
[1]
I believe I can fly
I believe I can touch the sky
I think about it every night and day
Spread my wings and fly away
I believe I can soar
I see me running through that open door
I believe I can fly
I believe I can fly
I believe I can fly
See I was on the verge of breaking down
Sometimes silence can seem so loud
There are miracles in life I must achieve
But first I know it starts inside of me, oh
If I can see it, then I can do it
If I just believe it, there's nothing to it
[Repeat 1]
Hey, cuz I believe in me, oh
If I can see it, then I can be it
If I just believe it, there's nothing to it
[Repeat 1]
Hey, if I just spread my wings
I can fly
I can fly
I can fly, hey
If I just spread my wings
I can fly
Fly-eye-eye
Sorry I had to do this.

There are working 4 rotor engines and it is not impossible. Mazda made several for use in racing competition including one that allowed them to win the LeMans in '91 (using the IMHO amazing 787B), a first for both a Japanese company and for a non-piston engine (because we all know how many non-piston engines there are outside of Mazda).
Here is a page with quite a bit of literature:
http://cp_www.tripod.com/rotary/pg03.htm
Other private companies and individuals have done it themselves, using both the 12A and the 13B in pairs.
In short, it is entirely possible; the main difficulty is the price due to the customized nature of the project. Many of the parts that you'd need, such as the eccentric shaft, are not made, at least for sale, by Mazda. So you'd have to trust a third-party dealer or a mechanic/engineer skilled in fabrication.
I don't have any ballpark estimates, but its safe to say that this is a pretty pricey endeavor for anyone to undertake, unless you are very skilled and the company you work for is ok with you using their tools and materials.

True. What makes this even worse is that once your search comes up with nothing, you have to wait like 20 seconds before you can do a new search that turns up empty....

it can be done i live in new york if you go to amv racing.com talk to oscar. i'm in the process of building one right now sure it gets expensive, but if you want it and have patience you can do it. oscar is the distribuitor for kiwi-re. on the website you can see how my motor is goin to look. he has carlos lopez as the engine builder.

it's going to be a twin turbo,street driven going in to a fd. i bought the kit from amv but from there they have to do a lot of modifications to it. a lot of custom work, it gets expensive but it all depends what do you want. oscar has a first gen with a 4rotor non turbo. engine management you could use a microtech. but you cant just buy the kit and plan to put it together it takes a lot more. the kit comes the shaft, two modified plates,counterweights.then you have to buy the bolts and you have to specify what series rx7 you want it based on and if is going to be turbo or na. go to amvracing.com go to rotary engine building and you would see how its going to be.

--------------------------------------------------------------------------------
if anybody is interested i'm in the process of building a 4rotor twin turbo fd for the street and is based on 3rd gen parts i have bought everything brand new.
4 rotor housings, 3 plates,the eccentric shaft kit that comes with the 2 plates,10mm stud kit,3mm competition apex seals,all the gaskets,all the springs and seals,race rotor bearings,stationary gears,stationary gears bearings from mazda speed,dry sump,injectors,ecu for the 4rotor,coils,twin disc carbon carbon clutch,two turbos,wastegate,turbo manifold is being done,. and other stuff that i'm forgeting,bottom line is the the engine needs to be finish putting together,i ran out of patience if interested i'm selling everything i would put anybody who's interested in contact with the person who's building it. i have all invoices off everything i bought for this engine brand new. i have a lot of money invested in this project, if anybody is interested pm me and i will give you my number so we could talk. i want to buy me a supra or skyline something that i can teardown and put back together cause i dont know how to work on rotaries.
also for sale is the 93 rx7 that this motor is goin in to if i dont sell the parts, is red tan leather interior,96,000 on the body,great chape,real clean,it has kazz lsd,chromoly,axles,433gears,hks coilovers,dual in tank fuel pumps,dash10 fuel lines all the way from the pumps to the front,rear seats,short throw shifter.body is stock.
