a rather general question- is this a proto or a working unit? How long has it been on the road?

 

Hmmm...good point. Yet another aspect I never thought of.

But then again, what 20B has long service life as it is? Ppl use 'em to make gobs of power in cars that are rarely driven. 30K miles on the motor would be like what...10 years lifespan at my current driving rate?!

Just when I thought I was starting to understand...

 

They do not use a dry sump setup. They use a custom oil pan. It does not have to be as low as stock to have a large capacity since the pan is longer.

The shifter stays in ALMOST the stock location. It does sit about 2-3 inches behind the original position. This is accomplished by moving the shifter housing forward along the transmission. To do this, the shifter housing is mounted by only its rear mounting location to the forward mounting location along the transmission housing. The two original forward mounting spots along the shifter housing are cut off.

That is their second version of the 23A. The first version had severe e-shaft flex so they redesigned the e-shaft. The car with the new e-shaft was at the last Sevenstock but was barely finished being put together.

One of the advantages of their 12A based 4-rotor is that it is only slightly longer than a standard 20b 3-rotor since the housings are narrower.

26B n/a down here in NZ

 

Isn't the 4 rotar scoot FD in japan made form 2 12As? But they said it wasa 3.0L engine...how do you displace a rotary exactly, do you carve larger pits in the rotar itself? Becasue I know the 13b gain another 100cc by widenning the entire block.

 

Oh my God. That car is insane.

 

BTW....HOLYSHIT...wow....I love you NZs!!!! My girl friend is a kiwi and she wants to take me there and show me around I said I'd go but I would want to barrow an FD while i am down there hahaa! Can I barrow the 4 rotar?

 

FOURRE is definately pretty mad - although I've heard rumours it's lunched itself.

If you're down in NZ Xeros, I'm sure the FDKai club would accomodate you :P

 

Wow! amazing.

 

any one know the time on that 4 rotor NZ FD? that car is simply amzing, and since he never sat there and burned out just got up and wnet he probly got some sweet times. man i'de love to have one of those 26b's even a 20B proplery done up, no Turbo jsut pure power, would be amaing like GtoRx7 20B NA i would serisouly consider making a similar rip off project once i get to know Rotaries more and have over $10k lying around to play with. but thats all hopes and Dreams/ Goals for right now, can't wait till money starts flowing into my possesion.


Prôdigy

 

It runs mid 10's... 590hp

Another video of it here : http://onionz.com/albums/afterburner...otor_video.mpg

 

I wonder if they have a dyno sheet of that 4 rotor...

 

I emailed them a few days ago without response. So does anyone have an idea on the cost of the shafts? Also what other specialty parts are needed to build with one of these shafts, IE housing mods, center bearings, etc?

 

Found a semi decent pic of FOURRE's engine bay...

whats the most amount of rotors someones done, or actualy CAN be done assuming you have unlimited funds? anymore than 4? not nescessarily in a car, but in general. would be interesting to see something like a 12 rotor!

 

damn...wish i had that kind of cash.... I would probably go with a tri rotor. I think the tri sounds better and i think i would be happy with 650rwp with the tri.

 

Thats too much for me.

 

Think aero and you will find the answer

 

I've only ever seen that car in pieces in their garage, so its a proto. When I use to go their garage to get repairs frequently I was always asking when it would be finished, but it seemed like they didn't have the funds to put the project on the fast track. One of the mechanics had a first gen RX7 with a 13BREW in it in working status, and I think has raced it at the local stadium races.

I wonder whats the story now but I don't feel like driving 50 miles to check.

 

that pic of the fourr car doesn't make sence. it has lhd wiper arms but it has the wiper motor on the side for rhd wipers. ????? alittle off topic

 

this car seems exciting in pictures and writing, but anyone who has seen it will agree with me that it is some of the sloppiest fabrication ever. I shuddered when I saw the intake manifold, and pretty much everything else. I understand that when they first ran it, they found the oil pan full of metal shavings! I also don't think that it even runs anymore... they wouldn't start it up at sevenstock.

I hate to talk ****, but sorry guys this is not your holy grail. I wish it was; I'd love to see someone come out with a real 12A based 4-rotor setup for sale that wasn't complete ****.

 

yeah there are ppl that build more than a 4 rotor hurley built a 6 rotor 900hp NA

i have seen a 6 rotor that is called a 12 cylinder killer i will try to find pics of it

 

I have a few issues of RX-7 Magazine from over in Japan that have a 12 page spread on the 12A based 4 rotor from Scoot. If yall really want it, I can take scans and post em up. It's all in Japanese though. It litterally goes into complete detail though, breakdown of the rotor housing, multi-piece e-shaft, porting, etc.

 

RedR1, that would be sweet if you could post those scans up.
