ghetto 4 rotor build

4rotor
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.

That autocrossing REPU is pretty sharp. I'd like to do something similar in mine.
There was some concern on the rotor weights but I assured him that we'll dynamically balance them before assembly. Therefore the counterweights can be made with a general weight, such as that posted on Mazdatrix' website in the rotor weight and compression chart.
Hey Viking, that dual 12A is pretty cool. My friend has a plate and a coupler thing for two 4 port 13Bs. The whole contraption will be longer than the dual 12A, and not just due to the longer rotors. It's essentially a less elegant solution than the ausrotory one. Of course the 'ghetto' 4 rotor build we're doing in this thread will result in the shortest engine possible with 12A parts and some intermediate plates.
So there.

This is a fantastic thread
Out of interest how does the oil get into the rotors ?? Is is passed down through the shaft or done further out ? If it goes down the shaft has the splined portion been bored out, looks just like a center. Very beautiful piece of engineering. Wish I was as adventurous.
Can't wait to see the engine running

i loving this build but getting parts here in jamaica is hard next to impossible
cant even get a 12A out here planning on ordering from the US or NZ or AUS but not having any luck finding people with the engines for sale.
sorry to go off topic good build keep it up so that i can learn and maybe try it later wen i get some of these engines and post some more links to help jeff and others out
jeff u try a turbo 4rotor build next time

Jeff, this is an amazing project! I'm eager to follow your progress.. moving fast already! Keep it up!
Will you be running fuel from Megasquirt or alternative, or carb?
Cheers,
Paul.
