dodge mazda
one complication i see with the six rotor is the length of the bolts needed to keep them together other than that firing order works on 360 degrees divided by six running in alternating pattern just like the four rotor 1,3,2,4 firing every 90 degrees so some simple math and we would be good, the other problem i am having right now is finding a sufficient amount of these engines to slam together and be carb, not fuel injection.

hey
OK. don't they use six rotor in aircraft though? can the 20b 3 rotor be compounded together if so wouldn't that solve the stress issue if the shaft is already able to take a three rotor attaching one more set shouldn't cause that much of a difference?
ok on top of that what turbo would you use one large or two medium size turbos.

That was just a mockup done by Hurley Rotary; it never ran. The timing of this thread is funny because I was thinking about the engineering issues of a five- or six-rotor just this morning. The problem is just as Brodie121 says: e-shaft flex. The longer the engine, the bigger problem it becomes. That's why everyone stops at four (that, and turbo four-rotors are capable of such obscene power that it's unnecessary to go any larger in practice).
I don't mean any offense, but from the sound of your posts, you are not a professional mechanical engineer, so I recommend giving up on the idea of a six-rotor. Pay Jeff Bruce to build you a four-rotor kit, slap a turbo on it, and have fun.

ecu issue
how do you get around the ECU issue with a 4 rotor without having to spend 3000 on a Stand alone engine management unit because i want to turbo but don't know if there is a solution for carburetors, which would mean i have to do fuel injection but what do i do run both separate ecu

Carbs suck. They are just a slightly controlled leak.
As I said, I hope you have alot of $$ a real standalone is going to cost you $3000+
There is no way you will be able to complete such a project for cheap. Just being realistic.

pretty good forum
there was a pretty good forum "ghetto 4 rotor" going for a while and it was insight full, i am thinking of 4 rotor 13b dual with a huge turbo out of my buddy's 1996 dodge ram he is giving me i am thing about more than 500 horse after i am done thats what i am aiming for.
