Lets get some thoughts here..
I was remenising about last summer when I wanted to build my own 3 Rotar 12 A engine..
I scowerd local junk yards for donars, old rx7s that bit the dust long ago..
But, balked when I actuly started to think about what I was doing..
Lets say, I find 3 perfectly intact 12 A's.. I would be more than half way to achiveing my goal..
But, even if I did find the housings and the rotars.. I wouldn't have the ecentric shaft for it..
I thought to my self..well..I could find an old 20b and use it's shaft.. that has been done before.. But, then I would have to buy a whole 20B and that would defet the purpose..
I thought to myslef why hasn't a tuner attempted just to build custom E-Shafts for people..
I think there would be a great market for that.
What about you guys?

Look up a guy in New Zealand names Jeff Bruce. He makes them. He makes 3 and 4 rotor versions and even a custom e-shaft with provisons for a center bearing. He made the Hitman's motor. Jeff's e-mail is: precisin@ihug.co.nz

I was thinking Titanium or Carbon fiber...
Issue there would be the internals would get eaten up..they would have to be made of equel or stronger stuff..

I've learned so much in this place...
How do they make 3-rotor engines? I've seen the rotor housing and it looks like they simply attach (per the Renesis) these things together. It looks relatively straight forward while needing some custom parts, ecu, etc.
So, I wonder what a 3-rotor Renesis engine could do? Does adding another rotor add a certain amount of HP. What I mean is...
1 rotor (if there was such a thing) = 125HP
2 rotor = 250HP
3 rotor = 375HP
Also, how does this apply to fuel economy? 1 = 23/30 2 = 18/24 3 = 14/20
Note: It's probably similar to what happens moving up from I4-V6-V8-V10 etc
Not to sidetrack the thread...I would just like to know more about these 3-rotor engines. Heck...if the fuel consumption is not hit to bad when the Renesis dies (150K+ miles I hope)it might be better to simply stick a 3-rotor in there instead of swaping out engines.

Cool...thanks, maybe Mazda should be talking with Mr. Hurley regarding the next RX8 update.
3-rotor 340HP...yum yum....
Heck, he even got slightly better fuel economy out of his 3-rotor. I wonder when and If he is going to do something with the Renesis?

Hmmm...so custom is the only way to go.
