i have heard some where that you can basicaly slap to rotory engines to gether with the edition of a new crankshaft and make a 4 rotor is this true (over simplified of corse)

 

No It is not. The only way this would be true is if you used two mid inetermiadiate plates from a 20B motor, then you could get past 3 rotors. Goold luck fabing everything else.

On a serious note, thses 4 rotor swaps usually cost somewhere around 100K to do, not worth it in my opinion.

 

100k is REALLY pushing it.

I'd say they usually go about 10-15 methinks.

20b turbo sounds like a better plan to me.

I read a web article back in the day about a guy that stuck 2 13b's together in his sprint car. Just made a connector. If I recall correctly, it didn't work very well.

 

plus, how would you control the timming unless you used a haltech with direct fire. i do think it can be done, but lots of work must be put into it. if there were companies that started manufacturing intermediat housings and another which did manifolds then the 20b would be very easy to make. I know in aussy there is a company that sells 3 and 4 rotor eshafts, lightened eshafts! but you would still need the other parts to do a proper setup.

 

there's indeed a guy with a four-rotor thats simply two 13B's bolted together with a special adapter.
A real four rotor is a lot different though. You can built one by using two engines, plus a special intermediate plate (taking stationary gears) and E-shaft.
Of course you'll need special goodies to control that engine.
