There is a new 2 cyl engine from Fiat, 900cc, very compact, for his new fiat 500, it seems too tall but maybe its short enough to fit.

Nice a new Fiat engine for the 2cv....,
However you at least need a new sump, cause this one is too high/deep in relation to the level of the crank/flywheel.

Found some pict of a 2cyl panhard engine atached to a 2cv gearbox:

Look at the gearbox shift command in the 2nd pic.

Is it ever been done to put some 2cv engines behind each other and connect them ,I am thinking about doing this for a new project for the next worldmeeting and i would like to use three engines in a row to build a six cilinder boxer engine with 1806cc capacity .If there are some ideas about that it would be nice to share them with me because i think to have a way to combine these efficiently but maybe some new input can improve the build quality.And how many BHP would the original 2cv gearbox hold because it cold make 90 BHP or should i upgrade to a visa or ami super gearbox.

I think that the crankshaft at the turbine side cand hold much power. I think that a parallel arrangement is better than a serial.
My idea for this is replacing the flywheels by toothet pulleys, mount the engines in a common rigid frame and run a parallel axis to transmit power by toothet belts (allowing to sincronize engines).
And for gearbox you better use a completely diferent thing than 2cv or GS ones.
You probably can take some inspiration from dragster with multiple engines

Examples for the toothed transmision for a 2cv engine:

http://www.recreationalflying.net/forum/avionics-engines-props/51415-citroen-visa-engine.html

http://www.ultralightflyer.com/citroen_aircraft_engine/index.html

http://www.ultralightnews.com/airv98/airventure_citreon.htm

But examples of taking power from front side also exist:

http://www.eel.de/deutsch/ulf-2_bilder.htm
Another:
http://forums.bmaa.org/attach.aspx/4443/untitled.bmp

As you can see, in the last examples you need to provide a external bushing to prevent bending the front part from crankshaft

@ JUAN NAVARRO

thanks for your input .It is worth thinking about those techniques

i think that those rebuild engine used for airplanes have paralel shaft to improve to run higher rpm on the propeler and because the propellor has wide diameter they make bigger shaft on it ,but i was thinking when i put engines behind each other it would be possible to mount a tooted coupling on the fan shaft to connect to another engine without flywheel but with mirrored coupling mounted on the crankshaft .When i use 3 engines i would rotate their timing against each other with 240 degrees for each engine his working cyclus .This to letting them follow up each other in firing that it would be possible to let the package run smooth.

Maybe this is Offtopic but..

Your idea reminds me of this radical project:

I was thinking to use a claw coupling but this could also do the job but i would like to buy the without center hole so i can machine the flywheel patern from the crankshaft and the cone on the front of the crankshaft into the clawcoupling .

Yes it it... was. GSA 5speed + BMW. There is quite some of those setups
in 24h race. Some street cars are existing too. One UK car owner I asked
to introduce his project here, but he didnt think that its Snail enough...
