How do you mate two engines to one gear box?

I was on BAT and some VERY adventerous person decided to scale a 1:18 replica into a full on 917 with opposed Subaru Tribeca engines to make the boxer 12. question is, if the cracks are facing each other, how do they put power to the transmission and wheels? Is there a "gearbox" (I know that isn't right but I can't think of the technical term) that makes two right angles and then the shaft runs to the gear box? Also, how do you use a Tribeca auto transmission as a rear transaxel? I'm so confused by this home build.

Two engine cars I've seen before have two gearboxes.

Don't know why you wouldn't include the link in this post?!

Since they're supposedly connected at the crank, pulley to pulley, it is obvious that one motor spins the opposite direction, with the transmission mounted normally behind the rearward engine.

It's also not running at all, so this only theoretically works.

It would be possible for two opposed fore-and-aft engines to drive the same ring gear, if that ring gear was then driving a transverse transmission. Possible, but insane.

Two boxer engines in line? That'll require some work. I think the easiest way would be to simply ditch the transmission and fabricate a shaft that connect directly to the front of the other with a shaft.

But the long route could include actually making them into one, with only one timing belt (I have no clue about Subaru engines), with the valves timed so they fire all correctly to act as a 12 cylinder engine. That'd be ridiculously awesome.
