-The subaru engine DOESN'T support the gearbox and axles on a subaru car, the transmission has its own mount as well.
-I don't see how it would be surprising if you had a subaru engine in an offroad/baja beetle and just had the engine hanging off the frame horns that the frame horns coud bend/crack. Engine blocks have apparently also broken. If you're jumping a car or hitting serious terrain at speeds there is plenty of force there.
If the frame horns are sufficiently supported (tied into shock mounts, 3-bar kafer style brace at minimum, to at least handle the increased torque) and you use 10-12MM grade 8 bolts to bolt the engine on, I believe this is sufficient. That's my 2 cents... well maybe 3.
