Yah I know how it works, I've taken several Subaru engines out. However, since the trans has its own mount only half (approx) of its weight needs to be supported. More importantly, the weight, for the most part, is not supported as a bending moment on the block of the engine, as is the case when hanging it off a transaxle, as in a bug. The stresses are mainly torque and some shear. The issue in question is the .. wait what's the issue in question again..? oh yah

,
-I think we both agree that the trans needs to be supported.
-I know some guys at
www.vwrx.com and yahoo groups were having trouble breaking engine mount bolts so use good bolts, and possibly even thread the dowel pin holes to help.
-I would only suggest (based on other people's experiences) that if its used for offroad at all to support the engine underneath
What I meant by "doesn't support the gear box" was, "the gearbox doesn't just hang off the engine with no other support", as in: the whole weight of the gearbox isn't on the engine, and doesn't created a significant bending moment. Sorry, its just thats what it sounded like you were suggesting. I probably could have been more clear on that
If we're still in disagreement, than I agree to disagree

and Hoghead, good luck with the conversion
