OH and Nissan is not the only Automotive company that does this BMW does it as well on their inline engine setups.
With that said indeed the mounts I sold were offset. Is it super critical? Well they design these things for passenger cars and some kind of longevity, as well as comfort i.e. less vibrations and whatnot.
We are basically putting or cars into a performance segment that usually throws comfort out the window in favor of better performance.
Given that, not having offset mounts is a world ending issue. You can run them and their will be no problems.
I see no problem with it at all.
Oh I should add, those mounts look very well designed and now that its been cleared up that they do not have a solid shaft or connected metal in them, they sound great.

He is talking about the bolts being offset. Not the engine being TQ angled.
Nissan angles their motors mainly for oil drain back. BMW angles their motors to the right for packaging. The Chrysler Slant-6 was angled to the right for the same reason. To the right would make tq shock worse by your math.
Most engines can flip themselves over. TQ angling does little to counter act that load. It's mostly done for packaging and a little for oil draining.
