Sales pitch: <snip> See my book in sig on how to do it! <snip> or even a smaller engine, like the Suzuki three-cylinder.
I've done a nice rear engine mount system for the Suzuki/Chevy/Geo Metro engine, it fits on a 2" square tube subframe, if you want to connect with me off list I'll send you the drawings and/or parts. They're quite light (14 gauge mount on 16 gauge tubes), they could be made more simply (less triangulation) from heavier stock, but then I think then you'd need heavier tubes to keep them from tearing out in an accident--and let's face it, one of the big issues with midi design is keeping the powerplant out of the cockpit in an impact. Since my background is aircraft, I'm using 30 Gs as my target...I don't know if there's an SAE figure for rear engine mount strength, so I go with what I know, and for a 30 G engine mount this is pretty dang light.
