i hope you're kidding.
With a little creativity, I'm sure you get an H22 to fit. They are cheap & powerful.
Not at all, a few custom mounts, easily done with the right tools. I've seen a lot freakier things done than that. An H22 puts out a solid 200HP & you pick a used one up with a tranny & computer for about $2,500. The time will be in butchering the wiring harness, but that still aint too bad. Most engine swaps require splicing of the harness anyway.
