yeah, exactly. entirely custom mounting. by that, i mean more than just moving engine mounts around. the guy on 3geez who had it done said something about crossmembers being moved or something of that nature. and you'll have to find axles that fit. then you have the wiring nightmare. it's doable, because it's probably not much different than wiring up a vtec b-series and that's been done. even a write-up about swapping in a b-series w/o a mount kit. and i couldn't imagine an h-series would be much different. but you may also have to adjust suspension, especially if it's lowered.
