I think that would be ideal - if I can find one. If I can match the injectors to get an extra 7% flow vs. the injectors on the Z7, it might not even realise it's running on a different block
Which leaves the problem of EGR of course, the Z7 definitely has this, but no Aus. Hondas do. I wouldn't be too concerned about it except that I've read that FE goes down on lean-burn Hondas with clogged EGR ports, which implies *no* EGR might be a bad thing.
I'm not in any particular hurry, so I'll probably just lurk and keep an eye on ebay for ECUs and manifolds... of course, getting shipping to Australia is often an issue with this sort of thing..
