F4R736 alternative block

[Perth Clio Fan]

So my 172 has scored bores (still running great in the car) and I'd like to get another motor for its block. What are my options? Finding another F4R736 from a 172 or 182 is difficult so I was hoping I could get an engine from more common, less desirable models using F4R's like a megane or scenic of the same era that uses the same bolt patterns for gearbox and accessories etc.

I'll also add that I'm in Australia.

Thanks guys.
