I have checked through your tech section and couldn't find anything so 2 questions.

One could someone give me a basic rundown of what is involved in putting a z18T in the above mentioned vehicles Engine mounts/ Cutting of stuff/ Misc Anythin really.

Second one, can this then be engineered in NSW

Thanks

pretty much the same as for fitting the L series in a 120Y. There's heaps of info here about that.

Once the 180B x-xmeber is bolted in, mounting the Z18 is the same as dropping it into any othe L series Datto (1600, 180B etc) which I believe is as simple as swapping engine mount brackets from left to right sides on the block.

Fitting it to a 1200 is a whole different ball game, and is custom work from start to finish.

i suggest u just sell your z18turbo or scrap your idea of using one, and get a ca18det they are better engines, and u can get maddat crossmembers for the ca-1200 conversion
