"easy" engine swaps

as you know some cars will take other engines.
a couple of my friends drive swapped engine cars.
my question is do you know of more different types of easy swaps..?
i am not talking about a v8 in a hijet or something i am talking about relativ "easy" swaps to do in not to expensive cars.
you dont have to be verry specific with your answer... just a sentence like below is fine.

charade  (G200; 1993–2000)        1.3 16v manual--------------1.6 16v applause/gran move (realy easy/cheap and reliable and fast)

mini wil take a honda vtec engine with a conversion kit
cuore l701 will take subframe+engine from a 1.3 sirion

i forgot the hijet 1.3 16v----- 1.6 sportrak/rocky/feroza swap

A lot of honda engines are easy to swap between cars and there are companies who sell the engine mounts off the shelf.

Seen quite a few c20let swaps into various vauxhalls- Corsas, Novas, Kadetts, mk2 Cavaliers etc etc
