engine swap

[LYLMIK]

hi guys!!!

i am new in the whole car modification sector, just wanted to ask for a bit of help.
i have a honda crx '91, since the australian car standards suck they downgraded the engine to only 113hp.
since my mum is driving faster on her pushbike, i want to put different engine into it, but really unsure about the size/fit difficulties.

following possibilities were suggested, if someone would say yay or nay on the types that will fit in it would be really apperciated.INTEGRA
