CG13/10 on a '88 MICRA 1.0 GL (sock purpose)

Hi guys
I have a '88 MICRA 1.0 GL and my engine just broke... I'm thinking on putting a cg10 or cg13 but I don't want to tune it ( at least for a now.) and I don't want to spend much money so with that being said. what I need to do to put a stock cg13 or cg10 in a Micra without spending much money.

thanks for your opinions guy's
king regards.
