ive heard of a daihatsu engine fitted in a mini before

if it is a cb26 or cb50 i wouldnt bother
it would depend on how much work you can do yourself, look at how much it would cost to rebuild a "A" series motor at a specailist workshop, if you can install a fresh low km jap engine for the same or less cost it may be worthwhile

This is the key point. If you're like Paul and very capable then by all means go for your life. When a man knows what he wants and how he's going to go about it and has in his head the exact result he is going to get - that is what you need.
When i read two lines though i am going to assume the worst that this person is young, relatively new to mechanics, wants more power and wants it done cheap. So with little or no knowledge this person wants power, they also want it now and they want it cheap (dont we all). Not Saying you are this Ralph, but that's the impression i'm led to make when you give us a few words, it shows you can't be bothered to seriously construct a question and give us some information and background about yourself and want you want, to work with.
Goodluck with whatever you choose to do
