if i where you i would just go with a s13 with a ka in it... then along the line you can either buy another ka block and go ka-t or just use the ka you have now and get a decent amount of power out of it with small mods and at the same time save up for an sr or something... i mean you really cant be to different with a swap everything from a-z has been swaped into a 240 small blocks, bigblocks, roterys, vq35 , rb26 the list goes on but it all depends on how big your wallet is it took me a year to do my sr20 swap but thats mainly becuase i did alot of research on where to order my motorset from as well as the parts that i waned to order you can go ebay with your parts but i didnt want to go down that road becuase alot if people i know who go ebay with parts the shit breaks on them... a Ca is a good motor but it deff lacks power .... to me and im sure alot of other people its a pointless swap butif you have a thing for ca's then for for it!! you say your going to be useing your car for daily driving but we all know that you mostlikely will evolve from that and either will be trying to get your car sideways or you will be wanting to go fast .. just do alot of research on what you really want to base your car on and go from there you will prolly be jumping around with differant swaps and ideas untill you find the one you want to do
