Just pay attention to my thread, and yes it will cost more than a basic S13 SR20DEt swap. I'll be spending close to $1000 in just putting it on the dyno so my tuner can change cam settings, create maps, and get it just the way I want it for competition. Seriously if you started with a KA24E (single cam) and you're asking about a frankenstein NA engine build, you're not going to be able to do it properly. Just swap in a KA24DE for now and enjoy the car. Also any shop can install and do wiring, when you spin an engine above 8K things get hairy, ask some honda guys about their local shop experiences and how long their engines lasted and made power before things went south due to someone sayin' ya I can do that!
