I can tell you for certain it wont bolt in directly, its to wide like an h22. SO you will be banging fender walls. also i dont think any head will swap onto it except the accord sohc vtec head thats it. you wont be able to use the civic axles. I think you would have to use LS axles but im not sure. as far as wiring im not too sure...But since your car is alread vtec i think the wiring would be fairly similar bhut not exactly the same.....why do you want to put the accord motor in the civic????
