ok if you know what kind of model civic it is like ex,lx,dx. if it is an ex then you have a sohc vtec if it is a lx dx then it is a sohc. It you dont know what type model civic it is then take a look at the door handles if they are black (not painted) then it is a dx, lx. If the door handles are painted the same color as the car then it is a ex.

yes there a plenty of bodykits and mods that you can do to your car

yes it would be better to swap also you have the easiest generation civic to swap. but a swap is way more then just pocket change. but it is all in what you want for your car.

hope this helps you out
