Can you put a blow off valve on a 90 Honda civic without turbo?

Answer:
No, without a turbo, there is no blow off valve. However, if you really wanted to, they have fake blow off valves for sale. These mimic the sound of a blow off valve. It would be an absolute waste of money, but hey, it's your money.
