My friend is going to be installing a ZEX Kit on Integra soon and has got a question. When installing the nitrous nozzle into the intake tube does it matter if the nozzle is placed before the PCV valve tube that goes from the intake to the valve cover. Will it do any damage if some nitrous feeds through the PCV valve and into the head? Thanks

 

i would put it after just in case.
but i took that tube off anyway. so ?
