Re: New Guy Nitrous ???
don't need a purge or a blanket. you do not need a blow down kit in the trunk but it is a good safety Idea any way so get it for $20-$30 it is worth it. as for the rest make sure it is plumbed with no leaks and make sure you flow test the fuel side after install. that is all there is to a 125 shot setup.
