I will be buying the zex nitrous kit shortly for my car and I was wondering if anyone can give me a quick run down on the install who has done it themselves. I am planning on putting it in with the help of my dad and he wants to know whats involved in the install before I buy the kit. So any help is appreciated. Also if Im running a 75-100 shot I am going to get colder plugs and retard the timing. Is there any other safety precautions I should take. Such as a window switch? Any help is appreciated thanks!
