Deathrat - where did I ever say where to put nitrous in a turbo setup. Noone has ever asked that question. To ansnwer this, in a turbo setup you have to put the nitrous before the MAF is it'* dry (bad idea) in any turbo setup or any setup period so the computer can read if there is more incoming air. In a wet setup in any forced induction car you do NOT spray through the MAF. It is not necessary since you are doing it manually by spraying the fuel and nitrous yourself so you don't want to the computer to add even more fuel and go rich plus you don't want to foul up the MAF sensor with fuel. And you NEVER inject nitrous into a turbo, crack city and failures will occur. The turbo is hot on exhaust housing from the exhaust, they usually glow. The compressor side is also hot from compressing air so not a good idea to "instanly" cool it with nitrous, will cause cracks even though its an aluminum housing, can't take that temperature change that fast.
Jeffery - IT'* not a problem to really use a small dry 55 shot. The Zex system is progressive and will allow the computer to adjust and you will have some saftey features. But!, does not guarentee something cannot go wrong. But using a 55 shot reduces those chances to much less.
