I would twin it too. If you can fab some stuff you can build a kit for around $800 plus the turbo.I've already talked with him about it. He said forget the no2 and twin it. I'm just to cheap to buy a charger right now. 500 bucks for a charger in a bottle sounds better than 3500 right now.
I always wanted to put nitrous on my truck but I am afraid to blow shit up
