You are definitely going to need an upgraded fuel pump at the very least. I'm not sure if the stock injectors are going to flow enough fuel to make running the N2O safe. Hopefully someone else with some clue about how to calculate such things will jump in and give you some more directly applicable advice.

Well he does want to run a wet shot, so the injectors themselves are not an issue. I would definitly be careful. Lowered compression if you use it often, and maybe even something that retaards the timing when you hit the "gas".

Do it right, and its not an issue. Its just that people hardly ever do nitrous correctly.

I'm planning to run a 35 nx shot on mine, I just haven't gotten around to mounting the solnoids. I'm not too sure if the standard nitrous equasion works on turbo cars, but on a NA car they say the max you can do is 50% of the stock HP but most of the n20 manfuactures recommend around 37-40% according to there jetting charts. I ran a 75 shot on a JDM H22a in my Accord and never had a problem and I'd gone through around 6 bottles. The motor is rated at 200-210hp and has 10.6:1 compression. Because of the turbo and me not being totally sure how that reacts with the N20, I'm being on the safe side and running a 35 wet shot thats activated only at WOT by a microswitch.
