Im currently looking at a zex kit, mostly because i have heard they are simple to install.I was thinking that they cant be that different ( zex v.s nx ) etc. But i was wondering which kit is the best for the money. Im looking to run a pretty much stock setup up now on a d16y8. I heard that jkan when he has his zex beat bolt-on itr's, stock wrx's,and chipped 1.8t's.I really would like to know if nitrous is a good way of fi for me.Most of my races are from a 40 punch. I rarely go from a stop.Im looking to be a little bit faster than a stock wrx, bolt on itr and i would be very happy.Any comments on how i would do against them, or if this is the right kind of forced induction for what im looking for, is welcomed.
