Well that kit looks like a bad deal in a box to me, I've seen so many rigged nitrous kits cause engine failure its not funny. A lot of engines with forged pistons and built heads etc need rebuilds every 6 mos to a year running on the bottle. Also Wet or Direct port injection is the safest for nitrous, dry shots can be a lethal deal, and on a NA 7m-ge doing that would be like asking for a BHG or worse, and even a 50 shot doesn't do much, I've beat an eclipse spraying a 50 shot of wet which is a bit better and it did little for that v6 junk he kept up off line and then I pulled away and thats on 10psi of boost alone, I am not a nitrous fan, If I were running a team for drag with a big budget I'd say sure but dude that stuff will cost you so much over time along with the constant refills when all is said and done you could have just done a motor swap or an NA-T conversion. You decide, Spray at your own risk!!!!! I also say if your going to do the nitrous then buy a good kit from a credible source, 85.00 on ebay may cost you 1200 at toyota.
