Ok ..I have had nitrous in my last 4 or 5 cars. I have used/dynoed most of the kits out there so ill throw in my 2 cent. First off i have to say , every zex dry kit i have put on a car has run lean. I have seen 3 cars all had the kits installed right ......Every time we would go to tune it and end up with the 75fuel and 55nitrous{yea dry kits have a fuel jet}and still run lean on the dyno. Now i got a NOS dry kit and put it on my old lude, went off to the dyno with a hand full of jets for tuning. I had it jetted for a 55 shot and stock fuel system. First pull it put down a 40hp and 60tq with a VERY safe air fuel . I used the kit for a year no problems! I also have had 4 or 5 n/x kits . They work VERY well if you are carefull and know what you are doing. People say wet kits cause nitrous back fires...Well i used to launch my old 97 civic with it armed , it even fell to like 2k 1 time! Never had a problem . Just dont arm it and try doing burnouts or spinning tires . Thatll cause it to pool and boom! I have also had the n/x kit on the dyno and got 50hp and 65tq out of a 55 shot to the wheels! I say start with a good dry kit HAVE IT TUNED and have fun for a while . As long as the air fuel are ok youll have a lot of fun with it .....A really good all motor build with a large shot of nitrous is deadly on the track.....No lag at all with gobs of torque...Anymore questions just ask..If you need help putting it in ill help you ...Dont pay anyone..
