With 65 shot I ran a 13.838 at 102 in a Front wheel drive 6 cylinder, most Cobra mustangs that night were running 14 flat. :) Intimidation: I hit the purge valve next to a 2002 Trans Am Ram Air who was laughing at me when i was reving to him, after he saw that he turned his head and switched lanes to get away. lol.

Filling up bottle is not to bad. But you feel naked when bottle is low.

This product as you have read is to easy to install, I thought I did it wrong or that I was missing parts. Simple Fast and Easy.

-Easy install. Took me around 5 hours, mostly drilling. I didn''t have the right bits for the job. -Small enough to run on stock internals. -Power gains. -Price. -On/off power -Activation at WOT.

-My new bottle had a leak in it. Wasted $50 worth of N20. -Crappy customer service. Techs just reads off the instruction, has no real knowledge of install. Took forever to get my bottle back. Poor packaging on their part sending it back, resulting in a scratched bottle.

I was concerned about putting nitrous in my car at first. But after carefully reading everything I can find about it, I was sold on the zex kit. I haven''t tested it at the tracks yet, cause I put it in right before winter. But I tested it pulling out of the on ramp. With a 55 shot I wasn''t really impressed with 1st and 2nd gears. But once it hit 3nd it pulled like hell. My head snaped back to the sit and I got the adrenaline feeling back, like when I first tested my GS-R. I can''t wait till it gets warm, so I can get my timpslip. I''ll report back when I do.

EASY TO INSTALL!!! Nice purple powder coated bottle. Nitrous controller is a nice neat box, no solenoids to deal with.

Dry kits like this can usually only safely go up to 75 HP on a 4 banger. Depends on your stock fuel system, but so does every other dry kit. Go with a wet kit if you plan to pump over 100 hp on juice.

I installed it myself in about 4 hours. I have it jetted for 65 hp and it works great. Nitrous is only activated at full throttle. I havent tried the 75 shot setting yet but at 65 hp the engine (DOHC Quad4 2.4) seems to love it. Will work great on any car as long as you have a voltage regulated throttle sensor. Call Zex for tech info, they are very helpful on the phone.
By the way the kit I bought is a universal kit and it still installed flawlessly.

My car pulls harder than an Integra GSR now :) Costs way less than a supercharger, turbocharger, or engine swap. Can be turned off.

The bottle needs refilling, which is a drag compared to say buying a turbo.

This kit was fairly straight forward to install. The instructions were somewhat broad in my opinion, but I was still able to get installation done myself despite some of the vagueness. IE: Remove drainplug in trunk. Yeah...that was fun looking for a drainplug. I finally got frustrated and just drilled a hole in my trunk, far, far away from the gas tank of course.
Once installed, and testing time came, the kit did not disappoint. At 65 shots, which is the highest jetting I have used, with a AEM Cold Air Intake setup, DC Sports 4-1 Ceramic Coated Headers, AEM Catback Exhaust system, my car pulled long and hard like a 6 cylinder, while in reality, it is only a 1.6 liter 4-banger.

easy installation, cheap horses, bragging rights.

have to fill the bottle.

Kit was easy to install, easy to use and dropped my 1/4 mile time 2 seconds. It's great! ALl the other kits were very expensive and were so involved. The Zex kit only has 3 wires and a few lines to run. The best part was the customer service, I called them 50 times before I even bought the thing. The answered all my questions and were very helpful. Now my normally slow avenger is a rocket!
