F/S Complete Zex Dry Kit nitrous Oxide

Price dropped to 325.00 shipped! Dropped 300.00 Shipped this is a great KIT! some one buy it just sitting in the garage!



I took pictures with it on the car. Will take it off once someone purchases it.
Up to 75 shot....

Selling for 350.00 All you need for this kit is the Nozzle that go's in the the throttle body with the line. Its 25.00 dollars on zex's website...


Comes with 15lb. Bottle
All lines and solenoid pack. You need to purchase a new Nozzle from zex for 25.00 and a 2 dollar switch.
This dry kit put my automatic maxima with just a y pipe and intake in the 14's
I"ve run a 14.0 at 100 mph on street tires with a 65 shot. Without zex I ran a 15.3 at 92 mph
Done multiple runs between 14.0-14.2... If you were to get better tires than I had you would be in low to mid 13's...
I take paypal and have a great trader rating. My email for payment is austin77242000@yahoo.com.
Take it before someone gets it.

This kit almost sold. I had it held for someone on here. He found the same kit in his town. So its still ready to be shipped.

 

Bump anyone

 

Gluck dude. If only this was a 100 shot..

 

I am in the market to buy a kit and was mostly looking at wet kits... How do you supply fuel with the dry kit?

 

s
the instructions tell you how to install the zex kit which you split into the fuel line... which in turn routes thru the soleniod pack. Depending on how much fuel pressure is in the system you are safe up to a 75shot in the 4th gen.

 

You are describing a wet kit.

 

No I'm describing the dry kit. I have the instructions and have also installed this kit on my maxima.

 

the dry kit has the nozzle in front of the throttle body and thus supplies the nitrous through that. a wet kit actually has the solenoid connected to the fuel lines. correct?

 

well as far as I know, both dry and wet kits have nozzles before the TB, but the wet kit has both a nitrous solenoid (nozzle) and a fuel solenoid (nozzle) that comes from a T in the fuel line. I'm just not sure how the dry kit provides fuel as the reason it's called "dry" is because it doesn't add fuel with a solenoid like the wet kit does.

 

Nevermind, I got the answer I was looking for.

As I thought, Timz96se is completely incorrect. In a WET nitrous system, extra fuel is introduced with a T in the fuel line and put into the intake manifold along with the nitrous.

In a dry nitrous system, extra fuel required is introduced through the fuel injectors, keeping the manifold dry of nitrous. This property is what gives the dry system its name. Fuel flow can be increased either by increasing the pressure in the fuel injection system, or by modifying the vehicle's computer to increase the time the fuel injectors remain open during the engine cycle. This is typically done by spraying nitrous past the mass airflow sensor (MAF), which then sends a signal to the vehicle's computer telling it that it sees colder denser air, and that more fuel is needed. This is typically not an exact method of adding fuel. Once additional fuel has been introduced, it can burn with the extra oxygen provided by the nitrous, providing additional power.
Dry nitrous systems rely on a single type nozzle that only sprays nitrous through it, not nitrous and fuel. These nitrous nozzles generally spray in a 90 degree pattern.


So with all this stated, are you now saying that you are selling a wet kit? Because if you are putting a T in your fuel line, and running it through a solenoid with the nitrous, then that is technically a WET nitrous kit.

 

Before you come on here and tell me I'm wrong....
What you have to understand is you "T into the Fuel line" then you route the fuel line thru the SMART BOX... Which is called the Soleniod pack on a "ZEX system". It measures the fuel pressure in the system by routing it thru there box. Also the nitrous line coming from the bottle is routed thru the soleniod pack and then routed to the front of the Throttle Body. Which is only one nozzle that provides the dry nitrous to the intake manifold. I never said you have to provide fuel thru the throttle body. I said you have to route a fuel line thru the soleniod pack. I understand you may have misunderstood me. Because I wasn't very clear.

 

Here is one answer of why there fuel line is routed thru there soleniod pack.

What makes our dry manifold nitrous system work so well is that the fuel control circuit
references the actual bottle pressure to determine enrichment fuel needs. The other kits on the
market use fuel regulating systems that ignore bottle pressure entirely, thus producing a constant
level of fuel enrichment no matter how much nitrous is really going into the engine. Ours, in
contrast, is self adjusting within its operating range. This difference in approach allows our kit to
have optimum nitrous to fuel ratios at all bottle pressures. That is how we can give you more

horsepower per pound of nitrous and less chance of engine destroying detonation

Thanks for posting more info, I had actually researched the info and have been too lazy to post it up.

The only reason that you do a T in the fuel line for the "smart" dry system is so that it can monitor the fuel pressure while it increases/decreases the pressure via the factory FPR in accordance with bottle pressure.

When I asked you how it supplied fuel, you could have simply stated that the zex "smartbox" increases fuel pressure on the FPR whiel monitoring fuel pressure and only put a T in the fuel line to monitor the fuel pressure.

Sorry for being abrasive with you, but MOST dry nitrous systems are pretty unreliable and sort of "ghetto rig" the fuel addition in some way or another. It's good to see that zex has done it differently.

PMing you about your price, though... just as an FYI, not going to post it in open thread in respect of you as a seller.

 

Pm'ed you back.

 

Priced Dropped! 325.00 shipped

 

bump still for sell

 

bump to top

 

BUMP !Anyone I still have this kit price dropped to 325.00 SHIPPED!!

 

Bump 300.00 shipped anyone ?

 

Bump 300.00 Shipped Awesome kit

 

Bump anyone want the system ?

 

Almost to my nitrous price point....

 

Bump 300.00 SHIPPED dont pass this up
