Hey dude! I just bought the Zex kit from my buddy dealer (we hold a tight relationship since i send him buiz for performance autos and he sends me the same for harleys)
i have a 2k2 max 6 speed and the the jets are offered at 35,45,and 75 hp increments. DO NOT GO WITH THE 75 FIRST!
play with 35, and 45 first. i chose the 45 hp gain since i can still control the hp ratio and the wheels dont spin out of control.
Be Careful! Make sure that it is installed by someone who deals with NOS not you! In case something happens to the engine it is easily removeable and no one knows there was one in! this is a system that hides well the ZEX system is the best NOS available to Max Owners period! plus i like the way it hides in the trunk; i am the type that never tells anyone about the system unless here.
My bud and I have an agreement to not say anything
most of all don't abuse the system and use only when you know you might be beat. It's awesome when an M3 pulls up and threatens you and you floor it and he pulls away and then you flip the switch (with understanding) and you pull right up to him. He will win after 115 mph but with disgust by buying twice the dollars(and the pull is slow..............) be careful but the upgrade is awesome!

i heard something has to be done to the voltage or something to the car for the system to work properly... can anyone elaborate more on the subject and what exactly has to be done?
thanks
-danny

 

danny, you have to keep the car stock with the exception of a k&n filter
the voltage regulator is fine no exhaust upgrade, cold air intake, chips; XEX MADE THE SYSTEM FOR STOCK UNITS THEY EMPHASIZE NOT TO ALTER ANYTHING! hence i kept all stock including the ignition, regulator and exhaust
try before you buy

 

keep your car stock! jesus~! don't mess with voltage regulators or exhaust and chips
if you are talking to people who tried to install them they will reply this way
an old saying in the performance buiz: Follow the Factory
mine is running awesome;
want to elaborate? i am willing

i remember reading in the past that the voltage that the car makes at WOT is not the amount that the zex kit needs to read to work optimumly and that something had to be done to get it to the right voltage... i cant find the thread now... but i remember i read it a while... u prob just dont know what im talkin about... but i remember something like that for sure... nothing to do with the mods i have.. it has to do with the way the car is stock...

 

The TPS voltage is what you are talking about. When ZEX first said that they had a kit for our car that was not really true. But since then from what they say it has all been fixed. I don't really talk to them anymore, after a dispute on the phone.

The TPS voltage used to have to reach a minimum of 4 V and the max at WOT was maxed out at 3.8. So in order to get it to work you had to adjust the TPS. DO NOT DO THIS, IT IS NOT A GOOD THING AND IT MAKES THE CAR RUN LIKE CRAP! I did this and got the ZEX to work, since then I have gone back and reset it to oem standards and I plan on sending my box off to get reconfigured to the setup of the new ZEX kits that allows you to set the ZEX kit to your TPS Voltage rather than changing the V on the car.

Once you get the kit working it is great, and you will love it. And like I said they say that they have made the changes since I bought my ZEX kit over a year and a half ago

Hi guys, how much does the Zex 45 shot cost and where to get it ? What about my existing mods, do they have to go or can I keep it ?

Thanks for the infos.

Cheers

Glad to see they fixed the TPS problem.

What kit # is for the Maxima?

Also are you using their (ZEX) plugs?

 

Wow...Now I want Zex kit! :/

 

yea which is the kit # for the maxima and can i make any zex kit work on my maxima like if i take a used one from someone that had 1 on their honda? please let me know asap cause im trying to close a deal
thanks

just wondering......how much did you pay for it?
and where'd you get it from? I'm considering getting nitrous myself but not seriously...........yet

 

Are any of you guys planning on upgrading your stock fuel pump?

 

just got off the phone with ZEX
the kit we need is the 82011 kit
it usually says everywhere that its for honda acura and not for nissan but he said that is wrong it will work for nissan... they also have a nissan specific kit which is the 82014 and he told me that it is identical to the 82011 except the case that holds the NMU (nitrous managment unit) is upside down... meaning that on one it says ZEX from left to right and on the other it says it from right to left... so he said they are identical... the reason he told me to get the 82011 is because that is the one that is most comonly held in stock by store and usually no stores have the 82014... and yes he did confirm for me that the TPS voltage problem they had before is now fixed and the system actually learns the voltage of your car and adjusts itself to it... woooo hoooo im excited looks like im going with zex... and pretty soon too!


and yea kev im looking to upgrade my stock fuel pump because i want to run a 75 shot... why do you ask?

 

Don't want any blown up motor stories on the .orgy.

Which pump do you plan on getting?

 

http://www.autoperformanceengineering.com/ has the cheapest price Ive found on upgraded pumps...

 

i dunno kev what u recomend? i know zex themselves have a add-on in-line fuel pump... it seems real easy to install but it costs almost like $190... so what would u recomend? most people on the org got the walbro right? how much do those go for?
thanks

Is that a GS400/430 or 300? BTW, your driveway looks AMAZING

 

Check this out. Too much of a good thing can be bad.

GS430

thanks

 

I would get the Walbro fuel pump, but I don't know if it fits our car.

Check out Matt's link.

 

Is anyone upgrading to the ZEX plugs?

I wonder if they preform bad when running NA like most colder plugs??

Thats the kicker about NOS, the plugs you need to run NOS usually decrease your performance when not on the juice.

ZEX just came out with a lot of extra's that were previously not availible but they are expensive.

I think you can get the NOS kit for alot less? The benifit of the ZEX kit is that it used TPS voltage instead of a microswitch and it uses bottle pressure to regulate Nitrous. (but not sure how they do this)


what wire is the TPS that you tap in to?

 

Well I was running the ZEX plugs for all of about a 3 months or so and then I realized that, that is where I was loosing my NA power. They work great with the nitrous, but your best bet is to get some NGK's and just gap them to a colder setting. And yes the Zex kit reads N2O pressure, Fuel Pressure, and TPS voltage before allowing nitrous flow. Probably the safest kit for the money!

 

do you have pics or could you explain what wire you tapped into for the TPS?

 

damn......that guy is probably f*cked!!!!

 

TAPPING INTO TPS:: All you need is a volt meter. If you look at the back side of the TPS you will see that it has two sensor like plugs-each one has three wires for a total of six wires-. You are going to have a number of different readings from these wires, the one that you want is the one that changes as you give your car throttle and that reaches around 3.9 V at full throttle. So turn the ignition on and find the wire that as you rev the engine the voltage increases and then simply t-tap it! And the only other wires that you have is a power and a ground. Then hook up your fuel pressure line and nitrous line and run the wires to the cockpit for the arming switch and you are ready to GO BABY GO!~

 

Ok i gotta few questions since i was thinking of ordering this kit. My friend has the NOS kit and is running a 100 shot. He has a RPM window switch that activates the NOS during WOT from the rpms of 3500-6400. Does the Zex kit have a system like this? Does the Zex kit just engage at WOT? I think that if it does, traction would be a HUGE problem. Also where is the cheapest place to buy the Zex Kit?
Thanks

 

I've been told you should get a fuel pressure regulator if your planning on getting NOS. However, there is a concern the fuel lines might not handle the higher pressure.

I wonder if you get 10% larger flowing injectors(RC Engineering), the Warlbo fuel pump, and a fuel pressure regulator what kind of shot could your fuel system(NOT engine!) could handle? 100hp?

 

okay i am running the nos zex system with factory options i will report soon; so far it works well with a 45jet/hp boost
I ran my co-workers wrx sub and he had a half car length lead at 60 then flipped the swith and the pull was like leaving an 8 sec car....

nvmymax2, I found the 6 wires, shouldn't we all be tapping into the same wire for 5gens?

I'd hate to strip each wire just to get a reading? which wire did YOU use?

rwbro719, what wire did YOU tap into?

 

Hi guys, what would be the ideal ZEX kit or NOS kit to buy ? that would be cool to know exactly what it require to make a safe and pro install. Zex sell a kit but as far as I understand it's like not every thing is include ( just the basic ) ie: gage, pressure regulator, fuel pump etc. Let me put a that way, I dont know much about NOS, why not having some sort of write up witch would tell us what to buy and please dont forget to put everything. I hate when I buy something and I found out a week later that something is missing to make it optimal, or the guys tell you oh, you should have bought this or that, grrrrr.


Cheers

Before NOS make sure your car is in good running condition, then beef up the tranny (VB mod or clutch)and take care of any TSBs.

The NOS kit for our cars is #5124. The basic kits let you run up to about 50 shot depending on what other mods you have on your car.

Higher than that you will need gauges, fuel pumps, spark plugs...etc.

Nitrous is more of an art than a pure bolt on. The "basic setup" will depend on who you ask. Some will say get gauges with any setup and some will say only if you are running over XX shot. I bet no 2 people have the exact same setup. Read as much as you can and start pricing parts and then hit up the forum when you run into questions. It all depends on how much you want to spent. (basic kit ~$400 to full setup ~$1500+)

 

Very GOOD reply! Couldn't have said it better.
