hey,

anyone in there have a Zex kit? i talked to my friend tonight with a 2000 accord 4cyl 2.2vtec an he said that its completely safe to run it... he runs a 65 shot... not now but during summer so i was thinkin about getting a kit... what effects will it have on my engine? and do u guys think its a "smart" HAHA move?

also... do you need the zex spark plugs?

ive heard that nos will make your engine wear out like 3 times faster or somthing

Sigh...

Nothing is completly safe.

READ this and LEARN. DOnt listen to anything these tools have to say about nitrous.

And ZEX spark plugs SUCK HARD. I melted one of their plugs on a 50 shot. POS.

READ!

u dont know s**t about nitrous...and u wanna run one? u'll blow urself into pieces. do some research brothda man

that's why he's asking questions. don't flame him unless he asks something stupid...

i.e.- "should i get altezza lights?" [IMG]i/expressions/laugh2.gif[/IMG]

j/k to the altezza people... get what u like...

it's safe if you don't use it like an idiot
there are a bunch of people on this site who run anything from a 35 to 65 shot
and you don't absolutely have to use the zex nitrous plugs but it's "safer"

heh lil too high there...just want u guys to search for nitrous posts in the past beforea asking thats all....

 
Rep Power: 0

i think that its going to be safe if u use a 50 shot of any kit, and for the spark plug jus go whit the IK22 denso, u can find it in autozone i think, correct me if im wrong...... good luck .............


everyone born knowing nothing dont flame pls... if u know something that i dont know or we dont know just explain it ...................

I agree with Joe 100% that nothing is completely safe, but yes nitrous will wear out your engine faster.

the kit i was thinking about guys was one my friend had... that you arm it and when u FLOOR it then it puts small amounts of N02 into the system... then more an more an more not like "fast an the furious" "nos" where u just push a button an ur tires squeel[IMG]i/expressions/laugh2.gif[/IMG] but ya thats why i am doing research JARULE... blow my engine to bits "he has enough nos in there to blow himself up" anyyways tell me if this kit is what u guys were talklin bout... holla back

IK22?? WTF?? Those spark plugs are wayyyyy too cold, IK20 at most.

I got mine from groupbuycenter.com for $43 shipped.

 
Rep Power: 0

ik20 is stock temprature. if you run nitrous, typically you need colder plugs, hence the need for ik22's. i think joe said something about using cheap NGK's rather than iridiums because they perform better under nitrous despite the shorter life otherwise

IK16 is normal temperature.

IK 16--for stock
IK 20--Bolt on's
IK 22--Nitrous

About the bullshit being thrown out about sprak plugs...

Electricity, by its nature, flows along the path of least resistance.

What does this mean exactly? It means that, generally speaking, multiple grounds such as the BOSCH +4 and Zex plugs are useless.

Why? Simple.



A. terminal
B. ceramic insulation
C. center electrode
D. gap
E. ground electrode

Say this spark plug has multiple grounded electrodes, like a +4.
Now say, it is in an engine and is about to fire.
The spark energy flows down the center electrode, out into the gap and onto the closest (remember "path of least resistance"? ground.
This pattern will then repeat over and over for the entire life of the spark plug. That means the spark will hit the same ground EVERY time unless the grounding becomes damaged or so corroded its proximity to the center electrode is no longer enough to make it the least restrictive path for the electricity. In that case it will move onto one of the other grounds.
And that brings us to the only plus of having multiple grounded electrodes. Fact of the matter is though, unless you dont plan replacing your plugs between 100K mile intervals you will never need the extra grounds.
This is one of the reasons why cars advertise "no tune ups before the first 100K miles".
Personally, because I run nitrous, I change my plugs with every oil change.

The same goes for platinum and iridium plugs. These dont offer better performance. They just last longer. Another "100K mile tune up" deal. Under normal driving conditions the center electrode made out of these harder materials will, of course last longer. Because as we all know its so costly to change spark plugs at 60K miles, this is a must have, right? Pfff.
The ONLY reason why dealers recommend these plugs and why manufacturers put them in their cars is for that reasons and that reason alone.

Now, for high compression, turbo, and or N20 applications PLATNUM AND IRIDIUM plugs ARE NOT GOOD. The center electrodes will actually crap out much faster then your standard core electrodes under those conditions, especially N20 applications. Ive seen many a nitrous'd car running Denzos pop a plug. Trust me on this one.

And for the record ZEX SUCKS ***!!!! Yes, thats right. ESPECIALLY their spark plugs.
How do I know this?
I bought a set. Not only are they 2X as expensive as the NGKs I use now the crapped out on me.
Three sub 15 second runs on brand new Zex plugs (on just a 50 shot mind you) resulted in one SEVERLY melted #3 plug. And I mean SEVERLY. All 3 ground electrodes were carbon coated, the center electrode AND the protective ceramic coating were melted and vaporized completely through. Thankfully there was no engine damage, but thats not the point. For a full year after that I ran the EXACT SAME set up with my NGKs, and had NEVER had a problem. Not once. Whats that mean? Its obviously not a mechanical or installation problem with the nitrous or fuel injection, rather its solely the fault of the plug.

PIECE OF S**T

Plus Zex plugs are made in France. That should tell you enough.

Oh, and what do I reccomend for Nitrous and turbo applications? NGK-BKR7E (8E's for apps that call for 2 steps colder over stock for Si's) thats what. 2 bucks each (high end) and are t3h b3st.

Not to mention that because platnum and iridium last so long, they also retain FAR more heat then your average spark plug. What does this mean> It means when there is extra heat generated by FI or N20 the ground electrodes will retain that heat and if used for a prolonged time eill be hot enough to predetonate the A/F mixture resulting in a blown engine.

It don't matter that they last long, it's the heat range that matters when it comes to engine mods, nitrous, and detonation. Oh yeah, engine compression, timing and octane count for something there too.

NGK-BKR7Es

you can get them from summitracing.com or sparkplugs.com for cheap (1.50 each or less)

Yes, you need to indeed.

Nitrous oxide injection, supercharging, or turbocharging can give the owner a substantial boost in performance.

Unfortunately, this increase in performance can sometimes come at a cost. Many owners are unaware that whenever you select different cylinder heads or whenever you add a turbo, blower or Nitrous kit, a different spark plug will be needed. The added cylinder pressure that is present whenever you raise the compression ratio requires:

1) a colder heat range spark plug,
2) a smaller gap to prevent extinguishing of the spark.

A good rule of thumb to follow is for every 75-100 hp you add, you should go one step colder on the spark plug's heat range. Since the added horsepower brings added combustion chamber heat, the colder spark plug will remove that extra heat and help prevent detonation and or/pre-ignition.

This has NOTIHING to do with the center electrodes composition. "colder" plugs are colder because of the ground electrode(s) as well as the ceramic coating.
You could have a colder iridium plug, but the fact is that because the iridium is so hard its heat retention can and wll cause predetonation.
Also, I never said changing you spark plugs is the end all and be all of preventing detonation, so I dont understand your point about bringing up compression ratios.
