any comment?

 

That forum blasts on every US made kit.

They claim their kits are absolutely perfect.

 

Been using it for 2 years and my solinoid is doing just fine

 

Never had a problem with ZEX, works fine for me... Peace

erm... not quite

i've got one of those kits and it's an amazing piece of kit, absolutely nothing like the nos kit. i think they used to sell to nx until recently, so nx was copying their designs

all they said about the zex kit was about the quality of the solenoid, which is a commercial off the shelf unit.

 

Zex works fine for me.

 

ZEX has worked great for me as well... probably the best kit out there right now

i'm not slating zex at all here, but how are you qualifying that statement?

 

because it uses actuall bottle pressure to determine how much nitrous to feed, plus it only kicks on at WOT, two MAJOR things keeping it safe from blowing anything up. It controlls feul pressure to so everything stays even and you dont' run rich or lean. If you know of another kit that is better then let me know

erm... highpower
works on WOT, lifetime warranty on all products, amazing quality pulsoids - the only solenoids designed to pulse, fuel pressure safety switch, unparalleled customer service, time based multi-function progressive controllers

and how is working off bottle pressure a factor in stopping your engine blowing up?

 

its a dry kit and is not as safe as you guys think. wait until the purple box fails and peace out to your motor. the more simpified wet kits and Direct port kits have less parts to fail and if setup properly are safer.ZEx just has a great marketing scheme that makes people beleive the working of bottle pressure is actually safer.

Tell me what kit has less parts than Zex???

 

Me I've got a NX kit and it's superb.

Really easy to install and set up and looks the part too, which is nice

there are several parts in that purple box you know, plus there is the small matter of uprating the fuel delivery, and accounting for varying this in spraying/not spraying situations

No there isn't alot of parts in that box. Just a chip and a solenoid. That's it. There is no way there are less parts in a direct port kit to fail. Also, Hondata's new nitrous control is perfect for dry systems fuel delivery for spraying/not spraying situations.

If the purple box fails, there is no peace out to the motor. If the box fails the whole nitrous system will go down. There will be no nitrous, there will be no extra fuel, it's only ONE solenoid. What's going to blow the motor? It's the parts in the wet kit you have to worry about. If the fuel solenoid fails, then peace out to your motor with your NX kit. I still can't figure out why everyone thinks there are less parts to fail in a wet direct port. There are MORE parts.

Regulating nitrous by bottle pressure is not only more safe, but more efficient. If the bottle pressure is higher than normal, say if some dumbass accidently overfilled your bottle, the Zex box will raise fuel pressure that much more and prevent a lean condition. When your bottle pressure starts to go lower near the end of the bottle, it will raise fuel pressure that much less, more efficiently burning nitrous by not creating an overly rich condition.

 

so for your zex system with
bottle, crappy solenoid, firing circuit, brass distribution block, n2o injector, uprated fuel pump, uprated injectors, ecu/afc modification

has less parts than
bottle, 2 solenoids, 2 switches, 'fogger' injector


pulling your leg a bit, but you have to admit there is more to it than just what you get in the kit. i take your point about the fuel solenoid being the weak link in a wet system, but i have a quality pulsoid designed for the application, rather than an COTS product , so feel the advantages outway the potential, if extremely unlikely, pitfalls

 

Well if you compare base system to base system, say for 75 shot or less the upgraded injectors and ecu modifications aren't needed. I don't see why a wet kit wouldn't need an upgraded fuel pump as well, it still needs to flow that much more fuel, and also I don't see how a brass distribution block would fail. The solenoid is the weak link in any nitrous system, wet or dry, only wet has two of them. In my opinion both have their advantages and disadvantages, but I would never use a single fogger wet system, only direct port.

Remember though that a basic dry kit increases fuel pressure. Flow rates from the fuel pump will decrease with increased pressure. So a dry kit will always need a pump upgrade before a wet kit. Of course a good pump upgrade is always an excellent idea.

 

ryan, i was reading about mr nitrous wizard, im definitly impressed of how well you stood your ground. He tried to bully his way to the top by saying ive sold 1000's blah blah blah, but in all honestly, he didnt back much up.

No doubt both kits are very nice... but that guy is way too into himself

it's his company, he designed and made the kits, what do you expect?

No wonder, he think his product is best in the world!!

 

can't argue with a 1.3 second improvement in 1/4 mile time with only a 50 shot though!

The increased fuel pressure, no doubt is extra stress on the fuel pump, but I would still upgrade fuel pump with a wet kit no matter what. I wouldn't trust the 79lph pump that comes on most Civics for any type of forced induction. Only the GSR, Type R, and Si came with 135lph pumps.

Same results can be had from a 55 shot of Zex!

 

Check out what those ******** are trying to tell me know they said that no US companies make any good aftermarket parts for Hondas. They are also trying to tell me that a 2000 Civic EX can only run high 16's in the 1/4 with a good driver. Some more people from HT should go in there and let them know whats up.
