problems with / opinions on ZEX

you meant to tap into the vacuum hose but tapped into a fuel line instead???? Is this a wet or dry kit?

Its a dry kit

Its a dry kit

Well he also has a 95 eclipse gs and his Fuel Pressure REgulator is in the engine. Mine is under the passenger side of the car towards the back. Im pretty sure he put it in the wrong spot. =o

 

[1fast97gsx]

well if it's a dry kit a fuel line should never be tapped into so he definitly tapped in the wrong spot and I would fix the fuel leak before I even consider driving the car again. Not to mention fuel going into the zex box where air pressure is supposed to go is not a good idea. As far as the correct place to tap ... yea on a 95 there is a fuel pressure regulator with a vaccum line under the hood which you tap into. On the 96+ I'm not sure how the fuel pressure regulator works, but I always heard those didn't even have this vaccum line and a dry kit won't work on 96+. Either way that was definitly the wrong place to tap and it needs to be reversed before the car is driven / started again.

So there is no way a dry kit will work unless I get the nitrous shooting into the manifold then Oh this isn't fun. Is there any way that i can use the kit that I have at all? Or do I just need to sell it....

huh!?

Is there any way to modify the Dry Kit to use in my eclipse? Since I dont seem to have the correct vaccum hose, or do I just have to get a whole new kit? I dont know anything about nitrous so I know my questions are like

first find out if you have a vaccum hose that runs to your fuel pressure regulator. If you do not then you need a wet kit or a direct port kit. You can convert it to wet with complete conversion kits they sell on ebay. First find out if there is a vaccum line for your fuel pressure regulator on your car. I'm not too familiar with n/ts at all .. the only reason I know it will work on a 95 is because my daily driver is a 95 talon but rumor has it 96+ are setup different.

Thank you very much for your help I really appreciate it

if im not mistakes the 95 plus cars dont have a vacume line commin off the FRP theres realy no safe way to hook up a dry kit if you cant boost off the fpr, nitrous is not a toy, its a great power adder, but not to be abused, it can kill you, and or damage your motor.

the 95 turbo cars have a vacum line coming off the apr the nt ones might not.

the zex kit doesnt tap into the vacuum line to BUMP up the fuel to make up for it....its there for saftey...if it reads low vacuum or any problems with your fuel setup it shuts down so you dont screw anything up. thats why they call there kit the saftest...other kits dont read anything its ether on or off regardless of fuel problems

That is absolutly not true, sorry.

The vaccum line IS ABSOLUTLY there because the system depending on the bottle pressure applies pressure (using nitrous) to the top of the fuel pressure regulator to bump up fuel pressure to maintain the proper air fuel ratio. It add a certian amount of pressure varying with bottle pressure to keep you in what ZEX calls the safe a/f range, this is why their system is safe. All DRY nitrous kits do this, not just zex they just market it.

THe vaccum line is not there to check anything. Nitrous injected into the car needs fuel, no if ands or buts. If the fuel pressure is not bumped up at the fpr then the car would blow up. The car does not change pulse width or duty cycle on it's own when nitrous is sprayed in. You can either bump up fuel pressure (dry kits) or spray the fuel in (wet kit). The only alternatice is a Venom kit which hooks to the injectors and increases pulse width with a magic box to compensate for nitrous, but it's still a dry kit.

This is the basic basis of how a dry kit work.

This is the inside of a ZEX NMU. You can clearly see that the vaccum line shares the distribution block with the nitrous, the nitrous running to the top of the FPR is what keeps it closed thus raising fuel pressure.

Also see below a my old NOS4123 dry kit with the vaccum line hooked off the blue thing inbetween the solenoids which are hanging upside down.

Look, i'm not trying to be an ass or anything, but there is a lot of mis-conception about how a nitrous system works and I police this forum to help dispell a lot of it. I hope you don't think im trying to personally attack you because this is not the case...

Hope that helps.

i think its a good thing you got to this before anyone else

I also run the Zex wet kit. I have been running a 75 shot for some time now along with my FP ported Big28, HKS 264/272 cams, GReddy fmic, etc. I run about 19psi, and when I spray my boost jumps to 22psi. The car runs extremely strong. I love it!! I have pulled away from stock ZO6's quite easily with my set up.
