My buddy has a system he wants to sell me. It's a NOS EFI system, wet 75 shot. He bought it for his ford escort... I have no idea if it would fit on my car... It's a single fogger system.

I can get it for 600$.. but I would even pull the price down more. I wouldnt pay that much if its not direct port.


I also not too familiar with No2.  :-\

Single fogger vs. direct port... whats the advantages.. and different circumstances they would be used in?

this is just kind of a guess but here's a quick lesson:

the reason for port injection is that it prevents the fuel from falling out of suspension. turbulence in the intake causes fuel to fall out of suspension, but air reacts better if it is turbulent, so if the air is turbulent the fuel will fall out, so with port injection it doesnt have time to fall out of suspension.

with nos, it is naturally a gas, so the theory would stand that it would work better if it were turbulent so the single fogger, with the same amount of nos being pushed out, will 1. burn cleaner 2. be a much simpler system. and assuming where you are the engine is a port injection system so the intake is designed to be turbulent.

make sense? if not let me know and ill take another crack at it.
i see no benifit to a direct port nos system. so the single fogger should be benificial.

i'd still try to talk the price down a bit ;)

The the thing I heard with single fogger injection is that it builds up in the first couple cylinders. I'm guessing besause of the fuel falling out of suspension. but I'm not sure.


ok edit: guess that doesnt make too much sense since the injectors are designated to each of their cylinders.. I guess i meant nitrous oxide build-up in the first couple cylinders.

ya that the problem with throttle body injection for fuel, but i don't think it should affect nitrous. the same way that your intake is designed to keep the air in each cylinder even if you inject the nos at the throttle body it SHOULD do the same with the nos. nos likes being a gas, so it acts like air does. follow? i know im not being crystal clear, im aweful at teaching online., not that great in person either but im better.

Yeah I get what your saying...  I'm sure BV will be here making it super clear sooner or later..  ::)

I'm still puzzled on how the flows of fogger and direct port differ and what would be more benefcial on our engines.

i can't help you as far as which will be more benefical for our engines, but the single fogger should do ok, considering its a whole lot easier to put in, and doesnt require drilling into your mainifold(ussually its a plate that goes behind the throttle body) as opposed to the direct port where you have to drill one hole per cylinder ussally.

I'd never recomend a single fogger system for a newbie ESPECIALLY on a V6... The Plenum design tends to have pooling/puddling troubles in the first cylinders and can cause EXPLOSIVE detonation (read this as engine DESTRUCTION)

The only ones that have worked are the Venom VCN-1000 and VCN2000 systems as they have Air Fuel monitoring and auto shutdown ... I've been running the 2000 system with mods...
Direct port is a far safer system as it provides Fuel and nos into EACH intake runner ...

is the 1000 dry?

Im looking at the 2000 kits and they are way too pricey for me. And also looking around for other companies kits.. I hate how complicated it is to find sh!t for our cars. >:(

is there any cheaper kits from NX, ZEX, or NOS?

how much did yours run you BV?

1000/2000 are both dry systems but like stated before they have MONITORING ... There is no guarentee even with the monitoring ...  You will have to add a bigger fuel pump to ensure fuel to the injectors ,Swith to copper plugs (no Plats or Iridiums) I got my 2000 at a deal as the shop ordered it ,and never sold it ... They will require set up as they look for 5 volts WOT and our cars never reach that I've had trouble with it 13+ brains have died on me ... The newer ones will be programable thru the palm pilot they use...
NX have crap solenoids they stick OPEN ...
Zex= Junk they use a diaphragm system to enrich fuel , also prone to failure and don't even list an application for our cars as the type of fuel system we use
NOS= OK in direct port but the dry systems will puddle/pool badly

ok dry systems will puddle...?  but the one I can buy off a friend is a single fogger wet system. So does that change the whole perspective of the puddling issue?

or.. single fogger puddle whether it's wet or dry?

Correct wet/dry can puddle in fogger
Direct port is the BEST SAFEST bet

Dry nitrous systems do NOT puddle in the intake.  There is nothing to puddle.

The VCN-1000 increases injector pulse when the nitrous is on.

I can get you a new VCN-1000 system from $700+shipping.

I want to stick with a wet system... I'm not looking into upgrading my injectors or anything.. and I dont like how to computer has to act with a dry system.. instead of it all working through the wet system together. And the safety/window switches.. etc.. that the wet systems offer seem to be alot more safe


Correct me if I'm wrong .. idk if the dry system offers all that safety..

in order to run a wet system on these cars, you would have to run a direct injection setup (each cylinder has it's own nozzle)

if you would like I can give you a price on a direct injection setup.

I would also be using an MSD ignition system.

If you do not plan on turboing or supercharging your car, I would go with the 6-Digital Plus box.

Has a 2 stage built in rev control and you can retard the timing with it, which you need to do using nitrous.

what would the estimated price of all that run me?

NX Express 6 cylinder direct port nitrous system - $810

MSD Digital Ignition Box - $319.50
MSD Blaster 3 Coil - $39.30
MSD Coil Mount - 5.10
MSD Vibration Mounts - $15
Modified Distributor Cap - $65.99
Distributor Rotor - $16.95

Total - $1271.84+shipping

You will need a shop to add extra material to the plenum to be able to drill and tap for the nozzles.

I would also install a wideband 02 setup to know if you are rich or lean.

You will need to tap into the fuel system to feed fuel to the solenoid for the nitrous kit.

wow .. ok.. So I'm gunna guess 2000$ after gauges, sensors, accesories, etc..  and all the above ^..

You were not around during the early days of NOS here ....YES there definately IS a pooling problem with the dry systems the gas flowed way too heavy into the first runner and caused MAJOR MAJOR piston/engine damage .... There was at least 6 members that toasted engines

About $375 and up for a wideband setup from autometer.



How can a gas puddle?

It floods the entire runner full of NOS and then when the valve opens it floods the piston with RAW NOS and the resulting flood causes MASSIVELY lean condition... You can guess the rest

so its not really "puddling" more of collecting its just called puddling. right?

I don't know the term...Just the results ...

sounds like turning on the NITROUS to soon (at to low of an RPM) which is a no no...

Aren't window switchs installed and programed to prevent that?

most systems use WOT switches...it is extra for RPM switches.

Dry system with NO FUEL enrichment .... WOT switch ... But hey what do I know ...

well the term is "puddling" but it got its name(im guessing) from what gasoline does in older V engines(before fuel injection). i was just saying that the term SHOULD be collecting. just an observasion to prevent the confusion that a gas magically turns to a liquid. though we all know how magic works on cars, like those stickers that add horsepower. and the taller the spoiler the more magic it has in providing more downforce it has, even if its only held down with wood-screws.

I don't mean to steal the thread but i have a zex dry kit just lying around, will this work on my car? Its a 2000 with the 2.5 v6.

Guess it's to hard to READ the thread

Well you don't have to be an ass about it, the system he mentioned is a wet kit. And I know its not a good ideal to use a dry kit on a returnless fuel system only continuous systems. So I figured I'd ask.
