well, 50 shot is very safe. just dont squeeze too many times in a day. and if your lx is 5spd, you will need a new clutch soon. im doing a 70 shot right now. i didnt wanna risk squeezing 80 shot anymore cuz i felt i was pushing it.

i have a lx coupe 5-speed too and i'm gonna get a NOS 50 shot soon. i think the dry NOS is what everyone says i safest. i'm too tired and lazy to look it up now. i'm gonna start searching for info on it soon. go with a 50 shot and read the nitrous post.

With a dry shot you take the risk of running lean. Why would it be safer in any way?

ummm, you cant run a dry system on the 7thgens because our fuel pressure regulator is in the gas tank. youll need a wet. or if you want safer.....go direct port.

its like that w/ most newer cars today. it doesnt make a difference about the trim on the civics, its all the same.we need a wet system. except venom from what i know.venom controls the fuel injectors. as for zex, i dont know how we can use those on our cars.

Umm and how exactly do you think direct port is safer? direct port kits are made to run 100shot and up, not to run a 50 shot in them....it would cost you a lot more money to try and run a 50 shot direct port that it would a single fogger. If you want a kit that will work on the civic get NX. Its a wet kit and they even have pics of one installed on an EX.

actually you can run less then a 100 shot on direct port misinformation strikes again!

well the nx is the same thing as any other wet kit.NOS has the same. they come w/ 2 solenoids(one fuel one nitrous).they have a 15 ft line for the bottle, they have the throttle switch....theyre the same. im using NOS theres no problems and theyre also safe.what makes ut unsafe is you can detonate w/ a wet kit and you cant on a dry. thats why the direct ports are good because it evenly distributes the nitrous in the chambers and lessens the chance of detonation.

not true. detonation occurs when there is a lack of fuel. whether you're running a dry or wet kit has no bases on if you will detonate.

save your mis-info posts I've done the research...and yes you can use less than 100 shot.....my question if I didn't make it clear is: why would you buy a direct port kit and run a 50 shot? the jets would have to be so small clogging would be a factor or, you would have to drop the fuel pressure in the area of 10 psi.
Or you could use motor cycle jets but that is a guessing game IMO. If you going to run no more than 75 shot purchase the single nozzle kit, for 100 or more get the direct port.

and if you didn't bother to fully read my post supernegro where did I say you couldn't run less than a 100 shot direct port? [IMG]i/expressions/moon.gif[/IMG]

here would be an example of the misinfo strikes again post.....yes your right on the even distribution of the direct port kit, but thats about it.....not sure where you thought up this other stuff.

clogging a factor? not really considering ive seen cars running a 60 shot direct port and as for dropping fuel pressure to 10psi? i dont know where you came up with that one geninus.

the reason you run a direct port kit is to get equal distribution of nitrous to the cylinders. N---TB--1-2-3-4 now if you can tell me the 1st and 4th cylinder are going to get equal amounts of N20 id like to see you prove it.

Dry kits are not the best thing to run and i wouldn't even consider running a dry set up with a small shot. maybe if you're just trying to spool up your turbo but even then i would run a direct port shot and have it shut off once the manifold reaches a certain psi.

that is straight from NX themselves. Reason is your running a very high fuel pressure causing a rich condition. If you bothered to check the AF ratio on a dyno with wideband 02 you could tune to make more power out of that 60 shot.
Clogging is a factor for those who buy oldler used kits and decide not to use nitrous filters and or get nitrous refills from a person who doesn't use nitrous filters on their refills, especially with tiny jets to run a 50 or 60 shot in direct port kits. The orfice is very very small.

that really depends on the flow characteristics of the intake manifold you use, not all cars use the same style manifold. But as far as a 50 shot wet, I haven't seen a problem yet other than user error.

IE too much ignition timing, not enough octane, improper porting of the manifold assuming its metal, not using the correct fuel and nitrous jet and so on.

The purpose of my posts what not to dis the direct port. I know what it does I own one. But to save the some people some money incase all they had planned was no more than a 75 shot

one is money.
two is their time for the shop to install
three shops love to jack that bill up when installing direct port.

I didn't have this problem since i got in on a groupbuy for my NX DP kit and I have installed several kits now and know what I'm doing.
