I have a b16 with ctr cams and pistons. I was thinking of adding a nitrous kit to my set up and maybe going between a 50 and 75 shot. Is this stupid. I heard if you keep it under control you won't have tons of problems like most say. Is that true? And also the difference between all the kits? Whats good and bad, pros and cons. I heard the way to go is with the n/x kit where it dumps straight into the fuel rail? And what upgrades do I need to go with to make everything else reliable. I think it will give me the extra boost I need but I want it to be reliable and no one around where I live knows about how to do it right, they just know how to buy something off ebay and hook it up haha. But thanks and hope to hear from the best.

 

To make it reliable retard timing 2-3 degrees per 50 shot..
Run colder spark plugs and use 91+ octane to keep from detonating..

In my opinion you shouln't use more then 100shot on your set-up..
using Nitrous is a gamble everytime no matter what motor you have so..

 

you shouldn't have to retard the timing at all if you go with the 50 shot. At 75 i would take it down one, or maybe two degrees. With a 50 shot, as long as you don't use it constantly (which would mean you would be beating on your car alot anyways), it should be just fine.

Just be sure you have a warm enough bottle and enough snot behind it. (pressure)

edit: Get some NGK BKR7E's also.

Nitrous is absolutely no more of a "gamble" than any other power adder. I would run 50 shot with 2-3 degrees of retard.

i should have read your post thouroghly the first time. I didn't comprehend that you had CTR pistons in. With the nicely bumped compression, you have to take into account that the shot is going to be more than advertised. I would definately use the best gas i could grab and retarded timing a bit.

Remember, n2o is fun!

 

Is there a better kit to use than another. Wet or dry? Whats the major difference and is there a difference in the brand? I think I might take your advice and use a 50 shot first and then maybe go up from there. My setup is pretty nice now but I think nitrous will give me the boost through 2nd and 3rd that I need to take off.

 

i read in someones sig

"nitrous is like a hott chick with stds...you wanna hit it but your afriad of the consequences"

 

Nitrous is like any other type of forced induction...it allows the car to burn more oxygen...but in order to take advantage of this extra oxygen burning capabilities, you need more fuel. There are two different types of kits that utilize 2 different ways of adding fuel.

Dry In this setup nitrous only is sprayed into the motor. Upon spraying, components of the kit cause a large increase in fuel pressure. This results in the increase of fuel you need.

Wet In this setup, there is no "fuel pressure rising". Instead, your fuel system is tapped for fuel, and in the same way that nitrous is injected through the nozzle, so is the fuel. The nozzle is a "Y" configuration with nitrous and fuel entering together. A seperate jet is required for each "portion of the 'Y'", and this allows you to richen or lean your nitrous mixture.

It has always been an opinion of mine that anything that utilizes rising rates of fuel pressure is 'probably' not the best way to go. I would go wet if I were you. NOS, and NX have always been my favorites.

Also, look into the MSD digital 6 ignition controller. This controller will allow you to retard timing only when you spray nitrous.

 

damn you guys sound like you really know your ****!

 

mmmmmmmmm. I love nitrous. I would put it on my lawn mower if I had the paitience to figure it out. Retarding timing 2 degress per 50 is not a bad idea. Just dont do a 275 shot. Bad things happen to little motors. NOS is the best known and is what I use. Also go wet. The best system for reasonable price is direct port. Also an adjustable fuel pressure regulator is a good idea and high flow fuel rail and pump too. High octane is safest. Around here you can get 100 pump gas at citgo.

Direct Port is definitely nice, but I wouldn't bother on anything smaller than a 50-75 shot. Unever nitrous distribution doesn't become a "big" problem 'til over that range....and DP is quite a bit more work.

Go wet, single fogger unless you've got money coming out of your ***...if you do, take a picture, I bet it'd be funny. Then, go buy direct port.

Also, I would scan the classifieds here, a nice wet single fogger kit can be had for $300 pretty easy.

 

With most direct port kits they do not recommend less than a 75 shot NOS wont even give out the pill combos-I have 2 cars on the bottle and have had n20 for over 3 years now- 50-75 on 4 cyl75-100 v6 is all I would recommend-I never had any problems untill my ignition messed up on the crx-coil wire came loose and melted 3rd piston,but that was a good excuse to go dual cam on the bottle-I love nitrous

 

i hope that you are not putting nitrous on with stock fuel pump what do you have for fuel upgrades

 

I don't have major fuel upgrades on now. But I have a gsr fuel pump and a vafc 1 that I have to put on. I am not wanting to go to big with the nitrous. I thought I would go with a 50 shot first and maybe gradually step up to the 75 but no more. I have been in other peoples cars with nitrous and it is instant power to the wheels and I think that a 50 shot and vtec should be enough for that extra boost I need.

 

That is what I said when I first installed nitrous 7 years ago on my civic. It started with 40 then 50...........65............75...........85........ .....100..........125...........then it would not run right. You will know if it is too much. When you hit the button and it tries to bog you are not runnig the correct mixture and not getting enough fuel. Stock civic rods will handle a 50 shot (correctly installed) all day long. If you go dry, do not forget the fuel pressure cut off switch that everyone forgets about. IT will save you in the long run. It causes the nitrous solenoids to deactivate if fuel pressure drops dramatically. So it does not damage your engine. If you go wet, it would not be a bad idea to install a top rated air fuel ratio guage to see what it does when you are juicing. That can help you adjust your jetting. They are not perfectly accurate all the time but it helps.

 

you might also consider a ZEX kit (get the wet kit) seeing how your new to nitrous, it's extremely easy to install...so a lot of the rookie install mistakes can be avoided. I personally use a NOS kit...but have installed lots of ZEX kits and they are by far the easiest.

 

A far as installation whats the difference between a zex kit and nos or n/x. You say a lot of mistakes can be avoided, what are some of the mistakes? My buddy has a zex kit and a jacobs ignition for 350 that he said he had on his car and sprayed like 3-4 times and took it off. Is this a good deal and waht do I have to watch out for. And I am interested in the full throttle kit. Is their a major difference in those?

with the zex kit the solinoids are already setup in the zex box...wiring is like 3 or 4 wires...and the zex kit uses a WOT switch that works off the TPS.

350 sound like a good deal to me..."what to watch out for?"...make sure the right size jets are in there...that the system only sprays at WOT...the system does not spray when the car is not running ie... someone floors it when the cars not running etc... make sure you get fuel from the presure side not the return line...etc...

also the zex kit instruction come with a pretty good set of do's and don'ts

good luck
