Sorry for getting back so late, I am still in Afghanistan. Okay so Yes Direct Port is the best way to go but those are usually used for bigger applications around 250 plus which obviously I am not doing. I should have stated running a wet kit is preferred b/c as you know dry kit you only spray nitrous, wet kit you spray nitrous with fuel. I am no where saying I am a nitrous guru and I get your playing devils advocate. What is the biggest shot you have done with dry? In my experience I generally don't hear a lot of people going big with dry kits. It is to my understanding that when you run a dry shot you are betting on the fuel system to compensate on it's own? That means your putting all your trust in the vehicle figuring out what to do once nitrous is added vs the fuel already going in with the nitrous at the same time.Your application is going to dictate which kit to use. I believe that wet kits are safer, and they are also highly recommended and if you ever want to go FI you can keep your wet kit and apply it to your setup. In the end no matter which way you go TUNING will always be the deciding factor.

So just an update, I bought a motor from Z1 b/c well it was easier then going through to see what was messed up in the old motor. I bought a new bottle bracket with a built in heater that will come with a kit to dictate how long the heater stays on depending on the bottle pressure. I will still be going with 150 just gotta find the right guys to tune it once everything is set up. Bought a few other misc. things like a bunch of red silicone hoses, back up light, stealth blinker lights, twm short throw shifter and I am sure I am forgetting a few things. Should have the vehicle running in about 3 weeks. Then back to tuning. Those of you still running nitrous I'm jealous! Has anyone gone beyond 100? Numbers on a dyno?

I think my uncle use to run 150 shots dry on his Z31 N/A(id have to ask him again to be sure) and i did run 100 shots dry on my eclipse before having to remove the kit and sell it(ref ticket) but with the n2o tune i had, it would retard timing and make the car run extremely rich(had 600cc injectors) so when i was spraying, the AFRs were just right

I havent really looked into N2O since then but to do anything with dry kits, you have a **** ton of tuning to do but once its set, it should be just as reliable as direct port(theoretically at least) because each cylinder is either getting enough or more fuel than it really needs, the only reason i say that is because if you went with a wet kit(not dp), there might be a chance where the intake manifold isnt flowing enough fuel into one or 2 cylinders, so those will run lean while the others will run either run just right or rich

dont get me wrong, after i supercharge my Z im going to put a wet kit on but i'm not going to run alot(maybe 50 shots) just because it will require less tuning but dry kits can be reliable if its done right and tuning is spot on


anyhow ill stop derailing your thread XD
good luck with your build, im really interested to see how it turns out

I ran nos on my mustang anything below 50shot it fine dry
75 - 150 wet kit just make sure your getting a good spray pattern with the kit
I was getting lean conditions on the rear pistons and rich conditions on the front pistons because the spray pattern was not that good
Direct port is the best way to go as to not get lean or to rich
I never sprayed below 3k and stopped spraying 500 rpms before redline in case of a miss shift
And because 150shot is like 200-225 additional torque i used a kit to bring the nos on 25% then ramp up to 100%

Just got to stay on top of the spark plugs and your good

Seriously thinking about pulling the trigger on a kit. I know nothing about nos. Reading this thread has been helpful, but i feel like i am still missing a few things. Would someone like to PM me about it. Thanks

I think it would be beneficial for anyone who is looking to do N2O to have the info available in one thread(don't know if this would be the right one, mods please advise)

Since its your first N2O install I'd recommend running 30 wet shots, getting one step colder plugs, and retune(not a huge deal if you don't because when you spray a wet shot, you add fuel with the N2O and you won't be running a lot of N2O)

If you want more info on this I suggest you go to LS1Tech's nos forum, they have a lot of info there.

What are we talking about? A honda civic? LOL Buying the jets for a 30 shot, getting a tune and paying for colder plugs would be such a waste of money, you would be better off just buying race gas. He will be okay with 75 wet shot no tune, and even on stock plugs.

LOL retune on a 30 wet shot? Are you serious? For 1 you won't even feel a 30 shot and two you can run a 75 shot all day on stock mapping no tune and just be fine.

Do I have any experience you may ask. Well I'm one of the longest tenured member here who's been running nitrous since the car came out. I've had tons of passes at the track and ran through more than 50 bottle refills with no issues except a bad emu. Other than that I've had no problems.


And for the record it's Nitrous not "NOS". NOS is a company brand, just like Zex, NX, Venom Etc. Please don't confuse the two. Everytime I hear someone call it that it reminds me of FnF:ugh2:

I have never ran anything less than 100shots before so i am not too familiar with anything lower and im not running n2o on my Z

I only recommended a retune and colder plugs because thats what i had to do running 150shots on my eclipse, plus I dont want to be that guy who says you can run XXshots and be fine with no experience with n2o on the 370z

the way i look at it is, its better to have everything and not need it, than it is to need it and not have it

and i usually call it n2o seeing as thats easier to type out than nitrous oxide but if you are to say nos to anyone, they will know what you are talking about, its like kleenex is a brand for facial tissues, yet everyone calls facial tissues kleenex(same with band aid)

So if i have full bolt ons and a custom tune, should i get retuned to be safe? Colder plugs? Even with only a 75 shot? Im sitting at 322 whp on a mustang dyno

100 + shot is where things become a little more serious but even at 100, colder plugs aren't really needed. Its recommended on most applications to have the timing retarded 4 degrees per 100 so that would be a concern as your car is tuned and unaware how far your tuner advanced timin to make better power NA but even still questionable. 75 shot with an a/f guage and cut off switch you should be fine. Just be sure you get all the things that make it safer to run and keep your bottle pressure consistent when spraying. Running out of spray in the middle of a pull can wreak havoc if you don't have the a/f cut off switch.

Iv never even heard of someone running a 30 shot(s) before. Why do some of you guys say shots? That right there tells me you don't know what your talking about. A 370z will not blow up with a 75, 100, 125, or 150 shot. If I can put a 150 shot on my 350z with a stock block and no tune for over a year and a half, then a 370z will be able to do the exact same thing.
Luigi I would just stop talking if I were you. Why are you trying to give advice if you have no experience with the subject? Stop giving crappy false information. The minimum anyone should ever put on a Z is a 50 shot to make it worthwhile. Even that is almost nothing for the car. Some people on here are seriously retarded

Are you talking about a dry kit?

I ran 150 wet in a 4V 4.8L no tune just a cam, headers, exhaust, and the nitrous kit. Car ran well put some good numbers up at the track. Over time I blew the valve cover seals. So I ripped everything apart. Pistons were screwed amongst other things. I guess what I'm trying to say is if you want to run nitrous build the motor for it. And it can be a beast! But I honestly think it a poor man's mod. That youngsters go to first because they can not afford to build the motor or go FI. Again this is just my opinion.

So your pistons were screwed and you fried the piston rings? Did ripped apart everything with the mad scientist?!? LOL sounds too much of FnF 1.

Poor man's mod!?!? So I'm guessing that cars that are built for nitrous, the owners are poor?

Nitrous is a form of force induction, just like turbo and sc. All forms of force induction can be made to be safe if done right and properly. You can run a TT kit all day @7 psi at the waste gate and as long as your tune is good you'll be safe. Same as running a 75 shot etc. There are tons of cars out there that have insane ETs and WHP using nitrous as their main power adder or sub power adder.

It's people who have no business chiming in on nitrous or other forms of information help who have no clue what their talking about that bugs me.

I think I've read about you getting every single TT kit or BP kit around here:rolleyes: For someone to say nitrous is cheaping out on going FI that's the same like someone buying a beluga exhaust because its cheaper than going Fast Intentions or other more recognizable brands.:shakes head:

i know someone who runs 30shot(is it shot or shots? i have always heard it referred to as shots when talking about n2o but i could have misheard it) wet on his G35 along with his supercharger, he gained about 60whp from it and he even runs 2 maps, one for when he is on spray and one when he isnt, and i do have experience running n2o, just not on the Z platform so i dont know how much a bone stock motor with a stock tune can handle, if it can handle 100shot wet on stock everything than great, run that, i still wouldnt recommend someone do that(and i never will, i personally dont think running that much n2o is safe without retuning and getting colder plugs)

im not claiming to be a n2o guru here, but i have my opinions on running it and i dont think my opinions will change(well not easily at least)

i couldnt agree anymore, in fact i would argue that n2o is probably safer in the long run(if its tuned properly of course) than a turbo or supercharger is because you are not spraying 100% of the time unlike a turbo/supercharger where you will always be in boost no matter what so it isnt wearing out your motor as fast


@everyone
im sorry if im spreading misinformation or giving bad advice, i am not too familiar with n2o running on any VQ motor but i am also in the process of learning because i eventually want to get a good n2o setup going on my Z
