nitrous on nismo
 

I have a 2010 370z nismo and I want to install nitrous, what would be the safest shot and do I need one step colder spark plugs

75/100

That's without a tune or plugs, anything higher and you would need it. If you are installing nitrous and you are going to be seriously using it on a daily or weekend bases. I recommend a tune to retard timing/plugs/warmer...etc the whole nine.

$1300 roughly for everything

None.

Agreed.
Save the N2O for the Vtec boys.

both are wrong

Anytime you use nitrous, regardless if its a 10 shot or a 150 shot, you should be tuned for it. For stock block, i wouldnt go anymore then a 100 shot, but thats just me.
bare minimum required:

Dual fogger system (i suggest wet system)
tune
1 step colder plugs

recommend:
bottle heater
pressure gauge
afr gauge
tc window switch
purge

Not sure if its avalible for the Z's but we have a guy that designs a tuning program for the Evo's that allows us to flip between tunes with our cruise control buttons. It also automatically switches tunes as a safety measure if something goes wrong, ie if your bottle runs empty and your afr goes lean, it will switch to a non-nitrous map.

Did you just wanna say someone was wrong? Guess guys who have been using nitrous at the track for the last six years are doing it wrong? Thanks for the info will be spreading the word.

Also that program is called UpRev.

uprev can do this

as well as set up launch control (yes on 6mt) for those of u who might not have known that

Do lots of research..
 

I'm probably, one of the longest running tenured member here running nitrous without any issues. I was one of the first as there was probably only one other person who made a post about it back then. I did my research and went with it.


I hate posting up my experience because the majority here are "Anti-N20". My thoughts are if you have no "direct" experience with it. You should not comment about it. People read horror stories or tales about it Nitrous because most the time it was unproperly setup. But the fact is, anytime you go force induction you run that chance of something going wrong.

I've read many issues here about GTM this and that, blown motor, oil starvation. So should we stay away from TT or SC? No, just ensure that you minimize the risks by doing your homework, work with people who have been working/using N20 for years and tune with UpRev. Good luck on your decision.:tup:

My rule of thumb is:

If you are asking about nitrous on a public forum, you don't have enough experience with it, hence you shouldn't use it. That's why when people ask me if they should use it, I tell them NO.

It's not like a CAI or exhaust where you can't really mess things up too much. When things go wrong with nitrous, it can get REALLY expensive.

People like yourself that know what they are doing, don't need "our" help and will be fine. :tup:

I still don't get why folks are anti nos?

Force induction is force induction douches say otherwise!

I ran a 55 shot on mine for a while. Didnt change plugs or tune. It ran just fine. BTW its much cheaper to by an HR 350z kit, i bought mine from dyno tune.

Thanks, but as I recommended to the OP. Do lots of research, get all the safety measurements and use experts advise.

Exactly.... It's another form, and best bang for the buck when done "properly".

55 shot? Man that's tiny lol. :-)that's what big turbo guys use to spin their turbos... My first time with the 75 shot put a big smile on my face lol.. Now I run the 100 shot but I only use the bottle at the track.

If you want to see the first time I used nitrous on the Z search 671Messiah on YouTube ... Please excuse Simota1's comments. It was his first time ever experiencing nitrous lol..

:ugh2: wtf is the point of a forum then? What's wrong with hopping on a forum trying to learn something new...

NOS just has a bad reputation because it is cheaper then a more permanent boost more people who don't have the money up front use it (insert V-tech comment here). Being that it is low cost often people cheap out on it because they didn't have the money. And cheaping out on any upgrade leads to sever problems down the road.

The best thing anyone can do is buy or check out a book from those places know as libraries and read. It can be an old book too, the technology has been around along time.

These books have more knowledge then any one or 100 threads can ever give you. And will save you alot of time, pain, and money.

But if you just want a cheap not useful answer that doesn't take any effort please keep asking these questions. Here's mine, NOS is find you should do it, it is simple and effective.
:ugh2:

If you think a public forum is the appropriate place to learn how to properly install and use nitrous on your car reliably, then I can't help you.

Just installed a Nitrous kit last week... 50 shot... runs great! Just closed the gap on my stock plugs (Denso Iridiums) to .038.... Besides that no other changes. No problems at all. just dont shoot at the lower rpms, just to be safe.

I would like to see some more people go this route. if it turns out to be very reliable on the vq's, then it would be a good alternative to dropping $8k+ for fi

If you're going to run a Nitrous setup, than do it right. I would do a direct port to be safe, that way each cylinder is getting the same exact amount of N02. With a tune, you could run a 150 shot easily.

Without direct port, I wouldn't run anything over 75. Too much of a gamble.

I see your SC'ed but do you have "Direct experience" with nitrous? A direct port is the best way to go but don't believe its nesseccary or the "only" way to be safe.

With a tune you can do anything, thats a given. Just cause you run a direct port doesn't mean you won't run into issues. It just minimizes factors more.

As far as a 75 shot being too big, is this by first hand knowledge? Because using the stock map and spraying a 100 shot. My datalogs show that my AFR is running rich at a 10.xx according to Randy at UpRev.

I stated it was a gamble... and it is.
Anytime you run Nitrous through the intake you don't know how much each cylinder is getting since the stock intake manifold isn't meant to run a gas or liquid through it. I don't have personal experience, BUT other people have, including someone that blew their motor for me to learn from their mistakes.

You also didn't read the part that said, "I wouldn't run anything over..." That's my personal opinion, take it with a grain of salt.

Also, air fuel isn't the only factor in tuning. You can run rich as hell and still detonate.

I was the first person (at least on this forum) to hook nitrous on a 370z. Bought the car in 09, 2 months later i hooked nitrous up, 6 months later, sold the car...lol.

Really? I thought that you bought it for the car and never hooked it up before you sold it. I remember reading your post. Anyways, the only person I ever saw post a thread about nitrous before I got mine was a guy with a 40th Z.

How's the X treating you? I would have gotten an X if a dealership here carried them.

i had it fully hooked up and able to spray. Was just waiting for a tune, then i decided to sell the car. But i was defently the first to hook it up because it took alot of research and mainly going off the 350z's kit to see what i needed since i bought a single fogger universal kit.

The X? well, lets say she is having some work done due to this...

My tuner advanced the intake valve timing to much and didnt touch the exhaust side. To much air/back pressure, snapped the exhaust valve which jammed in the head sideways and chewed up the #1 piston.

Sold my FP Red turbo to buy a bigger FP Black turbo, but changed my mind. So did the guy that bought my turbo so im buying it back, as well as i just orderd a few parts, along with a new head that has been hot tanked and ported with +1mm valves, springs, cams. Hoping to have it back on the road by the summer.

As for now im driving a 03 cavalier and **** do i miss the Evo. Cavalier doesnt have power windows or locks, no cruise control. CD player doesnt work, not a 4 door. And its not AWD :(

Damn sorry to see the issues. Such a costly mistake. On a positive note, now you can make some serious power on a built motor.

nah, keeping it the same power i had, hence why im buying my turbo back. Was at 431hp, ill bring it to 450hp and thats it since its a DD.

Geez, sorry to hear. So did the shop take any responsiblity for the motor? Are they helping you any or is this a its your fault type deal?

Makes sense too

I was tuned by a guy down in the states that does e-tuning. Seemed like a good guy at first but few of his methods made me nervous so i questioned a few things. After that it was pretty smooth sailing. Once the engine popped i had no idea why it happend. I was at the drag strip that night for the first time on this setup. Wasnt hitting anywheres near the numbers i should have been. Stock i ran 13.5@100. DP, TP and air filter i ran 13.2@103. Evo's with boltons are mid 12's. So i should have been in the 11's for sure but i was only hitting 12.3@112 (hitting rev limit in 4th about 75-60ft before the finish. My last run my CEL came on. Checked everything out and it looked fine. None the less i told my buddies i was taking off to see what was wrong.

Half way home the engine died and wouldnt fire up. So i called a tow truck, asked for a flat bed and they sent a normal truck. Long story short about that, the tow truck driver didnt listen to me and cooked my tcase. They refuse to pay for the damage and i dont have the money or time to waste going to court over $1500.

So i thought the damage to the engine was from me. One of the other tuners on the evo forums asked to see my tune. Sent it to him and he confirmed that my tuner ****** up. At the same time there was a thread on the forum talking about my tuner. The tuner that looked over my tune, posted up what he found and i posted my thoughts on it. My tuner then emailed me asking me to call him. First of all, im in Canada and im not paying long distant fee's to call him when emails work just as good. Second of all, i was in the field with the army where cell reception was poor. I told him this and told him if he wants to discuss anything it can be over email. He denied blowing my engine up and i havent heard a word from him since.

Since then i was contacted by another Evo owner in Canada with the same exact issue. Motor blown, valve snapped and took the piston out. He sent his tune to the other tuner that looked at mine and our maps were nearly the same.

So the tuner refused to help with the engine and the tow company refused to pay for the damage they caused to my tcase. So its going to be about $5000-6000 in parts for my engine, $1000-1500 labour to rebuild the engine and $1500 to rebuild the tcase.
