Sup fellas,

Well, its time to get the Z caught up to speed. The bike is hitting low 10s with just a few bolt ons and some shedded weight. The Z, is sadly far behind. Just ordered my NX EFI kit, "T" adapter, TPS, window switch, purge valve, and gauges. I have no idea when I'll have time to install it all. I haven't had a day off in 2 weeks. Working in Austin on the weekend to suppliment my automotive habits. Anyone having problems with the stock ECU pulling timing with just a 100 shot? Gonna have to tackle this sh*t in a couple weeks. I have a Bike event east of San Antonio that will last all weekend (August 12-13) and will be working this weekend in Austin. Hopefully get it dyno'd the day I install it all. Looking for at least 400lbs of torque, but we'll see. *fingers crossed*

 

wow nice. me = jealous. be sure to keep us up to date on the install. what are your plans for tank location, purge location etc etc?

 

Referring to your sig:

Or buy it and trade it for a newer hotter one every 2 years

 

thats the nice thing about NX. no need to pull timing. even at a 150 shot, but you might want to thing about doing it with anything higher then 150.

 

Gonna put the bottle between the strut bar and my head. lol. Have my old cut up gym bag from the civic about 5 years ago. That's my way of hiding the bottle. I see a few guys on here have done the same thing. I must have mentioned it on here too many times, now the secrets out. lol. Purge...hmmmm. I usually put it sprayin up the center of the windshield, but I'm trying to hide everything this time. I might make it purge out the front bumper. Its still kinda up in the air. Suggestions welcome.

Hahahaha. Yup, that works too. Although I don't usually keep cars that long, or women. haha.


Yea, I see alot of you guys sprayin 150 shot. I just prefer to have a UTEC or some kind of management to tune for such a big shot. A progressive controller would be even better cuz 150 horse straight up would make me spin my factory 18s like crazy. Who knows though....I might up it if the car still feels slow as she does now. My perception of fast has been skewed since owning several bikes. Kinda spoiled the car thing, but we'll see how it goes.

 

Going in next week. Just ordered dynotunednitrous TPS/Window switch so I can control when it sprays....The gear selection thing is badass. We'll see how it works when it goes in. No spraying in 1st makes for better runs.

 

Please explain. I'm new to Nitrous and am trying to absorb as much as I can.
I'm assuming it's because because 1st would be a waste of a shot since you won't get that far in 1st anyway.

 

and youd prolly spin through first...

 

If you have the switch on the shifter close to your hand, the only time you'd want to spray in first is right after your tires catch from launch. Aftermarket wheels and tires would be ideal, but if you're running stocks, its not even worth spraying in first. You'll just spin em. A time delay would work in this situation. So yes, traction is the issue. I have stock 18s, so I won't be spraying in first. I get better times just launching with the motor alone.

When I had nitrous on my civic, I could get away with it, but I actually preferred not to. Since the Z can take such a big shot stock...I'm sure you know the rest.

 

sounds logical...I'm running 275/30's in the rear.. Last night I was discussing different nitrous options with my team mates. Needless to say, I'm far less knowledgable than they are. I did learn the difference between dry & wet shots though. Wet shot seems to be the better of the two, but also less forgiving if not tuned properly. Luckily SGP is right around the corner from me. I believe I might let those guys handle the install, although I'd be willing to tackle the install if I became more savvy with the world of nitrous.

 

I would pull timing with anything over 100shot personally. In other words if you dont have a tuneable EMS stay at 100 shot. If you can get a hold of race gas, you can run 125 shot safely and slightly leaner A/F's...

 

Please explain "pull timing".....EMS I'm assuming, is a piggy back management system for the tuner to utilize when tuning your vehicle.....

 

Pull timing = retard timing. Its recommended with N20 and with FI, although you dont need to pull as much on the spray as you do with say a turbo (less heat)

 

I need to learn bout nitrous as well.. i'm the noobest of all.. subscribing

vo, you wanna explain the dry and wet shots? also isn't there another type of injection?

alberto, what would the retarded timing do? why would you want/need to do that?

 

A dry shot is where nitrous is injected into the intake. It cools the air coming into the engine. A dry shot taps into the fuel lines. The nitrous is injected into the combustion chamber along with fuel. Air, fuel, and nitrous are all mixed at once. From what I've been told, a wet shot is more efficient but needs greater care when tuning. There's less room for error out of the 2 different shots.

 

PM me Chris. I found an excellent write-up on Nitrous. I can't post the link here on the forum though. It will violate the TOU.

 

* The second sentence he meant Wet shot... The wet shot is mixed with fuel instead of being completely nitrous (dry shot).

But vo is right, there are some good write-ups out there that you can read that would make alot more sence then me trying to get my thoughts down in typing. lol.

 

nice man!! good luck with the install, please pm me if you have any questions, i have done it all with nitrous and our cars....

 

Appreciate the offer Audible! Been spraying for the better part of 12 years. I might need some advise on the DynoTune Nitrous TPS/Window switch though. Never used this product. Not sure if you have. I tried to PM someone I saw that's using it, but no reply yet. How's the shop doing so far? I need someother bolts ons (i.e. plenum spacer, headers). I'll have to drop in and check it out! Pictures of install will be up later this week guys. Should be able to finish this thing monday. I have the entire week off this week!!

 

OldSchool - I'm just wrapping up my install (should post pics in the next few days)...I'm using the tps/window switch from dynotune - it took me a 2nd try to get the tps working right, but it's all working perfectly now...let me know what Q's you have.
