I would love to see an actual thread about the use of nitrous, one with out F&F quotes. That movie spread nothing but myths about nitrous.

There are a number of fail safes that can be installed. Window switch's control what RPM "window" the system will function. A wide open throttle switch will only allow the system to function at WOT. Then there are several more in depth fail safes that can look at things like bottle pressure to cut the system off.

Nitrous Express makes a good looking plate kit for the twins, it includes the WOT switch but I don't believe it has a window switch, something that is probably a good idea to ad.

If I had a local source for nitrous I would certainly try it out, its no more dangerous then boost. Use it correctly and intelligently it works great, get greedy and you'll have problems. Same goes for both spray and boost.

As far as the software tuning side of things I have no clue whats needed.

Heard of the WOT and window switch, but not the other fail safes like bottle pressure etc. I'll give it some more research, thanks.

Was also thinking that ECKTek tuning abilities are becoming more and more capable, there might be a programmable fuel cut feature that could be integrated if something suddenly goes wrong. A 50 shot probably wouldn't kill the motor instantaneously... but the compression is high, so who knows.

Same goes for boost, its not out of the question that one day a turbo car goes into boost only to find that the waste gate vacuum line has melted or fallen off. Oops and over boost.

There are as many fail safes as your willing to buy.

I always wondered if a tiny shot of nitrous on a turboed car just when you get on it, to reduce turbo lag, or help the turbo spool up quicker might be possible?

Thats very possible, mostly only done with large turbos. Spray the nitrous to get the turbo going, then taper off as boost comes on.

Wouldn't a twin scroll turbo just get rid of the lag all together without the need for nitrous?

Yes and no, I'm talking LARGE turbos. Certainly there are other ways to combat lag in the realm of common sized turbos.

The general rule of thumb is don't spray below 3k rpm so if your turbo hits boost at 3800 it wouldn't really be worth while. But if you have something large that takes more rpm's then nitrous could help fill in those lower rpm's.

Trevor Langfield wrote a very good book about nitrous. He is know as the Wizard of NOS over in the UK. He did the nitrous Jag on Top Gear. Its a very good read and discusses many of myths around nitrous use. There is a section on nitrous and turbos.

MotorBooks Workshop also has a Nitrous book, I've never read it but there other stuff is good. I feel like in the days of forums and internet, good old print books often get over looked. I used to read these kinda text books on my commute when I rode public transit. Now I keep them around my shop because they are full of helpful formulas and conversion charts. Most are a little out of date but they are still a great resource.

it would but the point is that nitrous isn't always there, you don't HAVE to use it.
Also from a little research it looks like N2O is cheaper to get set up than a proper twin scroll turbo.

I hardly passed chemistry back in high school but the play by play of how nitrous works is pretty cool, to me at least.

D sport actually did this already, they are running a 50 shot and are making good power about 220whp. I would check out their write up and that should answer most question...it did mine. I'm planning on going with the NX kit for the Fr-s

Nitrous is great and effective power adder. DI engines respond to it very well. Just make sure you use a wet shot.

Also use a step colder plugs and if you are tuned, speak with your tuner about retarding timing a bit. you do not want to run much advance on a nitrous setup.

thanks man, been laughing for a good while reading this. haha

I ordered the back issue

I came hear to troll but the good jokes have already been cracked.

Plumb the nitrous into the cabin. It will make the car feel like a time travelling Delorean.

I was just at my welding supply store today, I should have asked if then can get nitrous.

Justin bailey all the way.

I just got my copy of the D Sport magazine with the article about the NX plate kit. Definitely a good read. The NX looks great when installed I really like it.

Also as I have been digging around Ive found the Nitrous Express Octane series progressive controller, its pretty much takes care of all the needed fail safes in one package. Including a reversed ramp for boosted cars.

Found a pretty sweet nitrous setup over on Speed Hunters. Article says they started with a 50 shot through a custom plug in the intake. Then stepped up to the Direct Port setup as a second stage.

Yes great, we have all seen the movie. Can we try to keep this informative.

Does anybody know how does nos react with e85 and boost ?

I don't see why it wouldn't work. You would probably have to increase the fuel jet for the same reasons you need larger injectors.

This is a screen shot from the last page of the Nitrous Express plate kit,

The direct port kit is for sale, i found the owner. Pm me if you want to know more

Pm'd

Informative huh? Ok, sure...

Nitrous is a pretty awful mod for anything but dedicated drag strip racing... and I don't think there are too many people out there who bought their 86's as a drag-only car.

Why? Nitrous isn't something you can spray continously for extended periods of time.

Also, using nitrous on the street is absolutely retarded.

Now, if you are looking to take your 86 to the drag strip, and want to add cheap power, then Nitrous may be for you. However, I'm not sure what all there is to discuss? Aren't most companies kits fairly similar in design (aside from wet vs dry)? Or are you trying to gauge how large of a shot is safe to run on stock internals?

Awful mod ? Wow you're lucky this isn't a chevy or a fox body forum because you would've been eaten alive. I bet you haven't educated your self about a proper nitrous system which costs more than a few fi options for this platform

I bought mine to street and drag race, so this applies to me. Nitrous is also used in drifting championships if you are not aware, also it can be very helpful to spool turbos.

Why is it retarded on the street ? Maybe you are doing a highway pull.

No they are not similar in design you have a ton of ways to shoot, size and use nitrous

Nitrous/supercharger/turbo/NA is a choice everyone gets to make. This thread is to talk about nitrous. I personally find nitrous appealing, building a setup is something I see as a challenge. I enjoy solving the puzzle of assembling a functioning setup be it boost or anything really. Often I enjoy the build more then the final product. I know nitrous on the street isn't necessary but neither is anything faster then a corolla. I know I didn't go over 45 on my 20min commute today. And yes nitrous is used just when you want it, not continuous. But there is also a time limit on how long a motor will survive full boost pressure.

Its pretty obvious there is a lack of experience on this platform so no I am not expecting someone to chime in with a golden number and say it can handle this size shot. But its the same thing as when the turbo kits started coming out, how much boost will it take? no one knew but that didn't stop a dozen shops from trying.

Yes wet and dry are the two man types. All brands are not equal each one has there own way of making parts. Just like StopTech calipers are different then Brembo or some china brand. You can also look at some Euro brands that use a different configuration of jets to solenoids then the US brand use.

After wet/dry the next choice would be single nozzle, direct port, or plate kit. The NX kit for our cars is a plate kit with the mounting "plate" behind the throttle body. The FRS I posted above has both the single nozzle mounting in the intake tube, and the direct port kit with a nozzle "direct" in each intake runner.

A discussion thread about setup is always good. Take my M3 for example. One plenum to feed 6 cylinders each with a individual throttle body. A plate kit is out of the question with the ITB's. A single nozzle kit would only be good for a small shot as its hard to ensure each cylinder is consuming an equal amount of the charge. So for that motor a direct setup is best to ensure each cylinder gets the correct amount of charge. I actually bought a spare plenum to modify but that was back before I had a garage so the project kinda died.

Now the FA20 intake is pretty conventional so its pretty straight forward.

Did you fail to read the part after "awful" where I said "for anything but dedicated drag strip racing?"

...and don't most Chevy or Fox Body guys using nitrous on their cars exclusively for the drag strip?

I know plenty about nitrous oxide and how it works, thanks. I'm thinking that you may have played one too many Need for Speed games though. You don't just hit a button on your steering wheel everytime you want a boost and that's that.

Also, where in the world did you find information regarding nitrous being using in drift championships? Most of the championships I just looked into don't allow it, and for the few that do (like the UK), I haven't been able to find anything on drivers who actually use it... if you have some readily information on it though, feel free to post it up... I don't mind being proven wrong every once in a while.

But for the street? Idiotic. For starters, it's illegal in most states for street use. Secondly, due to the way nitrous comes on instantly, it can be extremely dangerous on imperfect roads. I mean sure, if you're running grippy tires and lack of traction is not a problem for you, or you're running a small shot of nitrous, you're probably safe. That still doesn't change the fact that you can't sit there and continually spray nitrous, though. If all you're doing is just a few pulls, okay, but it's not good for the engine to spray for extended periods of time, and there is only so much use you can get out of a bottle. If you want to run nitrous on a street car, that's your perogative, but it's still pretty stupid if you ask me.

I've had friends in the past spray nitrous on the street. Want to know how many of them ended up wrecking their cars because of it?

Not to attack you personally, but make sure you get some hella flush stanced extra camber, rocket bunny kit, and a big backwards wing before you try some street racing pulls with your naws.

EDIT: Just to clarify, I have to question why you purchased the FRS if all you are concerned with is straight line racing on the street.

there you go,(picture attached bellow )

Lol regarding me fitting a rocket bunny and camber, trust me I've driven a fair share of fast ass cars, on the street, on a track,on sand and water too :) . Im not saying im the greatest driver but hey, i manage to keep a 700whp single cab truck with nos in a straight line every now and then so don't i get some credit ?

Why did i buy this car if i only care about straight lines ? Hmm what other Japanese tuner looks nice and is rwd now oh and also has a stick ? Plus i have a car that would lap the frs around a track and also do it side ways. People think this car was made purposely to hug corners, but no its not; nevertheless its good at it, but also with its power to weight it can be a beast going straight

I've seen nitrous used on muscle cars on the street. I remember a guy who went as far as to disguise the bottle as a fire extinguisher.


Red button activation and instant on is old tech now. Simple devices like WOT switch's connected to the gas pedal have replaced that. Also there are numerous progressive controllers like the Octane Series I posted above. These allow the shot to happen progressively making traction much easier. You can even activate by RPM, boost, speed, rpm, or gear.

This thread has already touched on some of the fail safes in a good system. WOT switch, window switch, progressive controller.

And I think crashing a car because of nitrous is a misnomer , seems loss of traction could be a better description. Then again I don't know what happened.

I don't see any out standing traction hazards from using a shot on regular pavement. The D-Sport car made a bit over 200 ft lbs on a 50 shot. Plenty of boosted cars on here make more and they manage traction.

Just did a quick search to show that nitrous is used in professional level cars.

Thats just searching on one site.

I don't follow drift so I am left to searching for a "nitrous ban" I wasn't able to turn up any thing concrete, only rumors. Even if it is banned we need to know why. For example, F1 banned moveable aerodynamics for a while. Why, as a cost saving measure not because it was dangerous. I follow racing cars pretty closely and I learned that lots of time its whats banned that the good stuff. Look up the 1992 Williams FW14B, qualifying laps 2 seconds ahead of the field. The tech from that car is still banned today.

Interesting thread. I've run Nitrous on many vehicles over the years. I wouldn't hesitate to throw a kit on mine if I were so inclined. It is a blast!
