The Nitrous Guide !

[FordFasteRR]

I would like to use this thread to highlight the main concepts behind installing and using Nitrous. As information is added, I will update this first post respectively.

Section A
Requirements: <<< Read First <<<

#1. Be sure to use Premium Gasoline at all times.
#2. Use at least 1 stage colder than stock spark plugs. (NGK: BKR6E-11)
#3. Mount the fogger nozzle 3 to 6 inches before the throttle body and aim the fogger directly into the TB opening.
#4. Use teflon paste instead of teflon tape to prevent bits of tape from clogging the filters and solenoids.
#5. Always mount the nitrous bottle in the trunk using screws or bolts that tie directly to the metal floor pan (this will keep the bottle from flying around in the trunk and possibly rupturing).
#6. If you want to spray more than 100 HP be sure to retard the timing by 1 or 2 degrees. (and possibly... be ready to buy a new motor in a few months)
#7. Avoid using "Dry" nitrous kits, they depend too much on the stock injectors and they are usually not good enough for the proper fuel flow under nitrous use. Use a " Wet Kit " instead. (not to mention that you cant even hook up a traditional dry kit to an XD because it has a returnless fuel system and there is no Fuel pressure regulator on the rail to tap into "which is how traditional dry kits work").

Suggestions:
#1. Avoid wiring your nitrous system using a manual switch, hook it up to the throttle switch to prevent spraying at the wrong time.
#2. Use a bottle warmer to heat up the bottle for more consistent results from the nitrous system.


Suggested Jetting to use:

Nitrous Oxide Systems
34N/18F 40HP
37N/22F 50HP
39N/24F 60HP
41N/26F 70HP
43N/28F 80HP
46N/30F 100HP
52N/33F 125HP
61N/38F 150HP

IMPORTANT NOTE: The XD uses a returnless fuel system with slightly higher fuel pressure than standard return based systems. As a result, you will need to jet the FUEL down by at least 1 - 3 sizes. For example: when i was using the wet kit on my XD, i had the 43N jet and a 25F jet instead of the suggested 28F jet... When I first tried it with the 28F jet, it ran poorly and didnt seem to have such a "KICK"... As soon as I switched to the 25F jet, The car would SCREAM when the nitrous kicked in !...


Section B:
Installation Guide:

This section is meant to detail any specific tips/tricks to getting the nitrous system installed on the Elantra XD.

The trickiest part of this install is most likely the fuel system part. Normally, for any wet kit, you have to tap into the fuel system to supply fuel to the fuel solenoid. Here are some tips for getting the fuel there.

ok, there are 2 ways to tap the fuel line...

the first place is just before the fuel rail, on the part of the fuel line that is made of STEEL.

you can use a regular tube cutter to cut it square in the middle of the steel line, be sure to give yourself at least 2 inches of flat line on each side of the cut so you have room to clamp a high pressure hose around each end between your TEE fitting.


your 2nd choice is to use something like this (gold colored) adapter.....

use an adapter that goes on the end of your stock fuel rail.. It will allow you to get fuel from the rail and run it directly to the fuel solenoid ...

check out this pic:

here is a hint... the thread on the fuel rail is 3/8ths Brittish Pipe Thread !! The blue piece is an adapter for a fuel pressure guage and that is optional.
__________________________________________________ ___

Section C:
General Questions & Answers:

Q: What is the highest jetting that I can safely use on an XD?
A: Based on my experience and the experience of other XD members who have used nitrous extensively.. I suggest that if you have a stock engine, that you should stay within the 75 hp range. If you like to live on the edge, other members have used up to 100 hp jetting on their stock engine. We have not experienced any problems as a result - BUT I dont suggest going higher than 75 for consistent daily use and engine logetivity.

Q: What should I feel when the nitrous system is spraying?
A: You should feel a kick in the pants of acceleration... The car WILL move much faster than you are used to so be sure to focus on your driving. If you have stock tires, you will most likely spin the wheels in first and part of 2nd gear.. so be ready to change gears quicker than usual.

Q: I have an automatic XD, can I use nitrous safely?
A: Yes. You can use just as much nitrous as the stick shift people... Just have your mechanic add a transmission oil cooler. Total cost should be under $100 including parts and labor (if your mechanic is not a thief).

Q: Are the stock maintenance intervals affected by using nitrous?
A: YES and NO... You should change your oil a little more frequently since the engine is under more stress when you use nitrous... I suggest to change the oil every 2000 miles at most when consistently using nitrous. All of the other maintenance remains unchanged.

Q: Will I need to upgrade my clutch to handle the extra power of nitrous?
A: YES and NO. If you are using a 50 shot or less, I dont suggest it. If you are using a 75 shot or more... then you will want to get a stage 3 race clutch.. You can get a nice one from e-bay for under $300 and labor to install a clutch + resurface the flywheel should not cost more than $300 (unless your mechanic is a thief).

Q: Will using nitrous blow up my motor?
A: This is the most frequently asked question related to nitrous use. The answer is maybe. The chance of a 50-75 shot of nitrous "ITSELF" doing any damage is unlikely... BUT, if your engine is already worn out, or if it has weak bearings or worn piston rings, or a weak head gasket.. the USE of nitrous will accelerate the normal wear of those already weakened parts. So, for example, lets say you bought your car used, and you meticulously changed the oil and did regular maintenance at the required intervals... And so far, your engine seems perfectly fine... Then you install a 50 shot of nitrous and spray it once.. the next day, you hear a pinging and clanking sound coming from your engine... What could have gone wrong ? the nitrous was installed properly and you followed all of the precations and suggestions that you read on the XD site and in all the 50 billion nitrous books out there.. What WENT WRONG ?? Well, most likely, the previous owner of the car chaned the oil once every 10,000 miles... and didnt take care of it so it weakened some parts inside.. When you used the nitrous.. you pushed those weak parts to their limits and they gave out. SO, if you use nitrous, you have to be ready to face the consequences. You could be like me... use an 80 shot and never have a problem with it.. Or you could be like a buddy of mine who used a 55 shot and blew up his motor after one run.

j/p bro thats a great thread.

[2004ElantraGLS]

Damn, I want to install Nitrous on my car SO bad! Whenever I read something like this, I get pissed cause I don't have the money right now. Plus, that little voice inside my head keeps asking me "Are you sure you wanna go that route? What if the engine blows?? This is a brand new car!!"

Oh well, I don't know if I'll ever be able to drop a quick $500 into the car like that. Would be nice though....an extra 50 HP would have kept that damn CRX at bay....oh well.

Axel

[FordFasteRR]

well, nitrous has less variables of problematic issues compared to turbocharging..

its easier to control fuel and power with a nitrous system.
its easier to contain detonation due to the nature of nitrous itself..

its overall easier and safer than forced induction..

either method of adding power has its inherent risks...

its your choice of what you want to do.

:)

[2004ElantraGLS]

Yeah I know, Ford. But I can hook up a good Nitrous kit for about $500-600, whereas a decent Turbo kit will run me upwards of $3000. Even if I piece it together myself, I'm still looking at around $1000-1500.

I don't think I'll ever go Turbo with my Elantra. I don't like the cost, and I also don't like the idea of having the engine under more stress most/all of the time. With Nitrous, I'd probably only use it once a week at best, in situations like that CRX. Well actually, a Tibby swaybar under my *** would have done the trick there, but still.

Anyway, thanks for all the Info, Ford. If/when I get ready to go Nitrous, I'll definately turn to you and the others who are so knowledgable in this field.

Axel

[RabidDogBoy]

I'm debating on whether or not to go nitrous myself. It's definately cheaper than turbo and after reading this I've learned alot more about the Pros and Cons of it. At first I was skeptical because I got my Elantra used and it didn't look like the engine was taken care of but since I now have a practically new engine, and I've taken care of it, my manager at work said he can install me a nitrous kit for dirt cheap(I buy the kit of course). After reading the info about the Theta engine I'm back to the same point as before... undecided. I can wait and see or I can drop money into my car now... I'm also thinking that I can drop a nitrous kit into my car now and in a few years(when I'm out of college) I can get rid of my current Elantra for a new one with the Theta.

CAn you explain how the fuel is injected in a wet system? Also, how much fuel is needed for each hp level

[FordFasteRR]

CAn you explain how the fuel is injected in a wet system? Also, how much fuel is needed for each hp level

here is how it works... you would tap into the stock fuel sending line .. insert a TEE fitting, plumb that fuel line into the fuel control valve ( Solenoid ).

that solenoid works along side another solenoid that controls nitrous flow from the nitrous bottle.

then, after both solenoids, there are some intermediate lines that lead to a nozzle... the nozzle has openings for both the fuel and the nitrous... the nozzle is placed into a small hole on the intake tube... there are also small restrictor plates known as " JETS " that go inside of the nozzle to control the flow out of the nozzle itself...

when you activate the system, it opens both valves, and sprays the nitrous and fuel mixture into the engine to add the desired power level.

if you are using a wet kit, you dont have to worry about what size your stock injectors are... the only thing you have to worry about is the flow capacity of your fuel pump.

i suggest upgrading your factory fuel pump to at least a 190 lph walbro fuel pump (go on ebay to find it) ...

ALso, the jets go into their respective ports on the fogger nozzle.. you cant just stick them in any order you want ...

lastly... to answer your question about the 34/18 ...


the first number is the nitrous jet size. the second number is the fuel jet size... and the last number is the total estimated horsepower increase that you will get from using this combination......... refer to the chart below.

I have a GSX fuel pump right now, is that powerful enough?

[2loud2k2xd]

ford, i remember reading you lowered the fuel jetting by 3 from a 28 to a 25. what jets would i use for a 40 shot, and then for a 75 shot. should the fuel jetting be downsized from the charts above, or are the charts correct? thanks for the newb nitrous Q.

[evan938]

you know, after talkin to dave and him having me almost convinced to go w/ a nitrous set up, i was seriously considering it.

but i can not justify spending 3$/gallon for gas. maybe if prices go down, ill have to consider this

[FordFasteRR]

Well, I understand your point... But you would still have to spend the same amount of money for gas if you were running a turbo or SC anyway... :)

LOL

[evan938]

which is one reason i am semi-happy i didnt get the turbo finished.

when i started gathering parts for the kit, gas was around 150-170/gallon. even w/ premium i would have been under 2$/gallon. it seemed like a lot then, but i knew my mileage would be somewhat lower. if i would have known gas would be 3$ a gallon at this point, i would have never started saving parts and taking a hit on selling the parts i did get. i lost a lot of $ from selling those parts

[greywolf6984]

ok i was wondering about how long do you think youcan run with nitrous do you think after your car hits 100,000 that you should stop using nitrous and where can i get that stuff that you used to tap into the fuel. when I had nitrous on my car i ran a seperate line

[2loud2k2xd]

fordfasterr has the fuel rail adapters to make the "tapping" into the fuel rail easier. and if you already have 100k on the motor, i woiuld be cautious. and how well maintained was the car. all maitinence done, ect.

i now have 68,590 miles and i spray. i didnt start spraying untill i hit 60k. but my car is very well maintained.

[greywolf6984]

it has 80 on it now and I started sprying around70 but i blew the tranny already and i know why i didn't have no trans cooler on it but it did last a few shots with out it

oh yeah and the car is really well maintained... oh yeah I was thinking about blowing the motor and having hyundai replace the motor

[KeWLKaT]

HAHAHAHA you're funny lol

Question:

i am thinking of adding a small shot of nitrous on the engine, plus the turbo.

if i will be at 8 psi, would a 40 shot be overkill?

[KeWLKaT]

ok man, done :D

[2loud2k2xd]

blew up the trans already? wow, ive put 6 bottles thru mine (4 were at 80 shots) and it screams for me to drop in a 125 shot. ill do that after the new MOTOR :D is built and ready for install. a trans cooler is a MUST for nitrous and boosted applications. it cools the trans fluid tremendously. good luck on having hyundai warranting the motor and trans. make sure you remove ALL traces of the nitrous install, put back the old plugs, remove all aftermarket mods that will conflict with hyundais usual bs about parts being installed. just make it look like there was no evidence of nitrous installed. good luck man. hope for the best.

Honestly... Premium is only 20 cents more a gallon. So this summer when gas is 3.50 or so for the cherap stuff - the difference won't really be that big a deal.

alright i might bb revising a dead thread but is it posible 2 shoot the NOS into ur radiator i was reading thats what they did a while back and it sounds like it would work i mean using a dry kit spray cold air into radiator *get a new radiator and fans of course* would really help keep the engine cool along with a cold air intake well corect me if im wrong but i think it would really work

shooting nos into a radiator will do nothing for performance. sure, it might cool the hot coolant in the radiator, and some of the cooler coolant might enter the block, but what purpose or gains would you get? maby 0.0245 hp.
you might as well throw in a cooler temp opening thremostat sold on shark racing. this will lower coolant temps in the block, by allowing the therm to open sooner than a stock therm. this (imo) will do about the same effect as spraying nos on the radiator, and will cost about 500.00+ less.

[Beta2cvvt]

If i'm already on turbo at 250whp on stock internals with head spacer of CR 8.8:1, how much more NOS can the stock pistons take?

[elantragls99]

use the choke button for emergency purposes..when you need RRB..Rapid Response Boosting..LoL!

[NY2002ElantraGT]

was thinkin about S/C or T/C this winter, but i might do NOS now. How much does it cost to refill bottles? i would probably to with the ZEX wet big bottle

[evan938]

usually $3.50-$5.00/lb. which would mean a 10lb bottle will cost 35-50+tax to fill

[05xd]

Last time I filled up,it cost me 65 bucks for 10 lbs.

[evan938]

wow.

so i guess its more expensive out there. its about 4.50/lb (i believe) at jegs here in town

[05xd]

It hit a peak of 7.50 at one shop around here

[NY2002ElantraGT]

so that adds up. it would make me never want to use it. haha

[swifty]

I pay $2.75 a LB. $29.15 out the door at All Gas in hartford CT

[2loud2k2xd]

3.25 locally here

[thewilson]

Hope I don't get laughed out the door here but is there anyway to check out the engines health before installing a nitrous system? I bought my 03 used and according to the dealer maintanence was done at all the suggested intervals. Since this is my only car and I work 30 miles from where I live I want to try and minimize the chance of blowing something up. --Thanks

[2loud2k2xd]

^^
thats the chance you have to take when you want to play. if its your only car with NO other form of transportation to/from work ect, and you dont have any extra cash for another car.... i would be cautious. murpheys law can sometimes bite you in the azz. you can have the perfectly maintained motor and spray a 100 shot w/o any problems. then again you can also have the perfect motor and spray 1x and it will blow up.

i didnt start spraying nitrous untill i had about 60,000 miles. i went thru somewhere like 8-10lb bottles in a matter of 3-4 months. i NEVER had any probs what-so-ever. now i have 83,000+ miles and it still runs strong. no nitrous tho currently.

but dont let this sway you from doing something you want to do. the worse thing that can happen is nitrous/fuel puddling in the intake manifold and detonating. actually blowing up the I/M. that happend on my friends bug. certain nitrous kits are better than others. i know for certain the ZEX wet kit has a "brain" nitrous management unit. this WILL NOT aloow the nitrous to be sprayed with out proper fuel and fuel pressure. w/o proper fuel/pressure you take the chance of running LEAN and detonation will occur usually resulting in catastrophic failure of the motor.

to install a nitrous system in our cars require certain items to also be installed. a better clytch (if you have a manual), a trans cooler (auto trans cars), fuel rail attatchment (which makes tapping into the fuel rail much easier--sold from fordfasterr), the nitrous kit --actually a WET nitrous kit), and a good knowledge of wiring and basic mechanics to do the install. i have a DIY on a nitrous install in the DIY section. step-by-step install guide.

[thewilson]

I want to thank you for this great information. The "brain" reduces the chance or prevents detonation? I am thinking I'll be doing this with tax return money if nothing expensive breaks around the house. What is a reasonable estimated installation time for the Zex Wet kit and a transmission cooler? Anyone have any part numbers or recommended sites that sell either of these products? Thanks a milion 2loud2k2xd! :nosthumbs

listen to this guy as well. he is another nitrous GOD. and dont forget you WILL need a fuel rail adapter...also from ford..if he still has acess to them.

part #
hayden trans cooler #1401 about 25.00 shipped from ebay
zex wet nitrous system #82021 about 500.00 shipped from ebay, it may be less. i would check the tib sites as someone may be wanting to sell their old kit.

and yes, please do alot of reading on nitrous on this site. most everything has already been discussed. dont forget to get new spark plugs. 1* colder plugs. ngk bkr6es IIRC

as far as install time. it took me + a friend about 8 hrs to install with beer brakes and a couple 420 breaks :). i also installed a LED (red) machine gun rapid fire purge kit, made my own custom bottle mount, installed a dual gauge pod w/ nitrous pressure and A/F gauges, installed the purge switch, got bottle fil;led, and went on 3 test runs (1 st test run to make sure nothing blew up, 2nd me vs friends 90 5.0 stang (lost), me vs 03 tib gt auto (i owned it).

Alright folks where the heck can I buy some nitrous oxide I started working on the installation and then I realized I have no clue where to buy nitrous oxide from. Any tips or hints or ways to find someone who sells the stuff?

Thanks

ps i'm still using the nitrous guide thread because Im sure someone researching the use of nitrous will have the same question and this one is sticky
