Well, the bottle should always be opened fully, but that's not why you're not feeling it. Just recap, what type of kit are you running, and where did you place the nozzle? I wasnt going to get into nitrous debates here anymore, so stopped posting, but it seems like you arent getting any help from the "SL Experts".

Maybe I can help you out. As soon as you're running right you'll be a junky.

 

where in flordia are you located? I've done tons of nitrous kits... LMK if you need help

 

im in kendall miami, basically i have the zex wet kit 75 shot, and i have a purge kit as well. the bottle is in the trunk and its facing exactly how it should and its 15 degrees up, all the lines are correct, no leaks, and i checked the purple box and it turns on when i flip the switch so its weird.

 

Well, that's your first problem...ZEX.


1st, how far is the nozzle away from the TB? Is it aimed at any sort of angle, or strait in?

2nd, Are you sure you havnt been cruising around showing off your purge and didnt know your bottle was empty? It will still cloud with low pressure. If you dont have a gauge the best way to tell if you still have gas is to throw it on a digital bathroom scale. The bottle weighs 14 pounds, and you should have at least 4 more pounds of gas to even be effective. I'm assuming you dont have a heater.

3rd, Is there a puff of black smoke from the tailpipe when you engadge the nitrous? I have an idea you are running very rich. This could be a couple things...ZEX is a universal kit with very safe jetting. This is for dumbasses so they don't lean the mixture out and burn up the car. Every car is different, so there's no way to get a perfect jet setting for everyone if it's universal.

Have you pulled your plugs to check for lean or rich condition? Reading the plugs is still the very best way to tune a nitrous car. I've made more power with the correct jets set at 50hp than most universal kits make at 75. Ask anyone that bought my kits...they hit hard. If you dont know how to read plugs snap a picture of the #1 and #4 plugs and post it up.

4th, Do you have an inline nitrous filter?

5th, Are you sure that pathetic little nitrous solenoid is actually working? It's hard to tell, cause it's hidden in a pretty little purple box. Pull the intake and test fire the system with the car off. Make sure everything's aired out before you reinstall it and run the car.


Lastly, why are you starting out with a 75hp shot? It's just a baby shot, but it's still enough to hurt your car if you dont do your homework first. I always advise you start at 35hp. At this level you almost cant even hurt anything even if you do everything wrong. Throw those little jets in and I'd be willing to bet your car runs just as good if not better than the 75. Play around with it and try different fuel jets...richen it up and check the plugs after a bottle so you know what rich plugs look like. Then start leaning it out slowly until your plugs are perfect. When you have that down go to the next level.

It will take time, but once you learn the tricks you got them for life. There is an art to running a nitrous car. Dont expect some candyass rim shop to install your stuff and then go out and beat on turbo cars.

Keep us informed on your progress...if you do it right it should take you a little while, but it will be well worth it as you walk all over cars that never suspected your quiet little tC had anything.

 

very nice kapthowdy!

1. the bottle is in the trunk and it should be a straight line to the intake since the bottle is facing straight.

2.i just recently filled the nitrous in and i havent used it much now, i dont really need a heater here in miami since its basically hell conditions lol.

3.i never really checked if theres black smoke coming out of my car, i chenged my plugs to copper ngks 1 step colder than stocks since thats wat was reccomended to put for the nitrous. i should still have the stock plugs if you want me to take a pic of, idk which was 1 or 4 but i did have them on when i used the nitrous.

4. didnt see the inline filter on my kit so i doubt i have it.

5. i never tested the system that way before, all ive really done was put the car in neutral and revv it up and u can feel the intake metal get a bit cold.

I started off at 75 because thats what it came with, i have the 50 jets but everyone was telling me to stay with the 75 because it should still be safe, so ur saying i should get different fuel jets? do i leave the nitrous jet at the 75? or should i just leave the 75 nitrous jet on and put the 50 fueljet on?

I appreciate the help man

 

Ok...

1. I wasnt talking about the bottle. I'm talking about the fogger nozzle that you had to drill a hole into your intake plumging in order to spray the mixture into the throttle body.

Your nozzle should be about 6-8 inches from the TB, and for some strange reason tCs like it better when the spray stream is slighly angled to one side...maybe 15 degrees from center.

2.if you had a heater it would maintain pressure in the bottle until it was empty...as it is your bottle has more pressure in the heat of day than at night. You can actually feel a differance between hot and cool bottle pressure. If you dont have a heater expect the "hit" to be weaker the less gas you have in the bottle. If the bottle is around 3 pounds or less you will have very little "hit" unless you have a heater.

You dont NEED a heater, but it should be one of those things you pick up next. It will save you money, and you'll run better.

Also we have established that you do have a good nitrous charge.

3. NGK Coppers are what I use...I like them because they get the job done, and they are cheap. You'll go through them pretty quick depending on the amount of usage and tune of the car.

Pull the #1 plug and check the color. I'm sure you can find a chart online for reading plugs. If it's black and sooty, then you're pig rich, if your white and chalky you'e super lean, and should stop use right away. What you are looking for with a good tune is a light mocha brown with little rust deposits. It's hard to explain, but if you need to send me a picture and I'll read it for you...or look it up online.

4. Get a filter...debris will enter through your bottle and may either clog the orifice and starve flow, or lodge in the solenoid plunger area and and stop the plunger open causing a leak that may damge your motor. We've already established that you have flow, but it's a cheap precaution for the future.

5. NEVER spray the car when it's not under load. No neutral spraying! Do it with the car off to test.

6. Stop everything till you can get to a speed shop and buy new jets...after you're done you'll have a nice collection in your tool box.

Buy a .030 for nitrous and a .017 for fuel and be sure they go in the right ports. This will net you around 40whp with a high flow bottle and 900psi of gas. I have used this in my tC kits for a very healthy 35hp shot. If your system is set up correctly you will feel more of a hit with these jets than with the current ones you have. I promise.

Lets recap...buy the jets ($3 each), an inline filter ($30), and a new set of plugs ($...pull the old plugs and inspect them. Let me know what they look like. It doesnt matter, I'm just curious. Install the new plugs and jets, make sure your bottle is full, or close to it. If your fogger nozzle is positioned correctly you should feel a differance on the first hit. Use the entire bottle. Pull the plugs again, and you'll see what they are supposed to look like.

With this exact set-up and an exhaust I have personally walked all over a buddies TRD SC tC (I'm talking BAD), and run door to door with a Stage 0 ZPI tC.


No offence, but you're the guy who gives nitrous a bad rap...you need to do more research and focus on what you're trying to do. These badass turbo set-ups either come from fellas that work hard to understand every facet of there project, or guys who can afford to pay someone else to do it for them. Nitrous is the same deal, just alot easier to get into. I think that's why most fellas take it lightly, then end up with a broke car.

We'll get you straitened out, just dont take it lightly and do the research.

 

lol i appreciate the help man, trust me ive been trying to find info on nitrous and how its to be used and everything but im finding out little at a time, im going to the library or the speed shop to find books on it.

so basically tomorrow you want me to go buy a .030 and a .017 and than try it out and than read the plugs to u? also do you want me to read the plugs before switching to the new jets? even if my plugs are new u want me to get another set?

 

also make sure u got the jets matched up right.

 

Yes, start with fresh plugs and the new jets...this is so you can get a good read on the new jet settings. Remember you're trying to learn how to do this right, and this is the only way I know of if you dont have a wideband or lots of cash for dyno time. It's how I learned 15 years ago after leaning out my first nitroused 5.0.

I can and will give you all the correct jetting for any level and mod you have on your tC, but in order to retain all this stuff you should start at the beginning and work your way up. This way when you decide to buy a more potent car you'll be able to work it out on your own without wandering around boards asking for help that not many are qualified to give you.

Believe me when I tell you that you will be impressed with the jetting I gave you. And starting out at a 35hp level is easy on the car. Whoever told you that a 75hp shot is safe for a novice is incorrect.

The first nitroused tC I worked on a couple years ago is owned by a kid called nitrousNate. We installed his kit and he was nervous, so I took him for his first ride. Found a nice looking 87-93 Fox Mustang GT vert and revved on him. Mustang guy just laughed and punched it! With a 35hp jetting we put 2 lengths on him from 45 to 60mph and he wouldnt play anymore.

 

lmao nice! ok today i went to the speed shop and they had a 32 and an 18, so i got those, i put them in and i looked at the 75 jets and noticed they were the copper ones, also i checked my spark plugs and it was perfect, it was a light mocha color just like you said, i did not see any bluish color or black on it so i guess its good. and i tried the nitrous out when the car was on and it worked, so right now im gonna go out and give this thing a try wish me luck

 

Great! If the nozzle is correct you'll run quicker than before. I'll be here waiting to see what you're doing.

 

yesss the nitrous worked man, i even heard it shooting in the intake a bit, i felt a bit of a push and got to 80 mph pretty quick! my question is why didnt the 75 work?

 

oh also whats the next step i should take and when should i do it?

 

That's just what you get for buying a cheap POS kit. It's not made for your car, and there's a big issue when you're using more than a 50hp shot on this car with the generic set-up. Contact me at Kapthowdy at Gmail . com or here through PM to work out the next move.

I'll help you out cause you seem like you're eager to learn and polite. Anyone else that pumped me for info, then bought a cheap kit from a drop shipper or (God forbid) Ebay can just bite me. Of course all my customers are always welcome to get a hold of me if they have any problems, but they never seem to...their cars run perfect.

I dont play with Scions anymore...my wifes car is very quick, and I'm back with Mustangs now...those fellas dont have a kitten when you tell them how much it costs to go fast.

 

appreciate it man, i sent u a pm

 

When you're done you need to bring it up to Orlando on a Saturday night for some testing...

Just got a message from one of my boys that said he MURDERED one of the local ZPI Stage 1 cars here 3 times in a row with his very mild SuperFa nitroused tC. This was in front of many other members here, so there's proof. No timeslips, cause it's on the street.

Almost makes me want to buy a tC

Wont say who's cars they are, but they might...they are both members.

 

thatd b sweet, theres some turboed cars here that i kno of that i wouldnt mind going up against

I havent been on here for a while, didnt mean to abandon you. I'm glad to hear you got it working. I seriously thought you were going to blow your car up.

 

lol why would u say that?
