my zex nitrous attempting thread. Options

[terbear4god4life]

i recently have picked up a full zex dry nitrous kit with all the goodies im starting the install today but over the time i will keep this updated here and will be taking pics


my 5s has 240,000 miles but still runs absolutely perfect i have no idea of past events or anything internal done to the block other than it has a new timing belt so i like to think the previous owner had replaced the head-gasket too.

i know a bunch of you think this is a bad idea but i don't have the resources or time or money too rebuild or too swap or boost like a lot of individuals on here.
so this thread is for the truth behind our cars on nitrous




will keep this updated

hellz ya. good luck man, i'm interested in the results

[Espo]

If your engine goes, might as well go for a 3s - I hear those handle chemical induction on occasion with no problem.

[conus00]

How many shots are you plan on running?
At minimum I'd recommend to upgrade your fuel pump.
I'm also not sure how kindly will stock tranny and clutch take all that extra torque...

[terbear4god4life]

right now all i have is a 75 shot that im keeping for the track and im getting a 35 shot for the street

as for the tranny i plan on granny shifting haha and my clutch is a exedy stage 1 so it should handle the power..the kid i got it from ran it threw his 93 celica st at a 75 shot and said it went perfectly fine so im not all that worried im not one too overuse anything

was busy much today so the official start day is tomorrow lol

and also, im going to record my first use of it so if it blows ill have an epic video

Great! I'd love to see if this is fact or fiction that your motor will blow at the first shot of nitrous. Personally, I believe you'll be fine, especially with a 35 shot. Best of luck to you. Looking forward to that video of your Celica hitting light speed when you hit WOT.

[terbear4god4life]

would i be allowed to post a video of it on here?? as long as it isn't street racing right?

[presure2]

yup, post all the videos you want, as long as your not street racing, or being totally stupid, your fine.

cant wait to see this man. Im glad you are taking the opportunity to do the things people say you shouldn't. Go ahead and prove them wrong....

If only someone would do the same with the 2jz in a 6gc. lol. that would be the day......................


btw im not being sarcastic, hope it doesnt come off that way... , i really want to see you beat the odds.

lol agreed! the bottle would be a nice smack on the head

i don't suggest anyone mounting one were i did..i barely missed the gas tank putting the mounts in..

but i do have too admit if someone tried too set my car on fire they would get a nasty surprise

cant wait for vids!

[terbear4god4life]

also my pointless keychain thing came haha.


let me tell you this thing is awesome.
real carbon fiber layers and everything for about 6 bucks.






so worth it.

[terbear4god4life]

no updates for today still raining and sh*t but tomorrows a new day!

[terbear4god4life]

another crap day

thanks global warming!

[dans_st]

first off....

WHERE'D YOU GET THAT KEYCHAIN???????

secondly....
I had nitrous before on my celica, 50 shot, rans strong all day, 75 shot, before bottle was empty i had spun a rod bearing

BUT, I think it was my own fault, I didn't know enough about nitrous back then, and hope you can learn from my mistakes.

1st
wet it better(adds in its own fuel and is safer)

2nd
MAKE SURE TO RETARD TIMING!!!!!
if I were you I would buy a mallory 6A that has window switch and timing retard, AS WELL AS MORE SPARK(about $200)

3rd
go get you a set of 1 step colder NGK plugs like BKR7ES-1 should work fine for your 5S

my car has 76,xxx miles on it, but they were really hard miles and I didn't take the precautions mentioned above, at very least I would do the colder plugs and retard the timing some.

[Smaay]

i highly suggest getting a wideband O2 sensor and watch the airfuels while squeezing. you can get away with a dry kit because the 5S has a return system, however the MAP sensor is going to go nuts because of the pressure you are inducing.

i might lower the shot because i still want it too be peppy without it..
zex says i don't need to retard it for a 55 shot so i might just go with that

how much difference did the nitrous make when you ran the 50 shot?? like will i loose a second with it you think?

i have a fuel pressure gauge and exhaust temp that im going too pay wayyyy close attention too hopefully that will be enough

well if you mean on 1/4 mile, a 50-shot I think will only get you a max of ~.5 sec, someone correct me if I am wrong?

Also is your ZEX kit the one that has a vacuum line that connects to your FPR?

if so that one is way better because it ups the pressure and richens it up a little.

yea that's the zex kit i got will it keep it rich enough for a 75 shot too last a while?? if only used rarely tho? or should i just be safe and try to find smaller shot jets??

good advice. i always hear that wet nitrous is better than dry. colder plugs are a good idea too.

[lagos]

This is pretty much why people blow their motors. They skimp out on things like a wide band, and then wonder why their motor blow. Same thing used to happen in the 5sfTe community years ago. Everyone one would install the turbo but never bothered to monitor their air to fuel ratio, and then wondered why the 5sfes would blow up after a month of boosting.

Get a wideband.

im pretty limited by funds..

i mean sure i could do it right get a wideband get a air/fuel controller and than go get a tune for the nitrous..

from what iv seen people have had the most luck with a 55 shot so im attempting to find the jets..
i believe in my handy work and i can tell if im pretty much running lean or rich with the gauge..personally in my own sense if the fuel pressure drops im backing off the nitrous really quickly!

[JoKeRkId613]

if you have limited funds, wouldn't it be wiser to wait til you can afford a wideband before blowing your motor and having to wait for funds to buy another motor when that happens? your handy work isn't going to save your motor. get colder plugs, tune it, do it right. that's a lot of mileage.. good luck either way.

[terbear4god4life]

well im hoping too just shed light on all the doubt..

if a stock 5s unopened can handle boost at 250+hp it should be fine with a lil 55 shot...well see tho!

This post has been edited by terbear4god4life: May 20, 2010 - 4:08 PM

[95st-celica]

your gonna blow your motor homes...

if you cant afford a $175 wideband, your not going to be able to afford a new motor/car/other mode of transportation after it does blow.

listen to the advice that these guys and i am giving you...i know your anxious, and you just want to jump right in and start spraying...but if you wait that extra week to get the money up, and buy the parts you REALLY need, it will be the difference between spraying for a weekend and spraying for a few months.

in my oppinion the 5s can handle a 150 shot unopened, but thats with all the supporting mods, such as a wideband, an SAFC, FPR, colder plugs, timeing retard, oil pressure gauge, and a nitrous gauge. If i were you i would have bought all of that FIRST, then buy the bottle, that way your not going backwards.

i wish you all the luck man, and if you can get away with a 55 shot untill you get a wideband then thats great...but your motor wont like it at all, espically with almost 250k

[terbear4god4life]

as of right now all i need is other jets preferably 65-55 shot....
a blowdown/blowout tube
and a fill


if the motor goes it gives me inspiration too swap too a 3s



the kid i bought the nitrous stuff from ran the 75 shot threw his 93 celica st and it has 180,000 miles on it and he said it ran absolutely fine..


im not that concerned i have a nitro/methane mix i will mix in with a full tank before i use..

[terbear4god4life]

it happens that the jets i have are for a 55 shot

and i got all the electronics are installed

so im selling my hood today for the blowdown tube.


next weekend hopefully it gets here so i can spray

im gonna take a bunch of pics try to create a write up install for a 5s


and the video will come too

im not that concerned i have a nitro/methane mix i will mix in with a full tank before i use..

IMO thats a VERY bad idea.
nitro/methane is basicly adding more O2 to the mix, which is also what nitrous does.
you need to be adding more fuel to the mix, not more O2.

my 5s has 240,000 miles but still runs absolutely perfect i have no idea of past events or anything internal done to the block other than it has a new timing belt so i like to think the previous owner had replaced the head-gasket too.

i know a bunch of you think this is a bad idea but i don't have the resources or time or money too rebuild or too swap or boost like a lot of individuals on here.

So what I am getting from this and your other posts in this thread is you wish to provide us with no actual data? Just a "hey I blew my motor, no I have no clue why, I don't know what my AFRs were, no I didn't track data"

So the whole point of this really isn't the point. The point I am seeing is that you want an easy go fast car without any extra hopmework or effort, yet you admit you have no budget and still are willing to blow your motor for no actual point.

Well good luck. I am hopeful for your motor and car. I have done the same thing you are doing but with the turbo about 8 years ago. I did it on my daily driver with no budget for all the proper stuff. The motor went pop.

Please head the warnings of others.

[terbear4god4life]

ill try


itssss all ready!

ill take pics tonight im gonna clean it up

thanks for that info or i prob would have..

whats the status on this? any update? im curious to see a video of you spraying and what kind of numbers the car is putting down with the nitrous.

UPDATE!

[EKAn]

I'm excited to see this thing in action, Vids!

UPDATE!

Its been almost a month since he said "Next week"... so I'm really hoping his engine didn't blow up on him... that would be a tragedy.
