just wondering how the 7A-FE would handle a 50 shot or so.
who's got NOS? - 6G Celicas Forums
Well, I just wanted to correct you in a helpful manner. I personally don't have it, but I'd like to give you some information. NOS (Nitrous Oxide Systems) is just a single brand of Nitrous kits. There are many other systems, such as Venom, ZEX, and Nitrous Express. So, if you say NOS you might send the signal that you only want people who have that kit in their car, and someone that has a 50 shot of nitrous from a ZEX kit might not reply.
Also, if I were you, I would think that a 50 shot in a 7A-FE would be ok, but only once or twice, not very often. Maybe I'm wrong, but I'd definitely look into it thoroughly before attempting it.

...oh man!
sorry for my incorrect term of Nitrous Oxide. forgive me for thinking that saying the word "nos" everyone would know what i was talking about. my bad.. i guess.
now, back to the subject, i was thinking of getting a Nitrous Express Kit for my ST but only squeezing a 50 shot. no more and no less. how would the engine hold up to this. what kind of ignition tuning would i have to do?
the 7A-FE is so weak i now must resort to NO2

Not to be an ass about things, but NOS is a brand as well as the abbreviated term for Nitrous Oxide. So asking about NOS, wouldn't drive away people who have a ZEX kit.
Anyways, if you don't have the money to buy a new motor, don't even attempt NOS. You'll blow your motor after a shot or 2. And if your motor is that slow, you'll wanna use NOS more often then not.

Well, a little off your question, but I have a question for you. How much money are you willing to spend overall? Because, even though you can get many squeezes out of a kit...in the long run, it won't really help you that much at all. Sure, you could say you beat the guy because you have Nitrous. But, you could engine swap and say you beat the guy on all motor.
By the way, if NOS is an abbreviated term for Nitrous Oxide..then why doesn't Venom have a Venom NOS kit? I'm pretty sure they have a Venom Nitrous Kit. What would the S stand for if not being the brand of Nitrous Oxide?

who cares about the terms or abbreviations i know people know what i'm talking about when i say NOS. you did, inferno.
I know I did, I was trying to help you though. Some people get iffy or whatnot and get mad when people use the wrong terms.
oh well, no big deal, right?
Right. >

so, isn't there a saying that all engines can handle a 50 shot?
Not all engines.
i guess that means not the 7A-FE also. what a downer!
go ahead and get a 50 shot
but get a compression test and make sure your engine is in good shape before youy start to beat the **** out of it
you can even go for a 75 shot if you want. just make sure you dont lean out.

what is stock compression on the 7A-FE anyway? and even if my motor is in good to even great shape, a 50 shot is still concidered "beating the $hIt out of it"? then what about a 40 shot or a 30 shot? i don't even know if those are noticable gains once below 50.
From what I've always read, a 50 shot isn't going to kill your engine at all. Just make sure you don't spray from like, San Fran to Chicago or something.
Nos is getting to be the term for N20, like Band-aid for Medical Adhesive or Kleenex for tissue. But show your smarts, say N20. (or it might be n02 I always forget)

dude, i had a 90 shot on my 7afe with 150,000 miles on it and it was fine. just make sure you retard your timing before you go out to race.
ya it would be NO2 ...nitrogen has an oxidation number of +4, meaning it will take two oxygens (with an oxidation number of 2-) to create a stable molecule........................ >

i hate it too, i just took the AP Chem exam two weeks ago and it sucked really bad.
the CR on the 7afe engine is 9.5:1. one of the many reasons why the engine lacks power

how far would you retart the timming for NO2?

that's the way cause now I'm running 14:1 CR on my 7afe >

how did you do that? you can't possibly shave the head and deck that low and i know you can't use any adjustable cam gears for our ST motors, can you?

Heh...how the f*** did you manage that... custom ****s? Too much work and too expensive for me...
As far as nitrious goes, NOS isn't an abbreviated term for anything but NOS (the company that sells nitrious systems). The correct abbreviation as mentioned is No2, 1 part nitrogen and 2 parts oxygen... or some shiat like that. The 7afe can easily handle a 50 shot... Just remember, when you spray... be responsible.

I got that impression also... I think he doesn't know what he's talking about... but if he/you do/does have a 14:1 comp ratio... then...well... musta punched the pocketbook pretty hard. I mean...damn... costs more than a swap or a custom turbo to do head work and block work like that... especially on the 7afe.
The 7afe and the 5sfe both only have a single cam sprocket (although they are dual overhead cams). It's part of the "fe" head designation. Narrow head design, better economy, poorer performance, blah blah blah... so in other words, no cam gear"s"... ;]

ok, just to explain:
I've done the work myself with a friend of mine who is a mechanic.
you can lower the head of 6/10 of millimeter without having valves touching th pistons.
I paied nothing to do the job to the head, including P&P.
In Italy we have 98 octane fuel at pump stations and I use it and have no pre-ignition problems.
In a few days Iìm going to a MSD ignition and Denso iridium plugs to manage it better.
x Kwanza: you can have adj sprockets, OBX make it but is hard to have....anyway you can have one custom made....a friend of mine got it for just 50 bucks...the use your original external part of the gear, where the timing belt is on and rebuil with ergal parts the gear interior to make it adjustable.

Interesting...when I had my headwork done, it costed over 800 dollars, just for a complete port/polish, valve retainers, springs, etc... Mentioning high compression, I would figure to push a 14:1, you'd have to use high comp pistons. There are high compression pistons for the 4age, and they do fit in the 7afe block, but the rods are .2 stroke shorter... so custom rods will have to be made, installed, and balanced. That kind of custom work for an all motor set-up is highly expensive.
As far as there being an adjustable cam sprocket, sure...why not... I was mostly nagging about everyone calling them cam "gears" when there's only a single cam sprocket... As far as OBX goes, they make a lot of claims about products they "supposedly" have, but try calling them up, and they'll always tell you, "it's in production..."
