Vafc Is Only For Honda And Acura. It's Made A Car With Vtec.

Um... Nissan Cars Don't Have Vtec. I Wanna See How You Gonna Use This Vafc. If You Already Bought This Product And Was Planning To Use It On Nissan Car. Good Luck. I Noe You Gonna End Up Returning That Product.

Let's Say It Was Vafc Was Better Like U Said. How Come None Of Fixed Up Supras And Skylines Have It??? Dat's Right It Only Wokrs With The Cars With Vtec.

Safc Ii Is The Way To Go Man.

Don't Ever Post Something Stupid Like Dat In Da Future.. Thank You.

Then I suppose I have installed VTEC on two different Maximas now.


You really should make sure YOU have the correct info before you call someone else 'stupid'.

BlackMax06

A VAFC will control any motor that has variable valve timing. All that little nifty device allows you to do is control the point at which it occurs (like on a honda, instead of vtec at 6000, you can change it to 4800, trust me I know, I just sold my turbo integra.)

As for the original poster: Of course you will notice a difference performance wise with the cams, I cant speak for nismo/stillen cams or any other cams for that matter, I just purchased my first Nissan and Im still new to the field of VQ's and Nissans in general, but I know on most other cars, along with the purchase of cams, you will need some mild tuning to get the idle right among other things. I would hate for your idle to go to ****.

Good Luck.

No it won't. And that isn't even why you would install the VAFC2 vs. the SAC2 in these cars.

Aiite. You Can Install It But Withought Connection Vtec Solenoid Wire. Cuz That's The Whole Point Of Having Vafc. I Have Two Constant Adjustable Valve System. It's Totally Different From Vtec. I Have Two Lobes On My Cam. Vtec Has 3. Vtec Uses The Solenoid To Change Oil Flow To Other Direction To Enable Vtec.

So Without Connecting The Vtec Solenoid Wire, It's Identical To Safc. Vafc Ii Also Allows For The Vtec Engagement Point To Be Manipulated From 3000-7000 Rpm, Including The New I-vtec Systems, Vafc Has More Functions, Because It Have Vtec Engagement Point Change And Unmatch Fuel Control..

Ok Sr20den.

Let Me Ask You This.. How Do You Hack Afc, If I Have Different Injectors?

SEXIMA04

iTrader: (2)

Variable timing has many different ways you cant change your VQ engine timing with honda way. Honda use changing of oil line to enable vtec
and VQ advance your timming with cam angle wire you are running
so VAFC Vtec fuction won`t work on *^&%$ nissan cars. y won't they use vafc cuz it don't work.

like i said.. you can install it but it's gonna be identical to SAFC. believe wut you want. and do wut u guys want. it's just an opinion. i am not trying to fight here. just trying to help. if i wasnt much of a help then my bad.

take care.

I just received my SAFC-II and wish I had read this thread earlier, however the SAFC will still do good things and whatever someone chooses for their ride is up to them. Looking back at all the info, yes I may have gone with the VAFC for it's noted advantages, however no one downplayed the advantages of a SAFC-II that is dyno tuned to your vehicle.

Be cool and turn the caps off, it's annoying. Sometimes it's not what you say, but how you say it that will get you heard...

AzNx2k2xSEXima

actually ur not in the right place to call people dumb. i believe that my friend sexima 04 was the first of alot of things in the 6th gen max's.
i dont see any of you pu$$y *** bitc*es dishing out the doh to try new things out just to benefit others on the forum. all your doing is *****ing at my friend here.

after reviewing your links, the only difference that i have found b/t the safc and the vafc is the 12 more points for fuel, and a vtec engagement switch.
i highly doubt that there is a huge difference by engaging the butterfly valve a little earlier. what like a 1 or 2 hp difference.
Y DONT ALL OF YOU JUST ATTACH A STRING TO THE ****ING VALVE AND OPEN IT YOURSELF FROM THE CABIN, YOU'LL SAVE HUNDREDS OF $$$$.

SR20 what have you contributed to this forum except the "wasting of time"
do you have an SR20

i currently have a s14 sr20det along w/ a max and a xterra.
so i do believe i know what i am talking about. not to mention "eric" my buddy to also posted on my friends sn "SEXIMA" have worked for race shops, and have done countless modifications ranging from your POS EG to you W202.
if you have anything that i wouldn't know please enlighten me. but dont post up "VAFC>AFC" explain yourself in the same post. man...had to read all those stupid posts just to find out 2 lil things.

WASTE OF FUC*King time. people say u know ur ****.....PROVE IT. DONT PROVIDE WORTHLESS LINKS.

what does any of this have to do with you? your sexima friend (nice names) came on here calling names and proving his ignorance saying

he was proven wrong. it makes no sense and is disproven by those with the VAFC on their Nissans. HE IS WRONG.

Glude

iTrader: (5)

Exactly, and he started all this by calling me dumb. I was in no way trying to disrespect him but obviously he decided to get bent out shape and whine to his friend because he was proven wrong. Im not doubting that hes doing good things for the 6th gen, its very impressive that he has installed headers. I knew they would fit with modification, but I have a job and dont have time for messing with something that almost fits. Next time you jump on someone for something, make sure your right first.

logik05se

nissan uses continuosly variable valve timing system, except we call cvtcs, and honda calls it vtech. correct me if im wrong but arent they pretty close to even the exact same thing?

AzNx2k2xSEXima

ok guys....theres no point in calling people dumb.
but there is a huge difference between the honda vtec and nissans cvtc.
THE BIGGEST difference as stated b4 in the thread is that honda's vtec actually switches CAM LOBES. creating the best of both worlds. conservative at low RPM and real aggressive at high. the whole thing is controled by a solinoid that switches the heads...dang...can't eplain.....need to draw it out. but the NISSANS ONLY switch the timing of that cam and they added the lil butterfly valve in the manifold which seems to be the WHOLE PURPOSE for using the VAFC. this didn't give me any gains when i was messing around w/ it. THIS is no where comparable to REAL VTEC.

i was kinda pissed off that u guys were harassing my buddy. He isn't too fond of this forum in the first place. Not to be *****ing at u guys but u 6th gens need to man up and start testing out more ****.

DONT TALK ABOUT HAVING A JOB and no time. We didn't pull money out of our asses to be able to do all the mods. we have jobs too. so thats no excuse

AzNx2k2xSEXima

dude....did you NOT read what i said..... JUST BECAUSE you have alot of post duzn't mean u know all your sh*t.

Sorry but my car isnt my life and I never said post count meant anything. Obviously you pulled that outa your *** because I never said that. Do you have something to prove?

You've been here since 2002 and you're asking a question like that? You need to read around a little more.

No one is going to spoon feed you, esp not with an attitude like this. Links have been posted, and all you have to do is read and comprehend.

SR20DEN

iTrader: (7)

The facts start and end with this statement.

There is actually NO gains to be had at all by changing the active point of the power valve.
Point missed again. Please revert back to statement #1.

There is a whopping $5 difference on Ebay between the SAFC-II and the VAFC-II. However, I doubt your string method will impress the dyno or the cars that just beat you at the track. I'll take my chances with the computer that can surely do the math quicker than me, while I tend to more important things , like driving the car.

In your case, apparently nothing.

No. I sold my SE-R several years ago. It was along time ago when I would build them, back when Internet forums such as this did not exist, or your drivers license.

I am happy for you, and the several thousand other people who have them too. I never had the luxury of following in someone else's footsteps when I was owning all the local Hondas at the racetrack. I had to figure everything out for myself.

What exactly are you talking about?

If you want some credible recognition, that certainly won't do it for me. There are more bad shops then good ones.

I tried. I posted several links that show I have beaten this subject like a dead mule, trying to educate everyone as to which product is the better buy. And yet all you seem to want to do is complain that I haven't done exactly what I have done.

Point missed again. Let me ask you this, since you seem to be the most patient and forgiving person in this forum. If you discovered something that could be potentially valuable to this community and you posted that info about a dozen times within the span of a few months, would it not tire you in the least that many people still chose NOT to put forth the effort to find this repetitive information? I do make a conscious effort to help people on here. And even with my short temper and lack of patience when it comes to repeating something for the tenth time, I think I do ok.

I did however provide the links that showed where this information had been repetitively provided. I didn't see the need to explain in detail that information. And I didn't use the old .org method which would be to tell you to search for it yourself and help you no further.

You're welcome.

And I am eternally flattered.

I thought I had. If not, then why would other people say so?

And in exactly what other way would you suggest I do this? I suppose now that my life will revolve around meeting your approval I will either have to ask you to move to Charlotte or I'll have to move to you. I just don't see any other way to prove my worth and loyalty to you if you won't accept my literary English. And I can't type it in any other language. I do know a few words in Vietnamese and Cambodian, but those words aren't exactly ones you should be using in public, or to your local preacher.

And I hope you do well. I just pray they have nothing to do with reading comprehension because you may just have an exhaustive uphill battle on your hands.

You've finally said something that I can agree on.

Wait, I recall something about someone working at a race shop.

So you own a riced out 240SX with a engine swap.... uuuu aaaa. I've rolled around in SR20 powered Sentras before you started grade school. At the same time since you have a SR in your car this must mean you know LOTS bout them eh ? You would probably know that the KA24 that your car came with is a MUCH better starting point than the SR also... I don't work at no race shops, I work for a CAR dealer. I also built ALOT of fast Nissans and Hondas for less than your engine swap cost. If you read the links provided you would know WHY VAFC is a much better piggy back compared to the normal SAFC, but since your intelligence challenges that of a water mellon I will leave it at that. I love going to "race shops" just to see what kinda BS they will tell me, how I am wrong and they are right. I have YET to find a rice shop that knows WTF they are talking bout, most of them are ran by a buncha lil kids who have a combined IQ similar to that of a orangutan. Atleast orangutan has a better hair style than those lil hair gel punks who know all....

theres a 2 stage vtec found on the b18c1 motors, 1 stage engaged with oil pressure and the other engaged with a butterfly(vacuum)this butterfly method is also used on the v6 vtec's as well. some of them at least. most are a single stage vtec using the oil pressure. im not sure how the nissan varible valve deal works cause im new to the max. i came out of a 95 civic hatch running 10psi through a b18c1 stock bottom end motor using the V-afc hack on 440cc injectors. would the V-afc work with the nissan the same way as it would with the VQ, i dont think so. different setups.
