I was just curious to know if that theory about running the blow thru maf setup really works and allows us to run OPEN bov without having any stall problems during shifts or even comming to a stop light... Basically we would put the maf on the cold pipe, and place the bov on the hot pipe. Once the b...

UPDATE: I raised the idle to 1000 rpms and that did NOT help. The motor still stalled out. A guy on freshalloy wrote me a nice PM telling me what my problem was. The problem IS the bov dumping to atmosphere. So I asked him WHY is it that when i recirculated the bov it did not help. Well, simply beca...

Ok, after months of searching i found out from others that the entry method for the bov going back to the intake side does not matter. It does matter for the wastegate entry back to the exhaust stream. I had it 1st routed into the exhaust stream at a 90 degree angle and it caused boost creep. I then...

Well, after everyone insisting that my stalls were due to open atmos bov, i went and recirculated it back to the turbo intake and im STILL STALLING out..!!

That was a waste of $30...

Anymore suggestions..??

VERY WEIRD..!!!

I have that same problem and they ALL told me it was due to my OPEN ATMOSPHERE bov...
So i went out, got the materials, and recirculated my bov like they said to.
Guess what..??

IT STILL STALLS OUT..!!!!!!!!!! So much for that..!!

Why would leaks down by the turbo or manifold cause a mis-fire on idle..??

The ONLY vacuum lines i have on my manifold are the Brake booster, Fuel pressure regulator, BOV feed and my boost gauge feed. Thats it..!! My recirculation adaptor for my bov will arrive here tomorrow but i dont see how that will cause backfire on idle, NOR make my idle jump between 400-1000 rpm.. M...

Ok, after letting the motor sit overnight to cool down, i started it back up today. It idle'd fine and smooth for about 2-3 mintues. Then the mis-fire starts up. It will mis-fire every couple of seconds and then after a while, one large mis-fire will knock the idle off wack and make the motor jump u...

Here we go again..!! I had this TURBO ka motor in my PREVIOUS S14 with the SAME IDENTICAL setup EXCEPT for the upgraded fuel system and new cams.. I never had ANY problems what so ever at all...!!!!! NO IDLE ISSUE's, NO stalling, NO mis-fire's.. And this was with an OPEN bov, IACV was hooked to the ...

Yes, i just purchased this S-afc II and the only reason i purchased it was for that dec-air control which will stop the stalling when i shift to N from any gear. But this afc II will not cure my other problem on why my motor starts to jump up and down when i cut OFF the ignition to have the turbo ti...

I have tried everything that everyone has told me and NOTHING works.
Im not spending another minute on this motor

I GIVE UP..!!!

Thanks to all

YES, exactly, I can boost at 14 psi all the way to 4th gear and i have no problems, i can sit there at idle and rev it to 3000-6000 rpm and hold it there with zero problems.
YET, once i get down to idle, it starts acting up. Frankly im gettin tired of this and ready to give up..!!

ARGH..... I cant open it...!!!

I COMPLETLY understand what u gurs are saying. Some ka motors have this problem, some dont. But what im trying to say is, when i had this SAME motor in my last S14, I did NOT have any of these problems at all !!!!!!!!!! I get this SAME motor into this new S14 i bought and now these problems occur. E...

..

On an AVERAGE ... an aftermarket (good street size) turbo should give about ~12 rwhp per pound of boost.. What other mods do u have OTHER than this Npsort kit...?? Im not sure if u guys know this, but that Npsort kit layed down 240 rwhp along with bolt-ons..!! Not just an OEM equipped plain ka motor...

Well, if he was putting 300+ rwhp on a stock bottom end daily driver and boosting that often ... i guess mine is fine cause i only drive mine on sat nights... Plus my motor has only 45k miles on it. I also used a rubber hose for my oil return that fmax gave me, i kept having to change it out every 2...

Ok, how do i do that..?? Is there a procedure..??

Thanks
Robert

Hey guys, whats going on. I just wanted to get a poll on how many of u r putting over 300 rwhp on stock bottom and is this ur daily driver or just a weekend racer..?? How long have u been pushing this much and have u had any problems yet..?? Reason why im asking is i just upgraded my fuel system for...

Please read below to my LONGER post reply to get more detail on my problems..!!

It begins with HERE WE GO AGAIN...

Thanks
