r33 gts25t with a to4e

just wondering is anyone else has had the same problem as me.

when im driving and have to stop quickly at a set of lights or an intersection the car nearly stalls and when driving up the hill then go to turn into my house it will stall unless i keep the revs up.

when i bought the car the guy said the blow off valve just needs to be tightened all the way and it will solve the problem. but iv done this and it didnt make a difference. a guy at a dyno tuning place told me that my intake pipe wasnt long enough but all my mates have said that that shouldnt matter.

my blow off valve is placed at the front right of the car just before where the pipe goes into the fmic. could this have anything to do with it as iv seen bov's placed just above the motor where the piping comes out.

can anyone help me please? some1 that has had the same problem would help?

Ive got a similar, if not the same problem....when youve stopped, does your idle go up and down? i just bought my car, and thats what mine does...its the aftermarket BOV...putting the standard one back on will solve mine, i just havent done it yet.

Definately clean out the AAC valve at back of engine near the fire wall- its easy to to do & theres a tutorial with pics here somewhere

Solved my problem-black carbon deposits build up in it-blast it out with a can of carby cleaner & some extra big cotton buds-takes about an hour to do

Mine occasionally does this, stock intake system. Everything's fine (spark plugs, ecu etc). Usually it happens when I am giving some steering input as well, I think the combination of dropping revs PLUS an emptying vacuum assist system is a bit quick for the ECU to keep up. For me it only happens when I come to a complete stop, the ECU maintains a higher idle point when the wheels are turning and only drops down to its base idle when you come to a complete stop.

I've talked to a couple of skyline lovers about this problem and they said it's could be one thing,

i strongly agree about some intake been short, of course you can make them longer and,

also put a couipe of bends into the intake.

What happens, when you change gears and because of your intake been short the

turbo blows air back through your intake and your AFM reads the air and the

computer dumps a lot of fuel into your engine but there is no air so you car stalls.

I hope you can understand what i mean.....And i don't your BOV is the issue....

Thats what i have been told.

ok thanks for your help will try extending the intake a bit and see what happens

That's bullshit, don't listen to that.

If that scenario were even true, it would only be true if you were dosing your engine. but you're not and the story is bullshit anyway.

Get a recirculating bov and move on.

making your intake longer is just stupid.

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
