Hi, my car is a S1 R33 GTS25t and the BOV in question is a Blizt DD. After intalling the BOV when breaking into a shape corners the engine will stave of air and stall on me. I have try this a number of times and it still stall on me BTW the car is AUTO. I think it's the hose overheating or the ECU is not use to the BOV yet. I have reset the ecu and will test some more on the weekend. did anyone have any problem like this before? maybe because i'm not running a pod.

Also can anyone please attach a pic of the engine bay with apexi pod installed with stock AFM.

Thanks in advance.

atmo bov you have. atmo bov no worky. it vents air, the engine expects that air is still be there so it adds fuel / timing to suit however the air is not present so it runs too rich and stalls. fix use stock bov

dude, you can't fix it.

Well, actually you can. Either plumb back your BOV or put the stock one on.

Why would you bother putting a loud fully sik OMG!!!!111oneoneone!!!11 BOV on a auto anyway.

Do you drive around, foot flat, and taking it off the throttle quickly to make your BOV vent on purpose when there are some fully sic chiks around?

Let me guess, you're a poser?

hhmmm

atmo bov you have. atmo bov no worky. it vents air, the engine expects that air is still be there so it adds fuel / timing to suit however the air is not present so it runs too rich and stalls. fix use stock bov

This is why your Fully sic BOV is making your car stall. You run an AFM before the BOV, it measures air that is gonig into the motor and the ECU puts fuel and timing in to suit.. Use a Vent to ATMO BOV and it takes away this air and leaves the fuel behind..

And what do you know.. that fuel doesn't have that air anymore to burn, so it stalls, pops, farts, and carries on.

If you want to run a fully sic ATMO bov, get a powerfc d-jetro and run a MAF at the throttle body.

That'll make the chicks look....

oh and if your wondering why your getting a lot of smart assed answers...Next time, try using the SEARCH function, this topic has been covered about 34568938930295345 times, by people that have no idea about the car they drive. They think you just turn the key and the wheels go magically. And they also seem to think that if you install a Vent to atmo BOV all the chicks will line up and want to ride with you.

lol can't believe I typed all of that.

why does everyone say use the stock? If he wants the sound, he is entitled to it.

It's all about the setting of the BOV. I got a Greddy Type-S and my car doesn't stall at all! It's all about adjustment, tighten the spring and it should stop stalling, but don't tighten too tight otherwise it'll flutter and the BOV isn't actually doing its job.

The only side effect of an atmo BOV is that it'll be rich when the BOV vents, and you may get a bit of backfire, especially after letting off on hard throttle.. but being an auto, you won't get rich conditions on gear changes.

having said that, yeah, he should get flamed for not searching.

Any Tech feed back? thx

you got it within the first 8 words of the first reply

atmo bov you have. atmo bov no worky.

simply put, you wanna use an ATMO BOV... you'll need to purchase a SAF-c/PowerFC and have the thing tuned so that it wont spit the dummy

This can be found by searching and reading, trust me :blink:

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).

      Jacks that fit under GTR lips that can reach the subframe?

      Perhaps the answer is... more jacks!* *proper jacks must be used.

      I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
