I have tried installing HKS BOV's onto my car. All together i have tried putting in 3 of them. Each of them stall my engine. Which means there is sumfin funny goin on wif my car. People say that my car is too modified to put one in but i think that is complete crap. I have got many mods, some people say that it is my Fuel/Air ratio is stuffed. Since the Stock BOV is a plumback and the HKS is an atmosphere BOV people tell me that there is not enough air goin back and the engine then puts in more fuel which stalls my engine. Does that make sense? Ive also heard that i can buy some sort of a Idle Restrictor from HKS that wont allow the RPM to drop and stall the engine. Ideas please.

Thankz

Chris

Your friends are correct. When the BOV vents your car will run very rich, so rich that it will stall.

Sell the BOV and stay with the stock one, if your really keen you can do the mod to it that is on this site (do a search).

Either that or buy a plumb back one.

There are little add on electrical things that can solve the stalling, plus a S-AFC will fix it too. But your money is best spent somewhere else.

nuh the think is i didnt buy it, First the guy installed it, then we went for a drive and it stalled, then he put in a second one, also stalled, Its not a tunning problem. He tried everything. So at the end i just put back the Stock one. So now my money is going towards a Apexi Boost Controller :)

I assume the vacuum hose was connected to the HKS BOV?

If it wasn't that would make it still for sure...

Even the stock BOV will stall the car if its not plumbed back! I tested the stock one vented in my car, return pipe blocked, Bov vented, vacuum hose connected = drives for a while ok, then HALT!!! Nothing :D

yea it was all connected correctly. The stupid thing was that the person who had the car before me was driving it with a HKS BOV. How dangerious is that if you are on a round about when u have to go slow and your engine goes off. Brakes and power steering are gone. Dont know how he was driving it. Plus it wrecks the Clutch 100 times quicker. I staying with the Stock BOV and saving up for a APEXi Power FC. Damn i wish i had a money tree :)

i have the same problem with mine i got HKS ssqv. skylines seem to have alot of problems with BOVs the vent to much pressure out causing the car to stall.

the only BOV that i have been told that does the trick and doesnt stall are turbosmart ones, but my friend has blitz one and is does it very rarely.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
