Now what i mean by 'spirited driving' is not really from traffic light to traffic light. With a mate on a rolling start ive pushed it and braked to start on a roll, over and over again. Then there was a point where i realised that i was losing power, getting BOV Flutter as if i have no BOV, and NO pod filter intake sound at all! The weird thing is, i only get this issue for about a minute, then it goes back to normal where i gain the power back, hear the bov properly and also hear the intake sound. If this was the first time, i would of thought i heard wrong, but this is the 2nd time it happened. THe first time was after abit of spirited driving in the same style as well.

Ive got a HKS SSQV BOV, and im not sure if its real or fake cuz ive just bought it 2nd hand privately. Im thinking maybe it could be the BOV as i haven't had this issue before i put the HKS BOV on. But its been a long long while since ive put it on and i haven't noticed it so far till recently since i haven't really had much spirited driving or track since.

What are the possibilities for this happening?

- HKS SSQV BOV ( LEAK?)

- My Stock TURBO?

Need some help on this guys. Thanks alot for any input!

thanks for the replies. If i block the BOV off completely, wouldn't i still need to give it a bit of pushing to wait for it to occur again? Cuz its very random.

Im going to try put the stock one back on to see if it solves the issue. So everyone is just agreeing that it may very well be the BOV and can be nothing else such as the turbo? Cuz the pipes are all fine and connected. Should be no leak but then again, its a random thing so... I don't get iT?

are you still running the standard rubber air intake to the turbo? have heard of these sucking closed, would explain the loss of turbo spool sound and so on

standard rubber air intake? Sorry but wats that? Everythings basically standard except K&N pod filter, EBC, BOV in the engine bay area. SO im assuming i do have the standard rubber air intake.

If this could cause the issues ive described, could you please help me out in more sense to myself plz?

the intake pipe (between the air flow meter and the inlet of the turbo) is fairley soft on a r34 gtt. sometimes when the car is under full load on boost it can suck the intake pipe shut, kinda like if u put your hand around it and sqeezed it together.

Most people go about fixing that problem by cutting the intake pipe in the middle and putting a metal joiner in it, or buy a aftermarket silicon intake pipe from just jap etc.

oh serious!? thanks heaps barney for the help~ so i guess its not the BOV after all...

Ill go about replacing the intake pipe to an aftermarket silicon then.

Cheers

    • HELP   Hey all, Is there an accelerator cable from another Nissan that can be used on the R33 GTST RB25DET with a Greddy forward facing plenum?  Thanks in advance  Rob 
    • Or do we think it was installed to give 1 bar of boost max, all day, everyday?
    • So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit? 
    • Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
    • I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
