My 32 has twin blitz blow off valves, which are perhaps a lot more audible than I would like.. see, Adelaide is known as the defect state.. and I can't afford to refit the entire car back to standard if I get caught.

Q) how loud (if any noise) are the standard gtr blow off valves? considering I have twin pod filters.. it sounds pedantic, but the nazi cops love seeing imports to fill their duty quotas.. and if they hear any light 'swooof' they'll slap a sticker on my car for a full inspection. As unfortunately is the way here; your guilty till proven innocent. :)

If you want, check out the outstanding ‘regency experiences’ thread by Steve in the Adelaide section to see what we face.

The stock BOV's do make a fairly audible "chooooof" noise when fitted with pods. They are however perfectly legal as they do plumb back to the inlet. If the cop is being an ass, just try and confuse him by saying ltos of big words like "the pressure release valves are perfectly legal, they are recirculating back into the intake of the engine" etc. Most of the time (in ACT at least) they give you the benefit of the doubt.

Cheers,

Though if I fit the standard blow off valves back on (as my car is WAY too loud now) I've heard about issue's with them leaking. I'm currently running 1bar, and would like at some stage to run a tad more.. can you effectly prevent them from leaking when raising boost or even running what I am now?

Generally you will be fine unless you make a point of "venting" within hearing distance of a police officer/car.

Luckily, aftermarket bovs on a GTR are not visible in the engine bay, assuming of course that you have your aftermarket bovs fitted in the factory location.

Police normally have a go at you for what they can see. Out of site out of mind.

Theres cars making in excess of 500kw using the standard blow off valves, they are really good. However, you can occasionally get a dud one which does leak...

    • 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!
