yer cause all i have is a pod filter and exhaust atm.

wanted to get rid of the bov and im about to fit the rest of my 3 inch exhaust system but now i require my licence for work im having 2nd thoughts

No, because you are pressurising the entire engine. I just remove the afm, plug the pipe and fill with compressed air to around 20-30psi. The closed exhaust valves usually hold the air back from my experience.

I tried this, only my plug was just after the turbo outlet. Air would leak out from the rocker covers or something, would hold bugger all pressure.

If there was a plug at the throttle body aswell as plugging all the hoses to the recirc valve and plenum, etc. Would the BOV still be closed shut and not leak, or because theres no pressure from the plenum being applied to the back of the recirc valve, it would be open slightly (like on idle?) and lose pressure?

Im sure theres a smarter way to explain what i mean but thats all i got lol.

ok so what about block the BOV up all together i really hate the noise to be honest ive lost my licence before and i now require my licence for work so last thing i want is attention from coppers with noise my car is stock thought has 3 inch exhaust and yer im abit worried about that aswell.

A stock BOV will make almost no noise ASSUMING you have the stock airbox fitted. It sounds like your real issue is a pod filter, etc.

However I will say that it can easily be heard operating with metal intake and pod, even during partial throttle and lifting slowly off the throttle.

I've noticed this with both my original stock rb25 and my current stock rb26 bov. I can hear it opening slightly at very light throttle loads audibly.

+1 to all he said.

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
