I was told that atmo BOVs were illegal now and a fix for it was to filter output gases, well I looked around and K&N had one about right size but I had to modify it a bit to fit and the wire I used to hold it it on is a temp until I find something better but it stays there and thats all that matters ATM

Atmo bovs are illegal on the Skylines as they run a closed system from factory.

If you vent this air out fuel will dump in as the ecu still thinks the air is in the system.

The only way to make it legal is to have it tuned and emission tested.

If the car was released without an AFM then an Atmo bov would be legal, providing it was filtered so it doesn't spray oil vapour everywhere.

It isnt really the gas vented from the BOV itself, but moreso the effect it has on the engine fuel mixtures that causes the emissions concerns and problems.

In the real world we all know high performance/modified cars aren't going to effect the global warming and pollution problems in any significant way whatsoever.

The fact still remains, unless its a plumb-back its not legal by the authority's standards.

Hell they could defect you if it was a plumbback even and it wasn't OEM fitted.

To think the filter is going to do anything at all is wishful thinking, it won't help emmisions and it won't fool the coppers either. But if it does the few $ spent on the filter will be worth it.

Cheers.

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
