Well yea nothing wrong with the logic. You may not realise that your idle control valve does exactly this.. opens at idle. Similarly on some cars (supra that I know of) the idle control valve has its own filter.

Re youtube: I can't fathom why that BOV would be open on a car that is making positive pressure though, that is just boost leak. Unless it was purely for demonstration.. but a pretty retarded demonstration if he then shows the boost leak continues under load :S.

if you actually remove the plumback pipe from the std rb25 bov, it is actually open at idle just like this setup.

if you infact watch this other video, it works.

the whole point of it being open is to allow more free flowing air into the engine before boost. if you think about it as he shows you, the turbo adds an air flow "restriction" when the car is off boost thus downgrading your throttle response.

NOTE: it would only work if you have a plumback setup for the air being released from the bov to pass back through the AFM, or either plumback or non-plumback for MAP sensor ecu's.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
