Drivebai,

I reckon just use the factory BOV and plug the intake pipe recirculation hose and leave it to vent to atmo.

The S-afc has a setting called 'Dec-acel' the manual contains some settings to use for the RB25DET, I don't have it to hand atm. HAve a look in the manual. If this setting is disabled the Throttle % will be 0%.

46n2,

Yes its normal, the 32's with standard bovs are very loud. Ive now got one that vents to atmosphere and is quieter. Theres nothing wrong with the operation of the standard bov, its just that it vents back right before the air filter and is just as loud, if not louder, than an aftermarket one. Seems to be very sensitive to throttle too, where as aftermarket ones tend only to vent LOUDLY when you WANT it to, not all the time.

I was asked by the cops to change my BOV back to factory when it was already factory. They couldnt believe how loud it was.

I put the plumb back hoses on again and tried blocking the hole under the BOV to see what it does in real life.

I actually like the effect it has, except it certainly doesn't make the car quicker (for those who thrive on placebo effects). It does give a better response when the throttle pushes the vacume into a range just before '0'.

That's pretty much the same result I had. It sort of feels snappier (very technical term !!) around the 0 to on boost part.

But the thing I like the most is it's quieter than before :D I don't get the sound of air recirculating as much now. The HKS filter does enough of that (which I'm thinking of swapping it for the standard box sooner or later)......

      People still have Skylines? I thought they're non-existent now.

      Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.

      They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.

      I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
