How do I quieten my stock blow off valve without putting my air box back in? I have a FMIC and the box doesn't fit anymore because of the cooler piping :D

I took my car to the licensing centre to get my yellow off but they said I have to quieten the bov somehow, and then they'll give me a permit for my cooler and my pod filter :confused:

I admit it's pretty loud, but it's totally stock!

What can I do!

Cheers :)

JiMiH my stocker bov was f'in loud when i had to get mine registered, they couldnt say a thing though because the compliance engineer had passed the air filter I had and therefore theres no possible way to shut the damn thing up!

I hate the sound of the standard one, its so bloody loud its not funny.

R33's must have the recirc pipe further down the line. I think the problem on the R32 occurs because the recirc pipe joins right before the air filter.

Just take the standard one off and bolt a plate over the hole, its not illegal NOT to have a bov now is it! Just get the yellow off and put the bov back on.

Cheers for the replies guys :)

That's a good idea about putting a plate over the whole thing i might just do that .... failing that I'll be up to your house Steve :)

I went to the Welshpool pits (they also didn't pass me because I have a chrome-look cup on my boost guage :) )

How do you put up with that shit?!!?

I admit, I haven`t been in Oz for quite a while, but that is just freekin crazy! On what grounds would they not pass you for chrome on a boost guage? Did I just type that...? *chrome on a boost guage*... yes I did...:confused:

The reason for pillar mounted guages being a problem is if they are within a certain radius of your head (can't remember number)and could be struck by it in an accident. Vision wise, as they are off to the side I don't believe they are a problem.

i have Blitz BOV on my car and i have it permitted as well as my Filter and FMIC. on my permit sayd BOV not to be too loud hahah thast the funniest shit i have ever heard coz it is loud as f@#k. I went to welshpool. They didnt pass my pillar guage coz yes was chrome and the light reflection was the only problem. I taped it up with tape and toook it back over (they passd it) its all a crock of BS if you ask me. My car handles and stops better than most cars out there yet i still get yellows for mods even if they are improvements. But what can you do. Cops should learn a little about cars and mods b4 they go out in the world and tell us what is and isnt wrong.

With little choice, its a police state here, ironically, they'll sticker a jap import for stupid reasons, yet a smokeing POS with bald tyres and rust throughout will drive on by and not get a second look

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
