I must admit that when I first read through this thread I drew conclusions from the text, but didn't listen to Chris's audio recording. At Billy's insistence I listened today and it's EXACTLY the noise I get, so I'm 99% sure it's the BOV.

So my options are either to buy a new one (Nissan or aftermarket), swap with someone and test, or block off and test. I hear aluminum cans work a treat :thumbsup:

I just rang Turbosmart to get the low-down on what the most suitable BOV is for the M35.

The Kompact Plumb Back - Nissan (TS-0203-1226) is suitable for the stock ceramic turbo and for a GCG Highflow PROVIDING you don't turn up the boost. So that is pretty much a no go for those who wish to dial up the power output in regards to PSI.

The best option for a higher PSI is the Nissan Dual Port (TS-0205-1026), as mentioned earlier you cannot run the trumpet due to the restricted space, it is recommended you don't have the trumpet on and block the outlet (Turbosmart have a Port Blanking Plug that does the job). The unit would have to operate as 100% Plumb Back (which was what I'm after anyway).

I've just had a quick look on the net and the pricing is around $460.00 for the Nissan Dual Port.

If anyone can offer any feedback on the Nissan Dual Port please do :)

Aaron and Scotty, this is what I was on about on Saturday night. This is what I was told by both Turbosmart and MTQ. I know you keep saying that I can run the Kompact with the softer spring Aaron, but I don't get why they keep saying the Kompact is only for lower boost applications?

Both say they're suitable for Stageas, Kompact runs $153 plus shipping, Dual Port is $310 plus shipping. Neither will exactly break the bank but I'm guessing they're cheaper/easier than a new factory Nissan BOV.

As far as I can tell, Turbosmart are the easiest to get plumb back BOVs. I know there are Blitz, Greddy, etc, but they don't seem to do plumb backs.

did you see the price he was quoted for a dual port?

thats why we arent allowed to use the cheaper one. just replace cant run high enough boost with we cant get a higher pay.

honestly i ran the kompact series for ages with no worries at all. soft spring is fine and that was at 20psi.if our stock ones are handling it with just a plate and shaft design, im sure a piston design that the kompact has will outdo the job fine

Yep. Have for a while. Just trying to work out how best to fix it.

Aaron keeps trying to save me money :whistling:

do you really want something that sticks out like dogs balls, as compared to something almost unoticable..

the later kompact series are completely adjustable aswell.

Agree, but how it works is more important.

Fine, I'll just order the Kompact with the soft spring. Should fix the issue (I hope).

well check the issue is the BOV first with swapping with someone else for a run.

then get it.i wouldve given you mine had i known.. it just needs a softer spring. i had a stronger spring so I could Vent to atmosphere.. then i grew up lol

Nah busy tonight, might aim for a weekend. Or if I can get one locally at the ~$150 I'm looking at for a new one on ebay, I'll just get one. Not worth continually stuffing around.

No dramas. Id give JDMSpares on ebay an email and see if theyve got one - they have some other odd parts for the M35. Located at Lonsdale unfortuantely. Nisswreck also have an M35, but I think they wanted to do a halfcut so they probs wouldnt be willing to rip the BOV off :(

:rofl: yeah I suspect theyd be easier to work with in person.. You dont get it from their website, but its a pretty damn big wreckers yard they're running.

I suspect they were probs wanted to try and offload a BOV not directly off the M35 they have whole - ie something off a shelf; which is why they wanted the photo. Also, the girl that answers the emails isnt necessarily a cars person (She might be, nfi tbh)

Pretty sure they dicked me around last time I looked for parts.

How much is a standard BOV worth though? I'm not prepared to pay $100 for a second hand one when I can pay $150 for a new one, and know I won't have an issue.

Anyone know the going rate?

Has anyone actually figured out if this is a BOV problem?

I still have the exact same issue, and Im confident its something to do with the wastegate as you can hear it reverberate right through the exhaust. It literally sounds like its underneath you when driving. If you hold the throttle right when it happens you can make it fart as long as you want. I tried blocking my BOV and still had farts.

To me it sounds like the wastegate isn't opening properly or shuddering. It only farts under medium load. If i floor it it cannot fart - its like it opens properly then, but if im building boost up a hill slowly it happens most of the time....

Surely if it was BOV it would still fart when I floor it. It would fart at the same boost level everytime?

I want to fix this as it shits me!

    • 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).
