Blitz Bov.... Tried for three months to get an adaptor plate to fit where the stock one was.... NO GOOD. No one had or could get one. So i had to get my mechanic to Fabricate it on to the pipe leading to the Throttle body. (under the pod). It cost a bit to do it, but it sound's great and looks nice.

I'd show a photo, but i dont have a digital camera.

Cheers

Well, thought i might of had some boost loss (i got worried when people spoke of "boost leak") But after some under bonnet testing (rev hard and watch valve) i noticed the "button" (copper release thingy) moved down furhter on rev..to seal the BOV . So i took it out for a hammer (foot to the floor) and it all seems fine.!!

Next is the Boost Guage.

and maybe the "Skyline" logo lit up in Blue....

I haven’t been able to find a adaptor for the Blitz my self do they actually make them?

I think I'll go for a GFB or Turbosmart pop off valve:)

I used a Trust Type R BOV on my GTST. The BOV kit itself doesnt inlcude the adapter however Advan at Silverwater sell the adpater plates for GTS-T so they bolt straight on.

After using a Turbosmart and an HKS SSQV BOV I found the Trust to be a better unit and experienced less idle/stall problems.

holy cow lozza...im not sure if all those series of blitz bovs are the same or not...i've got the same one..and from the look of ur pic..ur one is really really loose...are you sure its not leaking at idle?

unless ur screw has been changed....cause my one you can see about 3 threads after the nut which is about just right...

do u have probs with rev's when coming to a stop after hard run?

The Mechanic's adjusted it to suit with the standard BOV unit connected as well. After disconnected the stock one and now just running the Blitz one... It's a lot louder.... but "seems" ok. After a good run, it does drop the rev's very low...for a split second, then it must seal and all is ok. It's hard to tell if the unit is not leaking... Logic tells me if it was leaking, I'd lose boost pressure on the guage... but it still show's the same ..7PSI... (yes stock i know..) So i guess I'm not.

As posted earlier doing a rough run in in the garage showed the brass thingy to push down further during boost pressure....(vacume change i guess)

Eventually when i get an exhaust and stuff fitted ill get a dyno tune, and they can check all that for me...

ive had three blow of valves in my s15 since i bought it blitz super sonic s1, then a apexi dual chamber and how a blitz super sonic s2 i found that even though the s1 blitz was 2nd hand from japan of a s13 silvia their was no idleing probs or boost leak and had and awsome bark goes to show theirs nothing like japanese engineering!!! i have a friend who had a brand new gfb bov installed in his skyline it shit itself after bought 13000k's the piston jus kept seizin?//// then swapped my blitz s1 for the apexi dual chamber it was good but didnt really find its sound loud enough(riceboy) and it was a big& bulky mfuca in my engine bay, now i have a blitz s2 its awsome has a diff sound to s1 not as loud but fluters a high boost cause of the fluted design of the outlet. i can give u a contact of some one that can get u a genuine blitz mounting adapter for skylines for bout 30-40 bucks but his in sydney? and its 2nd hand?

    • 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).
