ok so i got my hands on a GTR BOV and a bigger hose for the plumb back and connected it all back up just like the stock GTT one was.

all is well but when i come on boost say around 0.5bar maybe more (highflow turbo set to 1 bar) while still in gear and and let of the accelerator the car makes the normal psssh sound but it also makes a (very hard to describe) different noise also. kinda like a viberation noise but not quite.

ill see if i can get a recording of it.

but has anyone else experienced anything different with a GTR BOV?

im not having any other problem. car is holding boost fine. idleing fine. just the noise. and the strange noise is pretty loud too if your outside or have the window down.

help.

i get the same bloody noise. if i boot it, no noise. if im barely making boost no noise. its during normal accelleration that it makes it. a kinda honking vibration

when's the next meet? i'll show you if you rock up. remind me or some shiz

around 6seconds into the vid, does it sound like that? If i get it onto boost abit and then half throttle, it will do that sound. A mate thinks it sounds like a poo going down the pipes LOL

thats the sound hahahaha

thats it. like taking a bog with your ass sealed and you get that deap noise lol

any idea what it is??? if its anything bad? at first i though it was just the stiffer springs not opening enough. if i accelerate hard, change gears and accelerate again its fine. only whne slowly getting of boost it makes the noise.

hey not exactly on topic here but...along the lines i guess.

ive got a gtr blow off valve and i removed my standard r34 gtt one to replace with gtr, now when i pushed the valve up into the gtt one it is very stiff and hard but when i push the gtr one (with my fingers fron the sealed side) it feels softer...has anyone experienced this with there blow fof valve as i dont want to put the gtr one on and go for a tune with it if its stuffed ya know!

hey ash,

long time no speak... i changed my gtst bov to a gtr one and also got that exact same issue! but i got rid of it..

i dont know if its the same for u, but the pipe i got to suit wasn't exactly perfect and I had a guess that the sound was of some air in the pipe as it was expanding or contracting... anyway, got a hose joiner to try to keep it more solid, and worked fine, not an issue any more!

can send u some pics if u want :ermm:

i thought that was normal? i swear there are some threads around about that and it turned out fine... my gtr bov is alot softer then my gtst one, but it does the job better so I assume its fine...

O great, another thread with somebody being worried about how their blow off valve sounds :(

oh wow thanks for your input...

vidospace the advantage with a GTR BOV is it holds more boost. only worth it if your running more boost then stock really as its a plumb back so its nice and legal.

alright, took some shots.

not the prettiest thing in the world, but she works well. definitely alleviated a lot of tension across the pipe.

im pretty sure it was a radiator hose bleeder or something, because I had to buy that gold blocking screw. was like 30 bucks all up and works fine.

P.S u can leave the screw out and it gives it a lil bit more of a whistle, but im not into that sorta thing :banana:

I slapped a GTR bov on my car after I got rid of the megasonic ears bleed loud wank bov. I then got stickered to made it plumb back. It made that fats noise. Like air was blowing past the rubber pipe making in vibrate sounding like a fart. Another of my friends gets that too. Wonder why that happens. It atmo again as I got the sticker off. so meh

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.

      Looking for someone with a R34 front bar

      Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂

      new 1.5 LSD issues/concerns

      Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
