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!

any help would be much appreciated.

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

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
