I have a hks 2530 turbo on my r33.

Recently i have started hearing a whining noise very very similar to the stereo whining noise you get when you dont earth your sound system properly.

It sounds like its coming from the cabin very close to the centre console and passenger airbag area.

The noise only comes when you are above 0 on boost (apexi boost gauge). It still hits full boost (1 bar) and holds the boost there so no loss in power.

I tried switching off the headunit to see if it was stereo noise but no. noise still there.

I even tried switching off a/c and fan to see if it was that electrical circuit affecting it but nope.

Please help.. im so stuck and the noise is not very loud at all but its annoying. :confused:

Cheers

Michael

I had that, check to see if your GF is sitting in the passenger seat? :P

Seriously though, I've got a turbo whine sound that seems to be channelled down the left wing into the cabin, by the passenger kick-panel...with the panel off it's VERY loud.

nar checked already....gf was in the boot...

i recently had my bov plumbed back but i dont think that could be the cause but could it?....

Its a blitz bov, had it plumbed back...it looks shit coz it doesnt seem to every close completely therefore boost leaking...maybe thats the problem.

LMAO, ive got the same problm with my car, but my turbs is stock. A friend of mine, who is also a mechanic told me its leaking. Hopefully urs is just a simple inexpensive fix.

May i ask what power your making with what mods with your 2530. Im thinking of going one of these, but am very unsure.

cheers

Basically, when I had the plumb back adapter for the BOV made from the mechanic, they reused the original gasket, after a few days it started to leak, so i went to supercheap auto, bought some gasket paper and cut it out to the same shape as the original gasket. Fixed the problem straight away. No more noises.

Make sure all your intake pipes are secure and tight, you might be leaking from any of the joins.

Good lcuk

Regards

      Slight brake pedal stutter after new pads

      By PranK · Posted

      Hey keep the ideas coming, I'm always keen on projects! But, problem fixed!  I got a cheapie ozito scope from Bunnings and had a good look in and around the bearing and sensor hole. I couldn't see a smoking gun but the bearing looked a bit strange, especially when comparing with a new one. I thought the cover had come off the bearing magnets.  Sorry for pics of a screen, I didn't have an SD card.     Good thing I had the old one to inspect. So, given I'm like a pit crew with wheel bearings and luckily I had a spare bearing because I f**ked up my parts order, I decided to just smash it out. Got the old one out in about an hour. So much easier when the parts haven't had a chance to rust together yet. 😂 And, well, found the problem.    In the second pic at about the 8 o'clock position, you'll see what I think is the tip of the old sensor.  The new sensor has definitely been rubbing but it's all intact, just a little shiny so I'm hoping it's fine.  The car brakes perfectly now and no errors.  I think the job took about 2.5h in the end. 👍🏻 I really appreciate the help in here as usual. Thanks guys.

      I was only looking because I saw some drops on the ground but it wasn't alot. Recently had it serviced will ask the mech to confirm. Find it strange that it looks standard though, can see in another photo of a random box

      So...not sure if you know if that has always been there or why you went looking. It could be old damage from a clutch explosion, or even just the gearbox got dropped somewhere along the line. Basically, you should seal it up to stop oil and dust getting into the bellhousing, but it doesn't matter too much and is not structural. I'd suggest something like a glob of JB Weld. BTW what gearbox oil are you running, I would guess the breather has been spewing it everywhere.

      Hey Duncan thanks for your reply. Sorry mate I know the photos are shit.  Took another photo for reference. Seems the casing does have a hole in it looking on the net, fluid seeping out. Added a photo

      Very hard to make out what you mean, is it the squarish hole with redline shockproof (probably) under it? Is that pic from on top of the engine with the firewall to the left of pic and engine to the right? Either way, spray the area liberally with degreaser and try again, maybe circle the part you are worried about
