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

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛

      Nah, not really responsible for that little fiasco, but I'm still pissed at myself for writing off my 86, or when I reversed my VX into a pole just before selling it, but, meh, 5hit happens to stuff, all it takes is a slight distraction, and life is full of distractions, and "dooh" moments
