Spraying the turbo with WD40 will do nothing to help the situation.

Here is a potential cause.

Having a series 2 your turbo has a bakerlight compressor wheel, a very hard plastic and this could be scuffing on the housing making a squeek or high pitch squeel.

It happens because the shaft wears out and usually there is forward/backward movement in the shaft causing it to push forward on the housing or backward on the backing plate.

It will eventually explode and throw bits of plastic all through your intake soon if the noise is in fact coming from the turbo.

Or you could have a bird in there that is opposed to greater boost pressures.

Kind of like a Nissan Nazi Budgie.

If anybody watched Top Gear on Monday night and saw the actor who drove the well priced car around the circuit and Clarkeson asking about a string of 911 Porches he had owned. As they were chatting about his string of cars he admitted he new bugger all about them and on one occasion was driving his brand new 944 he had picked up the day before, realising he didn't like it he stopped off at the Porche dealership and got another 911. He couldn't tell Clarkeson what model it was and the only one he could remember was the one he was actually driving to the interview. He couldn't even tell if any of them had been a turbo or RS or wide body.

My point ? If someone knows nothing about a particular car and still can't find the time to read enough to at least make some kind of considered opinion as to how it operates then does he deserve ownership ? Of course he does. That's what money is for. I wonder though why there are no longer any genuine GT Falcons left. GTR XU1's ? E49 chargers ? Because they, (like our Skylines will eventually be) were thrashed, crashed and neglected by people who never took five minute's to learn even the basics of maintainance before asking how their engine blew up. But hey, stuff it, it's just a bloody car after all. I shall now don my fire suit. Let the flaming begin.

Some funny replies there. My problem is, i bought a turbo off someone from the forums, put it on my car a few months back cause mine was f*ked and while changing it the gasket was kind of breaking but i had no way of getting another one because it was a public holiday.

So i used the original gasket. On sunday i had an exhaust leak which sounds like its coming from the gasket between the turbo and manifold. I bought the new gasket today and since half my stuff is out i thought i would spray wd40 in there to possibly help the squeak.

I wanted to know if it would hurt the turbo NOT fix it.

Oh and whats a flange?

the base of your turbine housing bolts the the FLANGE on your manifold. your manifold starts off with a flange, the item that mates agaisnt your head....

if metal flanges remind you of pussy, you are getting some bad pussy.... real bad

I sprayed about 0.00007 cents into it. Just the fro nt wheel, then wiped the remains away when it went to the bottom. Meh, im more annoyed that one of the studs came out of the manifold.

To save me the run around and because i need my car for work asap due to my boss not wanting to pick me up everyday, where can i get a new stud and nut?

Cheers

    • Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!
    • Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.
    • Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg
