Hi Guys,
I have a serious issue i suppose. My turbo while spooling is making a lot of sound. To be specific its making a high pitch whistle. I am not able to acquire speed. Anything more than 72 kph is making the sound louder.
I made some initial reading on this grounds and some say its a shaft play which I am not sure of. I am not over boosting it and everything is stock except for catback and pod filter.
Can somebody please advice me what could be the possible problem. I live in geelong victoria, anyone nearby that could lent me a helping hand would be very much appreciated.

Hi guys thanks heaps for your responses.
A very friendly SC member came in this morning to have a look at my car. He confirmed my bad luck to have a stuffed turbo . In mean time i noticed that when i got one of my friends to accelerate with the bonnet open, I got the smell of exhaust gases. Does this mean that I could have a blown turbo gasket on the exhaust side?. If this was the case then would it make the same noise as a stuffed turbo?.
Just a step ahead, does someone happen to have stock twin turbos for sale at all?.
Any sort of advice even in the form of constructive criticism will be very much appreciated.

Hi Everyone,
Thank you all for your kind co operation. I got couple of good deals on turbos but the problem now is where do I get them fitted?. I called a hand full of places and they all sounded to be rip off. Can someone out here kindly advice me a good place to get the turbo replaced around geelong and melbourne area?.
the second time i had my turbos done Ernest, i got it done at Dalton Automotive. If i remember correctly, the charge was 550 for labour, which i though was very reasonable.
MMM, dont think you would get much cheaper, it *can* be a shyte of a job to do. I have done plenty of things with my car, but for some reason always avoided the turbos. That said, have you considered doing it yourself? It doesnt take long at all to get the vehicle stripped down to bare turbos, and they you just have to fight with the stubborn bolts. Also remember its a good time to do the EBC if your up for it, just makes changing the Vac lines easier.
Are you 100% sure its the turbo Dean? I have popped IC hoses before and al off a sudden your making much louder turbo noise, no power etc?

It's not that difficult. I've done it twice on my wife's soarer (before converting it to single), once on my supra and about to do it again next weekend on my other soarer. Hardest part is wrestling with stubborn nuts/bolts. Make sure you have new gaskets and oil return hoses before starting. Also helps to soak all turbo related bolts overnight in WD40 before attacking it.

Hi Ross, thank you for the link. Unfortunately I dont have necessary tools nor a helping hand to do that. Although the process seems to be pretty straight forward as you said. How long does it generally take to remove and re-fit the turbos Ross?.
The tools are always available through people on here if you need them. Its just up to you, if you have the money and are happy to get someone else to do it, get it done at a shop.
How did you guys determine the turbos were gone?

Hi Michael,
I had a soarer central member to have a look at it one day. He had a similar problem in his car. Also, i took it to a mechanic and he told me taht its something with the turbo itself.

It's not that hard to remove the turbo's... That's the easy part. Getting them back on is the hard part.. It takes time and a lot of patience to make sure everything is lined up.. I've not long done mine and it looks like I may have to do them again as I have an oil leak.. didn't need many tools, a few spanners, sockets.. Nothing major from memory.

Hi Michael,
I am still in the process of replacing the turbo. I have ordered a set from one of the members out here. I also got walbro fuel pump, greddy profec b spec II, fcd and fmic installed soon as I get new turbos on it. Things are lying around in my garage for days now.

Werribee is nearby Michael. I should drop by someday to have a look at your beast. Im a beginner with soarer mods although I have owned it for over a year and a half.
At the moment I'm replacing the stock faulty turbos with stock working condition turbos. I did consider going steel wheeled c12A's and single turbo upgrade but it seemed expensive or complicated.

You're really better to do it once and do it properly. I see a set of high flow steelies listed here with only 50 ks on them quite cheap. They would outlast your car and give you plenty of upside for development if that's what you may want to do down the track. Either way still a better option I reckon.

Agree with Ross .
Shane had his High FLowed Steel Wheeled from Bill @ ATS in Adelaide .
After maybe 40,000km's they were sent away to be rebuilt again due to showing signs of wear .
I think people assume a Turbo should last a million km's ...
I reckon if you get over 40-50,000km's out of Any turbo , your doin pretty well .
After all, they are spinning over 100,000rpm and are going to wear out . Also comes down to Tune , Oil , Changes , Filtration , Quality of lines used ( wont cause starvation issues down the track ) .
I got nothing against going Steel Wheels and such , I personally think its the restrictive Manifolds that actually make people push them hard and wear them out quicker , but just dont expect them to live forever .

Thank you guys for the valuable information.
I am going a 3" complete exhaust system from dumps to mufflers to increase the flow and reduce the restriction. I know people are successful in raising the boost with steel wheeled turbos but then as Ross said there are exceptions.

New to the whole turbo game - the stock twins seem to be going okay at this stage, but I am unsure of how long they will last.. I know it's a game of luck and chance, as from what I have seen CT12's are hard to find on this forum.
