Hi there,

I have to get a new turbo for my GTSt as the old (stock) one died a sudden death. The guys doing the job have been ringing around to see what will fit my car with minimum fuss. (bearing one - not ceramic).

I know (from reading other posts mainly) that there are quite a few different turbos that people use but everyone the performance guy's spoke to said nothing will just bolt on but you will have to do ALOT of plumbing. (and hence make the job more and more expensive.) I want to get some change out of $3000 for the job.

Is this true? Is there anything that will just bolt on (or not require hours and hours of extra plumbing work)

Thanks

Guy

Hi Lachlan,

To cut a very long story short, my car dealer missdiagnosed an oil leak from the turbo area of car. Nothing to worry about I was told. Fix at next service. Said a oil pipe must have gone brittle. They do that with the heat etc...

I ordered a Microtech ECU and decided to get everything tuned, services etc when the computer came in. This however took about four months.

When the service guy took the housing of the Turbo to fix leak, he discovered that the seal was rooted and there was a HEAP of 'play' in there. (I could presssomething in and out that I shouldn't have been able to)

He even refuses to drive the car in his workshop as he is scared the turbo will break/seize (whatever they do when wrecked !)

I had the boost set on standard. I do not drive hard at all. I have never raced my car. However I now believe the previous owner did.

It used to have a HKS EVC with boost set to 12psi. I am now selling that. It has a huge intercooler now. Fuel cut off defender ??? POD, and I think a heap of other stuff. The mechanic said 'My car should be sponcered by HKS !!'

I am really annoyed at the moment as I have to pay for a new turbo just four months after I bought the car. Even though the thing was on the way out when I bought the car !

Sorry for this rant, but I am left with a sick feeling in my stomach over all this... I don't know who to blame - me for not knowing anything about these cars when I bought it or the car dealer seeing me coming !

Thanks

Guy

The problem is that most ceramic turbos are "on their way out"

Think about the car being around 7 years old, and most people don't buy a performance car to drive around slowly in.

Most if not all import performance cars have been thrashed in their lives!

Thats just part and parcel of buying an import.

Perhaps if you wanted to drive a car slowly then a holden would of been more suited to your needs :P

Hi flow, is when they take off the turbine and compressor covers and bore them out, allowing bigger (steel) wheels to be placed in there.

If you dont have alot of money to spend, you could buy a good second hand turbo for $400-$700 and put that on. If you want to high flow your old one when you have the money, and sell the 2nd hand one that you put on in the mean time to recoupe the money you spent.

Just some ideas

High flow involves:

Turbine Wheel - replaced and upgraded with a inconel(steel) wheel , either stage 1 or 2

Compressor Wheel - replaced and upgraded with T04 wheel, either stage 1 or 2

Bearing Pack - replace with an XTR ball bearing package

Turbine Housing - machine to accept either of the larger wheels

Compressor Housing - machined to accept either of the larger hi flow wheels

Wastegate Actuator - standard or upgradeable to have higher boost pressure as standard

Actually DREMEN, I never thought about it that way ! I don't drive slowely - I just don't race the car at the strip. When computer, "TURBO" etc are done though I will see what I can do the 1/4 in though...

I want to see how I go against some of the hot Starlets/GTiR's/etc that are around Toowoomba !!

Anyway , thanks again for help people...

Freebaggin,

No it's not stuffed. Actually what happend was I had an alarm fitted, and the when I got the car back all the boost settings were gone and it was a real pain to reset everything. Real pain.

A mate offered me $500 for it (an old BMW he has done up - 12 seconds !!) and the guy at the performance centre said that I didn't need it when the Microtech was fitted so I took the cash.

Aparently I can bet a much better one for $800 if I realy wanted one. (not sure what brand though - Autospeed.com have been advertising them lately)

The guy at the performacnce centre actually chose a turbo this arvo. I will get the specs tommow. I know it is rated to 500hp and can easily be boosted to 20lb. it is $2300 + fitting (approx $400) - (I just have to sell my TV/stereo/video camera first - lol, so I can afford it.)

He said later on I can then up the injectors and do something simple to the turbo (I forget what he said) and "It will really get crackin" He mentioned 300HP at the wheels !!

gjb977 just remember the stock engine internals wont like running at anything above 16-17psi for long/hard periods, the injectors will need replacing to keep up with the flow plus you'll need an aftermarket ecu to make the most of it all without a little bit of careful thought you could end up doing more damage then good. Do searches on these forums, you'll find a lot of information on them for pretty good sources in regards to what you can and cant do on the stock internal engine.

    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
