What does a dieing turbo sound like?

Turbine wheel missing some chunks = severe imbalance about to occur if you keep running it. You have a spoonless grenade with the pin pulled in your hand right now. No idea when it's gonna go BOOM. It's definitely on it's way out. Also, the more you run it, in it's current condition, the more fine metal particles will grind their way off the compressor wheel and be blown through your intercooler directly into your motor. If you're lucky, the intercooler might catch most of the pieces, but it's the fine particles pieces that will eventually make their way straight to your bearings in the motor. I've seen more spun bearings in motors caused by this over the years than blown head gaskets.

I would advise not running it further. Also, if you still have the factory oil cooler in the stock radiator I would discontinue using it by either removing the sandwich adapter and plugging the lines, or install a new oil cooler in place of the radiators cooler. And flush that intercooler thoroughly before running it again. Unfortunately we have nothing used for sale.
Hope this helps.

Ya...I knew you'd say that:D
I'm not actually stupid....but I really like asking stupid questions.:p
Papa Lou promoted me to half stupid awhile back.:biggrin:

I no longer run the factory oil cooler. I switched to an F-body radiator awhile back and only run synthetic oil.

I looked at the compressor side again and there is no actual contact on the compressor side between the blades and housing...but it's definitely close when I checked the play.

Can you PM me a quote on the turbo you suggested?

I'm weighing options.
I have a line on a good journal bearing GT6152 with about 1000 miles on it from one of the local guys, but definitely would prefer to go with something new and better.

Thanks, Patrick.
 
Kinda hard to get a good shot with the downpipe still there, but...here's an idea of what the blades look like...
You can see the blade to the left is a tad on the short side...its the worst one, but a couple others have pices missing too.

I drove about 1.5 miles with it like this and kept it out of boost.

I'll pull the bugger and get some better shots.

Tick Tick Tick Tick Tick Tick........

Ouch, I feel your pain there.
You might be able to drive it easy for a bit, but I would definitely be skeerd myself.
I will send you a PM about our pricing on those units.

The Air Cooled Dual Ball Bearing version would probably spool up really fast and work great if he kept the boost below 26 psi range. With cam and head work I'd really like to see the 65 turbine wheel on it to keep the back pressure at bay. But, if he wanted more of a tire fryer that it already is, a ACBB 6262 would scream on that setup. Pricing is the same on both styles.

I hear ya.
I only dorve it from the time I first heard the wierd new noise until I got it home (1.5 miles). It's been parked since and won't move until a new turbo is on there.
Lou would kick my balls if I drove it as is.

I don't want to be traction impared by useless power on the street, so I'll pass on the 6262 unless there's a screaming good deal on a nice one and I'd just keep the boost conservative.;)
 
I'll be handing the cash to my beautiful wife so she can go buy something pretty since I got to buy something pretty....:rolleyes:

I kinda love her and want to keep her around...so it's just smart to keep the peace.

Chicken, just hang it up on the wall. Give her the line and a stern look maybe a tear or two if you can muster it "Its just something I HAVE to do" kiss her on the cheek, and continue to build your mural! She'll let you be!
 
you better get a 66 tim you wont be happy spending money on anything bigger or small imho knowing your driving style the 66 is perfecto el polo

She's way to smart to fall for that crap:redface:

The T66 I saw was an e-bay special...I've ruled that out at this point.

I'm gonna do it right this time. Something totally new tech.

I know a couple guys running the 6562...one with nearly the same combo as me....and they're pretty slap happy with them.
 
the one dude was right....a 6152 is a very nice street turbo i just took mine off and replaced it with a 6765E which is stock appearing what you want.....and let me tell you....if u have the goodies in your car like you do to go along with a 6765E. That turbo is a MONSTER!!!!! And i love it! Not to mention its a 900HP Turbo :eek:

Yah, that "T-66" is the one GN1 performance sells and is all over fleabay....don't waste your time with that china-made junk, get a good name brand unit and be done....The way you race around on a daily basis, Ball Bearings would be your friend :biggrin:
 
I've got the 6562 that Patrick prescribed on my Christmas list.:biggrin:

As soon as I get the house carpeting and property taxes out of the way....I'm calling Patrick.
 
I would be figuring out what ate the turbine wheel. Spark plug ground strap, valve guide, etc? I have wasted turbos before, eating up a turbine wheel means something went through it.

I'm pretty sure it was repeated horse sneezes at WOT and 21 lbs of boost that did it. I drive this GN every day and it see's WOT blast or two....or five... every day....and I rarely if ever let off the peddle slow. Over time that prolly created too much play in the shaft on this 8 year old turbo and the fins of the turbine wheel prolly made contact with the housing.

Also the death occurred right as I did a big horse sneeze at a Mustang.
The engine otherwise ran normal after the turbo started sounding funny, so unless I had some gasket material go through it....it was all the WOT horse sneezing I've been doing over the last couple years.

I'll be pulling the exhaust manifolds to have them welded up and inspecting the spark plugs too, so we'll see if there are any remaining unsolved mysteries.
 
Pulled the turbo tonight.
Turbine carnage is not as bad as I thought. Only one turbine fin got damaged on the exhaust side. In the 2nd pic, you can see where it dug into the housing....two little bright spots right where the broken blade is. There's also witness marks around the radius.

On the compressor side, all blades are in tact, but the upper side of the housing did get kissed by the compressor wheel. You can see the witness marks, but can't really feel it when running a finger tip across it, so I think I'm OK in terms of stuff in the IC, etc.

FWIW, that is a TA60, not a TA61.

Nuh uh...
It's a John Craig (Precision) built TA61 that was built for my buddy Spoolfool2 about 8 years ago.

It made countless low 11 second passes (as good as 11.17) on his spotless GN before he traded up to a water cooled 6265 DBB.

I bought it from Spoolfool2 a couple years back for a nice fare sum and placed in under the hood of my chicken coupe daily driver GN where it has been tortured to death...literally:biggrin:...for over 25,000 miles and made a hand full of comfortable mid 11 passes.

It finally gave up a valued appendage to get me to stop beating the boost out of it....as can be seen in the pix.:biggrin:
