On my 03 996TT I have some oil leaking from my turbo into my intercooler hose. I want to rebuild my turbos.

I’m having trouble finding a source for t k16 turbocharger rebuild kit in the US. Can anyone point me to one? I have found places that can rebuild them for me but I want to do it.

Thanks,
Chris

Do you have access to or own the balancing equipment needed?

 

I partially agree that high speed balancing is a good idea but many guys rebuild there own turbos. They just scribe the nuts to the bolts /housings to match them up. Subi and mitz guys are all about this. For some reason we in the higher car bracket feel its so important.
But I do agree that it doesn't take much at 30k rpm for perfect balance to be an issue. But if you look in other forums you'd see it's pretty common practice to fix it yourself.
Some guys even say that there turbine wheels are perfectly balanced from the factory. So who knows, but I can agree that the insurance is nice.

 

Why don't u see if you can find the billet wheel. The rebuild is not difficult for sure but the balancing may be an issue. May be local shop that can do it. Usually $100 or so.

 

30k rpm? No they are not perfectly balanced from the factory. If we are going to go the "mitz" or "subi" world route... how much is their motor rebuild if the compressor comes apart and sends some parts down your intake track? I know the intercooler will catch the big pieces but what piece is big on a K16?

 

A copy and paste off Garrett site, for speed info only..

What is a wheel burst? Simply put, it is the failure of a turbine or compressor wheel to physically hold
itself together against centrifugal forces. At the speeds and temperatures reached by turbocharger turbine and
compressor wheels, the strength limit of the wheel material becomes crucial for durability and safety. Turbo shaft
speed can safely skyrocket to over 200,000 rpm for smaller units such as a Garrett® GT15, and even the largest
GT55s can reach a still astronomical 90,000 rpm without cause for alarm. Turbine wheels flowing highly-boosted
exhaust gas can reach 1800°F (980°C) and higher in typical turbo vehicles, and in top-level motorsports such as
WRC they can regularly get up to 1950°F (1050°C). The centrifugal stress that the wheel must resist is proportional
to the rotational speed squared, and the strength of typical wheels falls off drastically at temperatures above
their qualified limits. Wheels are designed to resist these stresses at high temperatures but there is always a limit;
a combination of excessively high speed and temperature is a recipe for burst.

 

You act if people don't repair there own turbos.
Cause they do all the time, not saying some haven't had problems (that could lead to major repairs) but majority have not.
I myself would get it high speed balanced and not denying that its the right thing to do, but to say it can't be done without it is not giving all the info.
I work on all my cars myself, and some might say that's crazy because as you stated the replacement costs on these motors are expensive to say the least Maybe we should all stop posting about our work cause most of us are not Porsche certified mechanics.
But I think there is a thing to be said about sharing all the info and allowing the person to make the choice for themselves.
Again not disagreeing with your opinion, as its the safest route but its not the only route.
Op there are lots of videos online on how to step by step repair or rebuild your turbo. But he is correct on the safest method to rebuilding your turbo albeit the most expensive but usual comes with a some type of warranty

 

I am all about doing your own work on your car. I have sent parts and even tools to forum members here. I feel that if you are going to go threw the trouble of getting your k16 off the car why take a chance? Now if there is even the slightest imbalance it will wear out the rebuilt journal much quicker the the original journal bearing.

 

A rebuild kit doesn't include new compressor or turbine wheels. So, if it was already balanced from the factory, then most people buy a rebuild kit simply because the seals have worn and they are leaking oil, which is exactly what the OP has said is the problem. That doesn't require a new balancing to be performed, as the rotating parts are the same as before.

If he's just replacing the seals, he should be just fine. Now, if he opens the turbos and finds out that the blades are scored and bent, then obviously, it's unbalanced and should be rebuilt by a shop.

 

Yes, however the compressor wheel needs to be indexed exactly as before.
