Hi,

Can anyone explain the systoms of a chipped turbine fin? Was driving my FC on the highway, and was pushing about 220Km/hr, all was fine till I slowed down and heard some vaccum sound. Thought was the apex seal, but compression seems fine. So pulled the car to a gas station, and pop up the bonnet. As I rev there was this metal clinking sound from the turbo. Mine is a garrett TO4e. Can anyone provide me this info, whether is it the turbine fin? Or something else? And what problems may arise if I dun change it?

Thanks,
Seven

 

Just pull your intake pipe off the turbocharger and look at the fins, it should give you a pretty good idea of their condition without much work. Check the shaft play and other aspects while you're at it.

 

Turbine fin or compressor fin? Turbine fin you have to pull the housing.

 

Oh yes, my mistake I didn't process that information correctly.

 

Well if you can hear "metal clinking" a spin of the turbo with your hand should give you a idea if you did some damage or not.

 

Hi Guys,

Think it's my compressor fin that has chipped. Anyway, am thinking of fitting a T66 compressor wheel in. What are the steps to be taken to fit it into the TO4e housing? And what is the cost for a compressor wheel like that?

Thanks,

The steps are as follows...

1)Take turbo to turbo repair place.
2)wait....
3)Go back to said turbo repair shop
4)Pay money
5)Drive away with your turbo

Seriously, unless you can balance something that spins around the 100Krpm mark, you should not do it yourself. (If that is what you were implying?)
