Turbo Parts
Since many people have never seen a turbo together or apart I thought I'd put together this photo collection of my turbo during the rebuild. I didn't put pictures of all the seals, bearings and other small parts since they just keep the thing running but aren't part of the turbo mechanism.

Turbo Together without the wastegate actuator |
|
The Center Housing and Rotating Assembly (CHRA) where the oil and coolant lines attach. This is where all the bearings and seals are contained and fits between the exhaust and intake assemblies. |
|
This is the Compressor (Intake) Housing. |
|
This is the Turbine (Exhaust) Housing. It is a Cast iron material and is prone to cracking. This is the heaviest part of the turbo and contains the wastegate that opens when the intake pressures are at their desired limit. The wastegate prevents the turbo from over pressurizing the intake. |
|
The exhaust turbine blade is one piece with the shaft that goes through the center housing assembly and connects to the compressor blade. This turbine blade spins from the exhaust pressure which then spins the compressor blade attached to the other side. This assembly can spin at over 100,000rpms. |
|
The Compressor blade fits inside the compressor housing and attaches to the turbine blade/shaft assembly. |
 |
Here are the two blades together, when assembled the center housing and rotating assembly is between them. |
|
This is the wastegate actuator. It keeps the wastegate closed until the intake is at a specific pressure then allows the wastegate to open. The bottom picture is the actuator mounted on the turbo assembly. |
