Which seals are in the Garrett T3 turbos?

[Clay]

Looking for rebuild kits I see some that say I need to specify seals. The three possibilities listed are:

1. Dynamic Seal
2. Encapsulated Carbon Seal
3. Four-piece Carbon Seal

So what do our Garrett T3 turbos have???

Our turbos use the carbon seal, though a lot of the aftermarket turbos use the dynamic, piston type seal on the compressor. As far as I know there is only 1 type of carbon seal, just possibly different names. The carbon seal is 1 carbon piece, a spring, and a small steel spacer of some sort.

TI turbos use different seals than T2 seals. Because with the t1 the compressor is under vacuum, but with the TII it is not.
