T3 5bolt TURBINE HOUSING? $60

UPGRADE: 360 DEGREE THRUST BEARING? $75

UPGRADE: WET BEARING HOUSING? $79

UPGRADE: TURBONETICS STG 5 TURBINE WHEEL AND HOUSING? $149

The T3 5bolt refers to the bolt pattern on the turbine side. I wasn't aware they offered any other bolt pattern for T3's, so you might want to email them and ask them to clarify that for you.

360 degree thrust bearing is an upgrade from the 270 degree thrust washer used in the turbos, it's supposed to help increase turbo life.

Wet bearing housing means your turbo will be water cooled in addition to being oil cooled. I would definitely recommend this personally, as it can help increase turbo life and slow the breakdown of oil due to high heat.

Stg 5 turbine wheel is a slightly larger turbine. Most come with a Stage 3 wheel. I don't know what the exact dimensions are though. You'll have to email them.

HPC Turbine coating is some sort of ceramic heat coating. Keeps heat in the turbo (good) and out of the engine bay (also good). Recommended but not required.
