Were GNXs .82 housings? If so I'd forgotten that.

This may be...I was not involved with this part of the development of the vehicle....the only question I would have is the particle trap on the turbo (shown on this turbo) was added after initial development of the turbo ..but everything looks correct.

Side by side

Does anyone have a side by side pic of the housings, I had thought they were they same also. I thought the only way to tell was the contamination trap and the number tag's having XXX in the number.
This is what is posted on GNX.com

Turbo- a modified T-3 turbo was used with a ceramic impeller wheel, which provides a lighter rotating assembly for quick spool-up and more efficient operation at higher boost. This led to concerns that rough (factory) wire-feed header welds might dislodge under stress and shatter the ceramic turbine wheel. They addressed this fear with a contamination trap on the turbine wheel which is unique to the GNX turbo. It looks like a "bump" on the exhaust side. Replacement GNX turbos DO NOT have the ceramic wheel, so be careful with your original.

The compressor A/R remains .60 and the turbo is equipped with an adjustable wastegate. The stock turbo cover was swapped out for a more attractive unit. Prototypes said "Buick Turbo" while the production units simply said "GNX".

That is the real deal, I had two of the that I got from Mclaren, The X in the part number is an experimental unit form Garrett, I spoke to a guy there to confirm. I sold them to John Dagata from Bowling Greeen Customs many years ago, I see this auction is in Ga where he is/was. If you check the feedback from other items sold it sure appears to be him, name John, mentions BGC by name, etc
