Hi I bought this a few years ago, guy said it was from a SD. I thought it was just a completely stock turbo so to save time I was going to build it with a WW2 to put on the excursio., alongwith ebvs pedestal delete. I need to pull the engine to change the oil pan. But looking it over the housing says 1.00. I was expecting it take say 0.85. Feels like some up and down movement in the shaft so may have to rebuild it if I use it. Here are some pictures thank you

 

Looks like a standard stock turbo. It's missing the wastegate actuator. The 1.0 on the compressor side is standard.

 

The 1.0 A/R compressor housing is stock for a '99.5-2003 Super Duty. ".84 A/R" would be stock for the exhaust turbine housing. It does look like the turbine housing may have been changed. Check to see it has "1.0 A/R" cast on it.

 

OK thank you for the information
