Default help identify this turbo

Hey there i'm trying to figure out what kind of turbo i have as i'm not an expert on this. I bought a kit with this turbo included. I was told it was a pt76gts when i bought it but now i'm being told differently. Can someone tell me what kind of turbo it it?

I"m not sure who to point the finger at phil (seller) or mike at azps kit designer. but that whole transaction was full of bs. If this isn't the turbo that was advertised with the kit i'ma be a little angry. But i guess i should have done more research before buying.

there is also "TDM 42 4S" printed on the back side of the compressor housing if that would help identify it. I've searched and i can't make heads or tales of what it might mean. Big thanks in advance to anyone who can help.

Here is a a pic of my 60-1 on the left and a GT35 on the right. So judging by the pic the compressor wheel is definitely bigger. Only way to tell for sure is to take some measurments.

Take the cover off on both sides. Measure the compressor wheel both the big and little side of it and then take the turbine housing off and do the same. We can then tell exactly what it is.

I"m not sure what style flange my setup uses. Most the t4's i see have a split in the middle. Is it just the dimension of the holes that signifies a t4? Or do the fact that i don't have a divide in my turbine shroud mean it is a t3 flange?

the closest thing garrett has to my compressor wheel is the 4294R. However nothing on garrett's site matches with my turbine.

Anyone have any thoughts with the measurements i posted? Like I said the closest compressor i found was the compressor from the 4294r but the turbine on the turbo was significantly bigger. Also i don't see where garret even sells a turbine cover with a .96 A/R. Can anyone help with this? I'd kind of like to know what i can be expecting from this turbo before i go install it. Thanks.
