F1x S63Tu turbo specs

I don't think I had ever seen this before - I knew the part code but never managed to find the turbine and compressor specs

Compressor side:
Inducer 45,69mm
Exducer 60,00mm
Trim 60
A/R 0,66

Turbine side:
Inducer 50,00mm
Exducer 47,32mm
Trim 81
A/R 0,69

I had always guessed that from the part code is would be broadly equivalent of a normal GT22 series turbo but with a 60 series compressor which is exactly what it is. It does seem a bit strange to me that Garrett only do a GT22 series turbine with a 52mm compressor such as this turbo

Then with a 60mm compressor you need to go up to the next size larger turbine.
