Opel Insignia 2.0L turbo model

[TheKangarooMan]

Hello all,

I'm currently doing some research to find the model number of the turbo used on the 2011-2013 Opel Insignia 2.0L Turbo (the SRi model). I know the engine code is the A20NHT (LDK) model and it's a K04 turbo made by Borg Warner, but I can't seem to find the actual model number anywhere.

More specifically, I'm looking for the compressor map (which is proving tricky to find as well - Garrett seems to have them all over the place whereas BW doesn't). So any help for that would be much appreciated as well.

Thanks
