Curious why the GTX2860R is not an option. Same exterior as the 2860, but new GTX interior.

Also, trying to figure out if the GTX2867 will really do anything for a stock block build. So many choices!!!

Edit: adding compressor maps. Looks like at stock block boost levels, the GTX 2867R may not really be an efficiency gain compared to the 2860RS. But certainly has way more room to go compared to the RS:

Here is another interesting option: GTX2863R:

And here is turbine comparison, looks like GTX2863R is more efficient down low than the 2860RS:
