Project Caucasus is basically just a straight road up the west bank of the Caspian Sea, it only connects AZGE (at just west of Baku) to The Great Steppe. That's it.

Honestly just bite the bullet and have a clean profile with no map mods. Makes it way easier for SCS events. It's a lesson I learned a long time ago when some destinations would just lead to crashing if it was a Promods altered city.

Project Turkey isn't even a thing anymore, it was integrated (and upgraded, less of Turkey is covered but it's much higher quality) into Roextended. I think it becoming part of Roextended was when it was separated into AZGE
