Siemens to Bosch on bkp engine

Hi guys I’m new to this forum and be reading up on the Siemens to Bosch conversion people have been doing and wanted to know if it’s the same for the bkp engine and if so what exactly will I need for it to work as I can gather I will need injectors , injector loom, wiring from engine loom and the ecu but what about the solinoid block from the bkd as my bkp as two separate little solinoids plus mine as an electric egr do I just have this mapped out the ecu any help will be much appreciated thanks again Mathew
