E46 turbo help

I’m planning to turbo my e46 and I need to know what I need to get for everything to work. I found a turbo kit so now I need to know what injectors to get that will fit on a m52 and also what fuel pump I need. I’m also going to install catless headers and I know I need a tune but I’m not sure what I need to get as well or who to go to. Aside from that I’m not sure what else I need. Can someone help me with this?
