which efi for my setup???

[ucmydust68]

ok, so here is the setup so far. 415ci small block chevy, sts remote mount twin turbo setup w/ the upgraded corvette turbos( i dont remember off the top of my head i will check tomorrow). its a forged rotating assembly with 8.5 compression using my pro topline alum. heads. i was wondering what efi could be used that is easy and not a million dollars, i have a complete edelbrock pro flow setup right now could i use pieces of it or all of it if i just switched to a different map sensor? or what would it take to use it? or what injection would you recommend?? thanks
