Alright guys right now i'm running .45 bar. I want to go up to 11psi of boost(.75 bar) please let me know what hardware i'm missing to get up to this. I'm going to get a wideband 02 so i can tune myself. and then dyno tune it when i'm pretty close to what I can do.

current setup
stock b16a2
precision sc44 turbo 63 exhaust
dsm 450cc injectors
VAFC
(i have a walbro 255lph just sitting, not installed yet)

I should just have to install the fuel pump and up the boost and tune? Anything I'm missing or should be replacing? thanks
