It's hard to tell from your list. I'm worried that your EWG setup might be designed for a rotated mount where your turbo is not (although they make greens both ways). If you're going EWG, I'd go rotated mount while you're at it. BTW I'd be looking more in the 800+cc injector range for a green turbo
of course you'll also need a good turbo back exhaust and a good tune.
Also, I think the green is too laggy for the EJ205 but whatever, you seem sold on it. Just remember to kiss your <4k RPM torque goodbye for me.
