I'm a noob. Recommend a turbo?
A turbo that flows a hair under 300cfm @ 1.4bar pressure ratio would be a good starting point. From there, check out different compressor maps and find the one that those 2 numbers will be closest to the peak efficiency island on the map.
A20's love boost, 6 psi on a small turbo is ----. After seeing the motor you posted I'd say look into a garrett t3 60 trim or something close. Rpm's limit your topend, so a .48 a/r exhaust housing would reach boost threshold in a timely manner and not choke up at your 6500 redline. Go for around 8psi off of it...you'll love every second once it's tuned.

on the focus that is also 2.0, i use the t3 .48/.60 60 trim and it works very good. Stage 1½ even better.
Even faster spoolup?? Go GT2554R BB or maybe twin turbo it with some tiny gt12 turbos!!
