    18g will be like a 16g on a 2.0 still really responsive and good power

    20g will be a bit bigger, not as laggy but makes more power(duh, lol)

    It depends on your power goals and what ur using it for

    I have the TR also, i was saying that the 16g on a 2.0 is like a 18g on a 2.5. In that they are very responsive and still boost quick. Alot comes to the tune. I would get the FMIC and Injectors first and then get the turbo. With a 18-20 it will be better to not heat soak that TMIC.

    I am going 20g and have a couple maps set for Auto X and Street
