this quote is way wrong.
[quote]My car builds boost slightly quicker because the turbos are smaller, but, with a big turbo you will get more airflow through the system on less pressure.

your car builds boost slightly quicker because you have better turbos… bigger or smaller turbos have no effect on measurement of boost. Boost is the measurement of restriction. your measureing how hard it is to push air into the motor. Rs6 or gt36 boost shows you how hard you have to work to push in a set amount of cfm. That is deterimined by the system not the turbo.
