You should only consider the T28 over a 16g if you seriously lack mechanical skill to do a little extra work. Everyone and their mom is buying an EVO 3 16g these days for hundreds less and more airflow. How much boost you run isn't important, it will be determined when you tune your car. Somewhere in the neighborhood of 20psi on this sized turbo for pump gas. A 16g can do something like 350whp on average if tuned well, a T28 should be a little less.
