I'm not expert here...best bet is to check out the DSM boards and Subie boards. Also keep in mind that they are usually a single turbo running a single DP. In our case our 2.7T is more like two 1.35 3cyl engine using a 2.5inch.

As opposed to a 1.6-2.2 running a single 3-4inch DP. My numbers are rough...but you get the idea.
