I've just ended my first subaru ride. It was quite fun

. However two things that should be resolved. In tight circles sometimes there's a subtle sound coming from rear left wheel. It's not knocking - rather delicate rubbing - could be pads but if not pads would it be a BIG ($$$) problem? Another thing is turbo - I'm sure it doesn't pull how it should. Over 200 hp should act in different way. There's no lag at all but car starts pulling just after 4000 rpm. So possibilities are:
1. shot turbo - but it doesn't smoke at all
2. shot or burnt wastegate
3. something with electronical system - in saabs we have APC I don't know what it is in scoobys. I assume here is also base boost which is increased by SOMETHING depending on knock sensor and inlet pressure and perhaps something else.
SOLUTION (means - my ideas)
The easiest one is unplug wastegate and be gentle with acceleration. If car starts to pull, turbo is OK and I need to find another thing to fix. But how to do that? Could anybody post a picture and point a wastegate hose to me?
Am I right? Or there's any other way to check if compressor works? Thanks for every answer.
And hey, where is intercooler? At the front? Or I am goofy and scooby has 2 radiators?
