hey guys, looking at buying a 2008 2.5 Turbo Outback - anyone have experience with these? What are they like economy wise when driven 'off boost'? they have SI drive - i have had a 3.0R in the past so wondering if they compare to these in fuel use? How much do you guys use when driving a similar age 2.0 turbo is the 2.5 turbo a good reliable unit? any indication of when things are likely to go pop (ie turbo blows at X,000km's) thanks heaps
