2008 STI


My 08 STI is right at 340whp/350wtq on Dynojet, 300whp/315wtq on Mustang dyno. I am on stock vf48 turbo with e85 flex fuel tune. I bought the car with blown motor so I sourced a shortblock with forged pistons and rods, then took it to P&L Motorsport (which was a mistake, doing it again I would not source the motor myself because I ended up using a notoriously bad builder). The advice I received from P&L Motorsport was to get Killer B oil pickup tube & oil baffle windage tray, ARP head studs, P&L air pump block off plate, P&L stainless steel AVCS line kit (recommended for ringland failure), and IAG air oil separator. I have since added a Tomei turbo inlet and TGV deletes. This was all before going flex fuel. From my experience, brand matters so don't go buying a Grimmspeed AOS instead. Hope it helps, I am no expert, and I've certainly spent more money than most do to get to my power levels.
