Replying to: vlad12 (Feb 09, 2009 7:06 pm) Well, 2 things.   * the Forester is lighter   * the power in that engine is under-rated, big time.   Here is a HP/torque curve from a tuner, before and after. Note that the "before" is 265hp with 91 octane gas and 270hp with 93 octane.     All these engines have plenty of power, but I'd lean towards a turbo. Then drive the two to see which ones handles more to your expectations, and pick that model. You won't regret it.

Replying to: ateixeira (Feb 10, 2009 11:28 am) Could Outback's engine be tuned same way? Or Outback's engine is on the peak from the stock? For example COBB unlocking an additional 35 HP (power) and 40 lb-ft (torque) from a Legacy GT and increases boost to approximately 15psi. http://www.cobbtuning.com/images_products/3733.jpg   In that case Outback is more powerful again (but you are right more heavy) Probably I need to try to drive both again (and Impreza, by the way) Replies to this message: ateixeira (Feb 11, 2009 8:25 am) kurtamaxxxguy (Feb 17, 2009 9:25 pm)

Replying to: vlad12 (Feb 10, 2009 12:28 pm) That curve says STI, so that's not for the Legacy GT, AFAIK.   The Legacy's turbo has more boost so it probably does make a little more power, one would expect. Replies to this message: kurtamaxxxguy (Feb 17, 2009 9:25 pm)

Replying to: ateixeira (Feb 11, 2009 8:25 am) http://www.cobbtuning.com/products/?id=4318   is the location for the '09 Forester maps and the PDF's that explain them. It was explained to me that the Forester is "riding the edge of detonation", and that increasing the richness helped overcome this issue.   The big questions are: 1. when the user remaps the engine, is it possible for user to __completely___ reverse the mapping back to the original stock mapping? 2. what will Subaru do if they discover the engine mapping is changed (I assume they will void the engine and possibly entire power train warranty).   My apologies to Edmunds if posting this link raises any issues.
