2004 18g 2.0L WRX wagon made 295Whp 274ft/lbs of torque on PIA's Mustang Dyno. 84,000 miles on the car and stock clutch still holding, car has been stage 2 since 15,000 miles and 18g was installed and tuned just recently. Tranny seems fine, I just shift it with a little more mechanical sympathy now
