How much horse power does the 2004 Subaru WRX STi have?
the EJ257(17) in the 04-07 STi's was rated at 293 hp at 600RPM and 290 ft-lbs @ 4000RPM Reference nasioc.com
meant 6000 not 600
Well, the 04 & 05, at least, were actually rated at 300hp and 300ft lbs before the rating systems were changed.
My 06 dynoed at 243WHP and 253WTQ on a Mustang, stock.
