We don't measure "how fast" something is.
the comparison am trying to do is for same year for sure as mentioned in my thread. between a 2007 stock STI and a 2007 WRX cobb stage 2. I wanted also to know if upgrading to VF39 is possible without engine modifications and with the Cobb Stage 2 what would be the Horsepower of the car.
Anyway I will check the Cobb website and if you want to share your knowledge, I would appreciate that. thanks
