Mike, you're posting in the Subaru Forum so the EJ motors are going to god here so there really isn't a point to get worked up about it. I think both engines are in all honesty really incredible.
Honestly, most people that own a EVO, WRX, STi could give a rats ass if the motor is capable of 500hp or 1000hp in
theory as most people that own one will never test the limits at that extreme level.
The point is that they already make 227, 250, 270, 300hp with AWD and all cost under $30,000 and all easily make much more power for under $2,000 in parts. There's nothing to get upset about.
