The SVT focus is rated at 170bhp not whp. With transaxle loss it will usually dyno around 150 at the wheels. I'm not sure if the head casting is the same as the regular zetec. Mind this though not everything the svt has will be a DIRECT bolt-on. The intake cam has a different keyway for the cvt and the Intake manifold has dual stage runners. I know of a couple gents who have bolted on the mainfold along with some serious modification to the pcm to get it to change runners. If anyone really wants to go the svt route. Best bet would be to purchase the entire drivetrain along with all wiring and pcm.
