Yes the Cosworth YB series engine will physically bolt to your Zetec tranny. There might be a problem with the cossies big flywheel though, the cossie use a 240mm clutch.
They are turbocharged in std. form although I believe that Ford Racing Performance Parts sold NA versions in the US a while ago.
The engine is rated at 204HP @ 6000rpm and 200lb/ft @ 4500rpm
Later version had 220 - 227hp and a bit more torque both peak and at a lower rev.
It`s a beautiful engine and very tuneable.
