Theres all your info on the drive train on a SVTCDrivetrain Differences
The SVT Contour has many high-performance improvements to produce more power and withstand harder driving than the normal Contour models.
These changes include:
* Changes to the camshaft include a longer duration and a complete change in valve timing points.
* Higher compression: 10:to1(SVT) vs 9.7(normal)
* PCM was more aggressively tuned and required premium fuel.
* Larger throttle body (60 mm vs 54 mm). Lifted from the 3.0L Duratec.
* Intake manifold and primary intake ports smoothed by ExtudeHone.
* SVT-Clutch.
* A water to oil, oil cooler to keep control of oil temperatures during performance driving.
* A radiator with a thicker core for better cooling(lifted from Saudi models).
* Different air filter and intake (cone style using same air filter as V6 Mustang).
* A lighter flywheel(from 21lbs to 19lbs.)
* A larger-diameter, quasi-dual exhaust.
These changes allowed the SVT Duratec to make 200hp at 6600rpm and 169lb-ft at 5500rpm. The rev-limiter was also raised to 6750rpm from 6500rpm.
