Replying to Topic '6s engine vs SVT contour (2.5)'

Some Contour owners have replaced blown 2.5 L engines with 3 L blocks while keeping the old heads. There may be commonality of mounting points and bolt patterns, but whether other parts can be swapped out depends on the engine compartment layout.

Regarding the parts you specifically mentioned, the intake (an open cone filter, I assume) may require a different adapter to fit the '6 intake. By "pully," I assume you mean an underdrive accessory belt pulley. I wouldn't bother with that, since the benefit is dubious at best and you could well create additional NVH by changing the rotating speeds of the belt-driven accessories relative to the crank RPMs.

Oops... forgive the shorthand... AJ is correct. Noise, vibration, harshness. "Reduced NVH" has been a catch-phrase in the automotive engineering community for a good while now.

Actually, all the rage in the Contour community these days is replacing the crank pulley with a dual-mode damper (DMD). The DMD is designed to damp additional resonant frequencies of the crankshaft, smoothing out some more driveline vibrations as a result.

[EDIT: here's a link... http://www.spmotorsports.com/contour_engin...e_dualmass.html Ford added a DMD to the Mondeo V6 after the Contour was discontinued here, and now folks are selling the Mondy damper as a direct replacement for the Contour's stock pulley.]

If I had to guess, the '6 already has a DMD. If Duratec6 was actually referring to a DMD, then it may be redundant to scavenge your friend's.
