I found my 16 valve motor at a parts supplier in the Atlanta area.  The motor supposedly had 89K miles.  I purchased it with the exhaust and everything necessary for the the swap.  I went ahead and replaced the belts along with the clutch and throughout bearing.

This swap was appealing to me for several reasons.  One, this would give me about a 30 hp increase (158 hp to 187 hp). Two, I could essentially make the car an 1987 944S replica.

Most of the differences involve the ignition system, including the addition of ballast resistors and a final ignition stage.  Also, the 944S DME needs an additional power source wired through the Fuse box.
