i'm considering putting the head from a 99 european m3 in to my US m3. i was able to get a full sheet of engine specs on my US version. does anyone know where i can find specs on the euro engine... I'm trying to find out the bore, stroke, compression ratio, etc. also if anyones ever attempted this hit me up with some feed back.

No one has ever done it, and i don't know if its even possible.
For the euro 3.2
Increased bore to 86.4mm (from 86.0mm) and lengthened stroke to 91.0mm (from 85.8mm) for a total capacity of 3,201cc (from 2,990cc)
Increased compression ratio to 11.3:1 (from 10.8:1)

i love how our bore * stroke is so square (3.0's that is).... just lower the compression and our motors are perfect for boostComment
