is anyone running the 6mge with the 9.2 pistons or higher. I was told they came stock with the 8.8's. if so what kind of power? if not what kind of power could you expect. p.s. is it the earlier years or the later years alternator that has the internal regulator.

re:

Correct me if I'm wrong, but I believe the 6M uses the 8.8:1 compression pistons from early MKIIs. Given it increased stroke though, the end CR comes out to be 9.2:1, same as later MKIIs.

Ditto on the above statement. I currently run 10.5:1 compression in my 6M. Works great except I can't drive it anymore because it won't pass a sniff test with the higher compression.
