CamB 48 Report post Posted February 13, 2009 The standard 2002 engine had 8:1 - once upon a time it was common. If you want 92mm bore (not 93.4) have a look for M30B34 - it appears to be the same bore and stroke by the looks of my 5 min google, but 8:1. I have no idea if this link will work: http://www.motorenteile.mahle.com/eLIZA/ap...243#spa45034123 It's possible it is a USA only engine. I wouldn't know.
