Outer Limits 4x4 Board

I was looking at a range rover yesturday and the owner told me that it had a Land Rover Discovery high compression 3.9 in it that was only released overseas. He said that the compression ratio was over 9 to 1. I am curious as to whether such a engine actually exists and what power and torque outputs it has.

Any information on this topic or suggestions on where to look would be greatly appreciated.

Local Rovers with 3.9 had 8.13:1 Compression, Units released overseas had 9.35:1. If you look on the left hand side of the engine where the engine number is stamped just above it should have the compression ratio stamped in as well I think.
