No one really knows what the compression ratio is on the B20. I have heard 8.8:1 to 9.6:1. Even after talking to people in canada who recieve the motors directly from japan don't know what the compression is. I jus got finish swapping a b20 into my 94 LS and it is extremely stron. I have another one if you are interested. Mine runs extremely well and i haven't even put the type R head on yet.
