    B27 to 325i whats the compression

    I am wanting to know the compression ratio with a "i" head swap on an ETA engine? I am not looking to turbo the car its just something i have been wondering.
    Float like a cadillac sting like a Bimmer!:)

    You will get varying responses. I say 8:1.

      8:1 sounds right.
      The car makes it possible, but the driver makes it happen.
