    Offroad cams? Who are you talking to? What is your intended purpose?

    For one thing, this car isn't as amenable to engine work as, say, a straight
    6 or 4 or even a v8. Valve covers, due to the boxer's very nature, are
    about 2" from the wheel wells, so while possible, it isn't a damn bit easy
    to swap cams without pulling the entire engine.

    Mr Jones,

    I don't understand what you're referring to. There is no such thing as
    offroad cams. There are variations in lift and duration; most who usually
    swap out their cams do so to allow their car to breathe more efficiently
    than oe cams allow. Many of them do so in concert with full head work, from
    enlarging ports to deburring casting flashes to strengthening drivetrain
    parts. Read up on it here: Cylinder Heads/DPR Subaru Cylinder Heads.htm
    and here: Valvetrain Components/DPR Valvetrain Components.htm

    Further, anyone can unloosen bolts and pull a motor. When you begin to open
    your engine, it's much more critical that you're certain of what you're

    Are you certain what you're doing?
