Do some reading at www.subarureview.com and the 'stickies' and forums at

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:

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
doing.

Are you certain what you're doing?
