You can get an adjustable cam gear to advance or retard ignition timing but you cant adjust anything on the cam itstelf. The only ajustable lift cams are on the new BMW V8's and V12's and even then the cam doesn't change they just mechanically change the pivot point for the rocker shaft which changes lift and duration.
as he has heard of the 318's having adjustable cam gears. i was telling him which engine did.
