original 2.8 non vanos?? sound more like a original 2.8 vanos mated to a non vanos head to me.
anyway mind sharing where you guys saw the halfcut? if the chop shop can tell you its a original 2.8 non vanos without a blink in the eye, its good to be cautious with them... they should be knowing their engine inside out instead of quoting what the jap dude said..
