heads are the same, inlet cams are the same(i think), exhaust cams have a different lobe centre but same lift and duration
pistons are flat top in DET and domed in DE
cranks are the same, rods are the same
blocks are sorta the same, DE just isnt drilled and tapped for oil squirters and turbo water line
inlet manifold and throttle body is the same, most sensors are the same, temp sender for the computer is a different colour, dont know if thats a year thing or a DE/DET thing

pretty much everything else is teh same
