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

compression, cams, injectors, oil squiters at the base of the pistons, but other than that I dont think there is much more. The rods could be a little stronger in the DET but I am unsure of that.

Anyone else wanna add to the list...

Hey everyone just picked up a ca18de as a spare motor for cheap, but what are the main differences mechanically to a det besides no turbo???? pistons?? block??
sorry if this has been asked before
