16V Turbo 85 (there was no 16V NA in 85) is different.

piston dish and head volume are a match for 85 only, changed in 86. (a bad 85 head should be replaced with another 85 head. 86-93 head will give a drop in compression on 85.)

pretty sure 85 big end bearing diameter is smaller than 86-93 but you would want to check

85 16V turbo cams are different from 86-93

85 was a transition year, first for 16V. I think that 85 16V crank/rods are probably the same as an 8V and 85 turbo pistons may be the same as 8V turbo but you would want to check

if you have an 85 and need a new block but have good 85 internals, you can put the 85 internals into the new block.
