What makes the 16v engine different than the 8v besides the head

[Guest EBenjaminR]

As the title would suggest and besides the obvious of the heads being different what would make these two engines physically different.

Intake and exhaust manifolds

Cylinder head and cams

Timing belt

Timing covers

Turbo

Crankshaft

Connecting rods

Pistons

Timing

What else am I missing? What about what was modified to make it fit under the hood...

Fan shroud and motor?

As for swapping engines, has anyone actually done this? I do believe Ive read somewhere of someone building a 16v from scratch, if so was there ever a write up on the procedure?

Spelt shroud without the 'r' (see edit history)

16 v engine is nearly entirely different from the others

Fair enough. Would it be accurate to say that the only interchangeable part is the block?

its fair to say the block is the only part that the 8V and 16V could possibly share and the motor mounts that hold it in the car
