Should be the same, but the 11mm will probably use a different crank sprocket with a woodruff key and slot, versus the notched nose on the 1991.

im pretty sure only the very early 1.5L engines had the key and keyway. my 77 1.5D had a keyway, all my other 1.5s had the notch in the end.

i was actually told by a very reliable source that the early keyed crank noses are tougher than the later notched ones.. FWIW..

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.
