What Makes up a VW Turbo Diesel !
There are a few differences between the Turbo and the Non-Turbo Motors.
1- Starting with the Head The regular head is Cast in aluminum-alloy.
While the Turbo has a stronger, sodium-injected alloy.
I seen sodium and tasted sodium ( not by choice )
Just like Loren I have a bit of problems with this one . I know it is a better alloy
but sodium ? ---interesting . Must be a typo.
IMHO after reading the SAE papers on the crank ---I say a lot different.
But I still say with care --a NA crank will do the job.
Sodium melts at 97.7 degree C --- go figure. Sodium looks like low temp solder
and can be cut with a knife.
PS: How do I identify the tortional damper on my Turbo ?.
A number of changes were made to the crankshaft. The front end of the crankshaft was reinforced. The highly loaded crank-pin, at cylinder 4, has its radius induction hardened and the oil hole ground while radii at the other pins are roll-hardened. A torsional vibration damper is used.
