Hi Ralph,
don't really understand your question.
all 1.6's and 1.9's up to TDI's ...
are conventional pre-chamber purely mechanical diesel engines.

the TDI ..starting with the 1Z engine code in 1995, in the US, in the Passat car ..
those have direct injection ( not pre-chamber ) and use a mechanical injection pump ..
and it's electronically controlled..
throttle by wire..
there are only wires and an ECU between your foot and the injection pump. 
More complicated of course..
buy more power and fuel economy too.

    if you have a stock 82 diesel westy , 1.6 NA ..
    you can't really add a turbo to that engine ..
    you 'could' if you got all the turbo parts ..
    about a dozen of them .......but those engines are quite delicate .
    At the minimum you should start with a 'real' 1.6 TD ..
    at least then you have piston oil squirters and a head made a little better .

    your best bang for the buck though ..
    is 1.9 NA ...very nearly a 100% 'bolt-in' ...good torque.

    if you have the stock DZ very low geared DZ transaxle that's stock oin 82 D. Westy's..you need to replace that with a better trans too.
