Maybe Nüral? 1,2 has 76,5mm bore and 24mm piston pin, that info can be found from Etka. That's all I know of that engine.
hi,
I am currently building a 1,7l TDI using a 1,7 SDI (engine code "AKU")
The crankshaft, conrods and pistons fit perfecly into every 1,9l DI block.
The plan is to use this engine with stock 1Z/AHU components in my VW T3 Syncro
greets, michael

a 1.7 SDI is basically a TDI already, just without a turbo..

Need more info on this
. I really would like to do a 1.6 TDI.
Find me a 4th and I will.
Alcan manufactured the 1.2L TDi pistons.
But I've not find anything on his site to know more about this pistons...
I do understand why someone might want a 1.6TDI to keep the old 1.6TD block fleet in heads into the future, but, honestly, if one is looking for economical engine - just buy a 1.2l or 1.4TDI and bolt it in. The friction from 3 pistons will trump that from 4 any day.
If one is fixated on 4 cylinders, then just start with a 1Z or AHU and put 20% taller gearing in place. Now you have the same swept volume at the same road speed as the previously geared 1.6 4 banger - and you don't have to diddle at all with the engine. Friction wise, the reduction in engine speed should proportionally offset the extra ring-to-wall drag from displacement.
The bonus, of course, is that you can just drop a gear and have all of that 1.9 litre sweetness when you need it - at no extra cost.
Some times, the pragmatic solution is just hiding well behind the obvious.
I still am kicking this idea around. I may just buy those pistons and start measuring while the 1.6 is on the stand.

I'm OK with you.
But, for me, building a 1,6L TDI is more difficult and interesting than swap a 1,4L TDI!
