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 Syncrogreets, michael
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.

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.
