This is a topic that I see was discussed years ago but I couldn't find the info I was specifically interested in. So....
1) assuming somebody was able to find a cheap source for four of the 1.2TDI pistons and rings from a late model VW polo, are the piston pin diameter, piston pin location, piston diameter, etc. the same as to be a slip in to an early model NA 1.6 diesel block with 1.6 rods?
2) are there distinct differences between the NA 1.6 block and the 1.6 TD block, rods, crank, oiling, etc.?
I love the idea of putting together a 1.6 mTDI engine which could deliver the most power and ECONOMY from a smaller displacement engine.
Seems such a frankenmotor could easily deliver 75 hp and return 60-70mpg in a 2,000 pound car.
