1.4 convert to 1.6 - engine blocks

Is it possible to convert an 1.4 TS (146) with just changing some parts, to an 1.6 TS ?
An engineer, friend of mine, told me that its the best solution for power increase with low cost.
Later you can reprogram again the 1.6 TS for maximum gain.
The main engine block on the models 1.4,1.6,1.8,2.0 are the same or not?
Do you only need pistons or what else?Whats the cost ?
Can you do this to a 1.6 > 1.8 e.t.c

Some info please.Thanks!!

Hello... No, is the quick answer...
You will need to bore out the block to 1600cc from 1400cc. Then fit 1.6l pistons and redo the CPU. There may also be a difference in the air intake and exhaust required for the greater flow of air.
There is no way that you could just drop in pistons from a 1.6, your friend should re-evaluate that chapter in his books! wink
