VW 1.8 engine block - simonsmith473©
I have a vw 1.8 engine block. If i get bored out to 2 litres, does anyone know if i can simply get bigger pistons while leaving the stroke and crank alone?

I'd be surprised if you could get it bored out - has somebody offered to do this for you ?.

The "normal" 2.0 VW engine has both larger bores and stroke. I dont think youd find big enough pistons to take it to 2.0l without changing the stroke, ignoring the minor problem of boring into the water jacket.

Other problems:-
Head cobmustion chamber.

The 2.0 pistons could have the gudgeon pin mounted
higher in the piston (or it could be the con rod)
to cope with the longer stroke when used
correctly.
