broke my engine, need .020" pistons...

The 1.8 goes best with the deck at 15 off and the PTW # @ 004. Gapless rings and it will fly. It will come out vey close to the . 5 compression add.
I have not seen many stock bore engines that are unusable. I get them setup per above #s. The required hone is usually about 1.5 on a high mile engine. If the thrust bearings, are good, the bore will be good. IMHO, of 50 or so race VW engines. MM

If all you can get are standard pistons, you can have the damged bore block sleeved.

I would just go with the over bore.
