I may be getting a 2.0 5cyl for my Audi 80. Can it be stroked to 2.2 using a 2.3 crank (rest of this engine is in horrible condition) and some 1.8 pistons? I did the same with a 1.6 PP, crank from a 1.9 and pistons from a 1.8. Considering 1.6=2.0, 1.8=2.2 and 1.9=2.3 but with an extra cylinder, should the conversion be possible with same ease or are there some larger differences? Thank you all in advance
