I have a lead on some audi 5 cyl 20v pistons frmo a 1991 200q20v, and was wonderin if i can use these in my 1.8L 16v. if so what do i need? g60 rods someone told me but im not sure. anyways any info is helpful. also what comp ratio will i get? thanks!

The 20v pistons I have around here are slightly dished, with one notch for the center intake valve.

The 20v uses a longer rod that standard 1.8 motors (but not as long as the ABA)... I forget the length, and pin diameter.

If I get a chance, I'll get more info.... but of hand, I'd guess your C/R is going to be pretty low.
