p72 itr are 81mm, b20's are 84mm. if you wanna use p72 itr pistons, get a b18a or b18b block.
if that is the fact that b20s are 84 mm you should be abull to use k20 type r pistons, in the g build the f23 are 84 mm and they say to use the k20 pistons so you have a 11.5 to 1 compression ratio...
and 84 mm pistons wiill not work in a 1.6, i beleive b16a is a 81.5 mm piston or even a 81 mm, i might be wrong so dont quote me, however i believe this is right.
