Could you Bore a B20 out to a 2.2L and use H22A forged pistons amd rods, or is that a negative.

 

It won't be 2.2L but you can use the 87mm Pistons. (I think there 87mm......)

You would have to resleeve of course. $1300.00

 

If you bore the cylinders to the same dimension as the H22A then you should be able to use those pistons. As for the rods I highly doubt it. I'll be interested to read what others post on this topic...havent had much experience with b20's or h22's
