low pistons.... type R pistons are high, means that the piston head has a bump outward.
Low pistons are concave (or the bump is inward) so that creates lower compression... why do you want to do that for anyways? thinking turbo....

If you choose to turbo the F20B you'd be looking at getting a completely custom set of rods and pistons.

Personally I'd go with Eagle for the rods/pistons. They'd probably require you to send them a piston/rod combo to get some specs on in order to make you a set, I highly doubt they have any info on it, its not exactly a common swap in the honda world.

Keep in mind, its gonna be pricey.

Shouldn't have to, but if you're really serious about boosting you might as well just have the block sleeved.
