I highly doubt that it has h22 pistons I believe the F series motors have short pistons like the K motors. I am sure they may be the same bore. I preferably would put a 87mm crank in it from the 2.2 and then bore it to a 89 or 90mm and have like a 2.3-2.35L and have WAY better r/s ratio. A tsx crank in a F20c would have some SUPER short rods if the block is shorter than a k24.
