you can't overbore FRM sleeves. SOMETIMES you can get away with a light re-hone of the cylinders and run new standard size type S pistons and new rings. While you're at it, go ahead and pick up a set of eagle esp rods and ACL bearings. My last H22A I built was a jdm type S. I kept the oem pistons and got new rings, eagle esp rods, and acl bearings. It ran good until the kid I sold it to ran it with 1/2 quart of oil in the pan. He went like 20k miles without changing the oil. Then he tried to say that it was my fault since I built the engine myself.
