| ohh those, those are just replicas of oem honda pistons, i heard they were pretty good, and the tolerances are pretty similar or are the same as oem pistons, i'd say that they're a good buy for the price |

| You should be fine with those pistons if you are planning for a lot of power, like less than 250. The item said they were good to 300hp, and that may be the case, but I wouldn't push it too close. Just take them with you to the shop with your block, and have the cylinders honed to the right spec. Since you have a couple of scratched cylinder walls, get .5 mm oversized pistons instead of the ones you listed, and get the block honed to spec. STD sized pistons are not going to work for you if the scratches are too deep.

| I don't know if it is the same company as the one you stated, but nippon makes OEM replacement pistons that people have had decent results from. |
