Ive searched and cant find any helpful info. Im looking for an overbore OE spec cast piston. Im rebuilding a CA18DET and for a friend and it has a significant scratch in #4 cyl. I know theres 83.5 and 84mm avail from CP and Supertech (as I have Supertech 83.5's in my CA) but we're not looking to spend an arm and a leg here, just rebuild to OE spec. Any help is appreciated.

I remember reading somewhere that someone used B16 or B18 aftermarket pistons (can't remember which ones) in their CA, and Honda parts are more readily available, so maybe that would be a worth a shot? I'm really going in the dark here as I'm not sure if this can be done, but I really do think I remember reading somewhere that they work..

OE pistons for the DET aren't available in the US. You'll either have to try and find a piston from another manufacture, or an aftermarket piston.
