I am having no luck trying to find a new (as subaru dealers have no stock anywhere in the world) or even decent second hand serviceable HF3 factory forged piston that came in the last of the V3 wrx and sti - sti RA's. I thought I would make a final shout here to see if anybody has a number 2 cylinder one available.

It will have L stamped on the top of the piston A on the bottom and an arrow pointing to the left side, it will also have HF3 cast on the underside.

If anyone has one available or knows where one can be sourced please PM me or reply here before making my final decision to completely tear it down for full rebuild.
