In USA I know J E Pistons in Huntington Beach. I am sure there are excellent places closer to home.

The best and easiest way is to use the Datsun Competition A14 cylinder head. It has the fuel-efficient and power-making "heart-shaped" combustion chambers (closed chamber head). Finding and buying one will probably be less expensive than buying custom forged pistons or re-machining Suburu Justy pistons.

See A-series Cylinder Heads.

will the stroke being different affect this in any way? and why a14 pistons wouldnt they be the same as a15 pistons?
