Are FWD and RWD pistons the same?

[RCCC_DRiFteR]

Ok I go to order RWD SR20DET pistons and once again most places are out of OEM pistons but gladly remind me of the fact they have forged pistons in stock. However for my HP application I don't need forgerd. But here's my question, do FWD and RWD SR20DET's both share the same piston?? and if so what is the part number I can give to a Nissan Dealer to order. I looked through the sticky page for parts number and didn't remember seeing anything. Plz remember that it's also almost 4am and I'm tired as Hell. Any help would be apprecaited

The NA pistons are set up for a much higher compression ratio.

the piston or piston rings are set up for higher compression. But I was referring to being able to order SR20DET pistons from a Nissan dealer

RWD sr20deT pistons have a space at the bottom of the skirt cut out for the piston oil sprayer!
