i been looking to buy some forged pistons for my turbo build but i can only seem to find the part numbers for a2/a3 b16 is there any difference in the B16a or are they the same thing i wanna order the right shit the first time around. im pretty sure they are exactly the same but i dont wanna spend $500 just to return them for new ones or get stuck with shit i cant use.

I'm pretty sure they are the same. They are all 81mm bore.
