i have a b16a2 with an a2 tranny. i have rc 550 injectors but otherwise stock. i have a small knock in the bottom end. i am gonna go ahead and rebuild the bottom end. i have scat rods and i'm planning on turning the stock crank. i was looking to find the best pistons for a reasonable price. if anyone could let me know some good ones and maybe post a link to where i could get them i would greatly appreciate it. thanks in advance
