alright i'm gonna be boosting my d16y8 soon, and need help with deciding on some forged pistions/rods. i am just about to sell my vitara/eagle setup, i decided to just go all out, so im gonna be getting my block sleeved soon from the guys at golden eagle, and i've just ordered my gearspeed tranny, and already have a head completely pnp with supertech valvetrain, and a bisi cam! which pistons should i go with and why if i want to run 400whp to 500whp? any help would be awesome!
