    LQ9 piston suggestion

    What recommendations for pistons would you guys have for a Lq9 street build?? Would like to retain stock compression. hypereutectic Or forged? Would like to go hypereutectic If itís an upgrade over stock because the noise associated with forged. Might see a mild shot of Nitrous every blue moon. How do the stock rods hold up??? What are other upgrades needed to be done when going over this motor? Whatís a good brand thatís reputable that wonít break the bank? Thanks in advance

    DSS is a solid affordable forged piston. doesn't break the bank but better than stock. I'm running them in my 403. With my rods and crank I should be able to handle up to a 300 shot. At least on paper.

    Stock pistons with stock ring gap can handle 100 -125 shot. Above that not so much....
