wondering if my stock jdm b16 rods would be fine or should i upgrade for the ctr pistons i just got. Also would i have to built the head somewhat or am i fine with stock valves, springs, retainers and etc. My setup now is a jdm b16a with a skunk2 IM, cf power chamber intake, exedy lightened flywheel, skunk2 cam gears, aem fuel rail and regulator, aftermarket header, tanabe exhaust, and etc. Do you guys think i should put these pistons in or stick with my p30's. Let me hear what u guys think.
