Heres the deal. I have 00 b16 swap in my ek that smokes a little. It smokes on hard acceleration and when I down shift. I want to put new pistons in it but i herd I dont have to go oversized? They said they can even do it with the block in the car. I dont want to have to rebuild it again but if thats true I would rather use the standard size ctr pistons. Then spend more money in the head.
