I am wanting to buy a block from my 98 civic EX... I was wanting to know what the best way to go would be? I have decided between a b18b and a b16a. Just because these are the cheapest and easiest to find blocks. I will be going turbo and possibly NOS(just for looks). I would like to know which block would get me the farthest in the long run. And also, just a side question. how much does it cost to sleave a b16 or b18? Thanks in advance.
