I have a F20B in my car with a bore and stroke of 85mmÃ—88mm which equals 1997 cc. how could i increase displacement without boring out the cylinders. I have a idea about the H22A crank and rods in my F20B (assuming they have the same exact blockheight) to get more diplacement. How would i calculate this to get cubic centimeters? Any help from Geniuses/Mad Scientists would be appreciated.
