The K24 doesn't respond as well to modifications as the K20A (especially the R) if you want a demonstration on what a K20 swapped EG hatch can do with just 3boltons .... here it is http://hybrid-racing.com/images/gall.../Shorty1.1.wmv . Now imagine what a built K20 or just a K20 with a headjob can do (let alone a boosted one) .... pretty scary.
