I'm new to the K series game I want to know if i'm planning on doing a K24 bottom with a K20a2 head swap. Is there a difference between the CRV(K24a1), ACCORD(K24a4), and TSX(K24a2) bottom end since i'm swapping the head anyways? i know that i have to change the pistons to K24a2 are there any big changes in horse-power and Torque between the 3? Please help me out people
