Im going to swapping them in together and taking out my K20A3 base motor. The only I'll probably do to the K24 frank set up is put stage 2 cams in with a valvetrain and a RBC IM, and put a Type S oil pump on it. My questions are, how reliable would that set up be? From what I understand, the K24 blocks are strong. They have beffy rods, strong counterweighted cranks, and good sleeves. Please correct me if I'm wrong about that. What would the compression ratio be with the Type S head and the A1 CRV block be? I just want to make sure it's reliable and make sure I don't have to do anything extra to make the block and head work together. Oh and one last question, will my base engine harness plug right in to everything on the K24A1 block and the Type S head?
