I am helping a friend from work replace the K20 in his RSX Type-S and need some advise on what maintenance items should be done to the engine before we stick it in his car. The engine in question has about 133k miles on it. We are replacing the waterpump, and swapping over his RBC manifold with a Hondata Gasket. New iridium plugs are going in also. So what else can you guys think we need to do to it before it goes into it's new home?
