i recently acquired a full h23 engine but it is in pieces, with the block i am putting a h22 type s head on it, the head however i don't know what to do with it. i have already taken the injectors off and put them on my motor and i want to swap the intake manifold over to my f22b1 but i don't know if it will work. well the reason i ask is there is on the back of the block a oil cooler, i know that they are not on f series blocks only h series so my question is what do i have to do to make this compatible to my f series block? is it a simple swap over over or do i need the h23 water pipe to make it fit and is it really worth it to spend the time to do it? i did some reading on honda-tech but that really didnt help so i know someone on this forum can help.
