Are the coolant pipe, water pump and oil pump interchangeable between the Y8 and Z6?

 

Just went through a nightmare of a botched Mini me swap with a Z6 in my '99 Civic. I got it back to where it is a stock Y8 with a P28 and a harness from an auto with an adapter to make it run fairly well. During the swap, I noticed there is an extra bung for a coolant line on one of the pipes. I don't remember which one though. As for the water pump and oil pump, you could probably just check part numbers at rock auto or somewhere like that.
