So i have a 2000 civic si, decided to upgrade since the old motor needs a rebuild. Tossed a GSR bottom end with the si head, the things all together and timeds and so on and so fourth. The question im having involves the waterr pipe in the back of the block. The GSR one is different from the one on the si block


Gsr pipe is a s follows if you can imagine it

From water pump side: big bung then a small bung then one bung on the thermostat housing

the b16a2 one

from the water pump side: small bung then 2 big bungs on the thermostat housing. Where do they go, can i use the gsr one?
