i think i read somewhere that coolant lines are not needed, but i wasnt sure if this was for a 14b or not. if i did run them i woudl do it off the iacv, but which way does the coolant flow, i am pretty sure it does matter, and i think that the right side of the iacv is the return, but thats just a guess.

You don't NEED to run the water lines, but why not. I just I just used the same connections that go in and out of the throttle body. Extra 5 minutes and few dollars to keep the turbo nice and cool.

^^^ exactly what he said, you dont have to have them, but if you have the extra time slap them on, The coolant flow can be either way, and it can be off your throttle body line, idle air control valve, whatever. Either of those little lines work fine, you can run to the auto store and get some 5/16 line and some T's and clamps.. you will be good to go.
