I am trying to hook up my coolant line on my civic. I have a d15b7. Am I supposed to hook it to the really fat line on the intake manifold?

it's a hose that goes connected to the throttle body
run the cooling line from the back of the throttle body (back meaning closest to the firewall) to the turbo and from the thurbo to whereever that hose from the throttle body goes connected to. run the cooling line from the coolant that's coming out of the throttle body not the collant that's going into it. you don't want the realy hot coolant that came outta the turbo to runthrough the throttle body right afterwards.

yep... I used the loop from the back of the head to the coolant t-stat area. Works great. 5/8" coolant lines.

I did the same thing. The hose you take out is like 6 inches long. Comes straight out of the top of engine (behind the vavle cover) and goes into a little inlet below the throttle body. Take that out and run new lines to either side of the turbo.
