That is a coolant line from the turbo to the head that sits on top of the intake. And the J-pipe is a regular curved one that I have a stock rubber intercooler hose going to it, which leads straight down to the FMIC hard piping. But I did end up fiitting the intake on barely and everything is tight all around. But it was so tight that when i went to put the vaccum hose on the wastgate the little 1 inch needle on the wastegate Broke off. So now when i drive it The boost pressure is to its MAX and not 15psi where it was. Since theres no vaccum hose going from the jpipe to wastegate.so im assuming im going to need a new wastgate??? If that makes sense. I will get some more further pics away from the car and show you guys how everything is routed.
