OKay, so my junkyard tt is coming along nicely now, but I have a question for you guys. The piping from the turbos to Intercoolers, to throttle body, does it have to be metal? I was looking at my friends eclipse and all of his lines are rubber, and the point being, rubber lines would be a hell of a lot easier to run through the fenders and back again then metal with rubber elbows. And if they could be all rubber lines, where would I get something like those lines?

depends ont he boost levels you will be running, Anything under 8-10 psi and rubber will be fine. As you move up to higher levels you want to run the metal piping due to the flexing of the rubber, as the boost gets higher the tubing will expand in the rubber setup.

make sure you get the proper clamps for all the joints on your setup as well. Low boost and regular hose clamps will be fine, but as the boost gets higher you might want to look at some of the spring loaded clamps that hold a lot better.

Turbo hoses aren't rubber, they're silicone. stuff works fine, and it easy to run, but it isn't that cheap. Metal might almost be cheaper.

I have seen people get away with PVC...but if it fails you didn't hear that from me
