I am still thinking of the finishing touches on my 2nd turbo set-up. What are you guys using? Anyone with copper pipe? Did you heat it to bend it? Anyone using just hose? and if so what kind are you using that doesn;t start to crimp and bend with the heat?

I've had pictures up years ago and even recently of my drain.

The whole piece is copper pipe, 1/2" diameter with a compression fitting in the pan. You can unbolt it easily from the turbo and the pan and remove it. You have to use the pipe and buy the 45 degree and one 90 degree elbows. THen you use plumbing solder and a torch to put it all together. THe beauty of it is that the 1/2" compression fitting fit right into the turbo drain piece that came with my turbo and I just bought one with a 1/2" tubing exit, then I routed the pieces and pre assembled them since they are all slip-fit joints. I took about a half hour with a hacksaw and the elbows to make a nice sloping drain down to the pan, bypassing the exhaust, etc. Then once it is in place you just mark all the joints with a black sharpie with a line perpendicular to the joint seam. then pull it off and solder it all together. If it isn't right, or you need adjustment you just melt the solder and adjust till it fits.
Once complete it will last the life of the engine I'm sure.
