Where do I run my coolant return line? I've made a quick little sketch that shows what I'm planning on doing with my coolant feed and return line on my Rb25det. There are 2 positions where coolant can go back: 1 and 3. Number 2 is my coolant feed line. I'm planning on blocking my front coolant return line #1 and using the return on the block #3. So the coolant feed will go to the turbo and then it will flow downwards into the block. Is this okay to do? Will it cause overhearing or am I good to go?

What braided steel feed lines should I use on my GTX3576r that's on my RB25? I've recently picked up a gtx3576r turbo for my RB25! I have my top mount Manifold with a 44mm tial and a custom downpipe. But I forgot to recognize the oil and coolant lines for the turbo. I was thinking of braided steel lines for less heat. What sizes should I get for my oil drain/feed and coolant lines? Thank you!
