I'm sure he'll be thrilled. LOL.

That brass stock is expensive. We're working on a different machining approach to the aluminum. Aluminum stock is significantly less expensive, even when much larger.

What's the difference between the N/A & turbo caps?

Arrangement of single or double nippled caps and the crossover is in front of the intake away from the heat of the turbo. In reality ALL can use the turbo setup so that's all I would concentrate on making, more universal.

Someone said in another thread that someone installed their turbo and kept the lines N/A style to avoid the dead-heads, anyone here that did it? Did you put some kind of insulation?

Cool. I'll be doing the same then when I get the new caps as well.

I guess the line running across the valley pan can't be any any worse than the diesel pouring all over it from leaking caps, to look at it that way!

Those look great, hope they hold up. That would be nice not having to replace plastic caps anymore.

The material cost on the brass caps exceeds the cost of a regular return line kit you can purchase online.

It's supposed to get into the low single digits and possibly below zero around Wednesday. I want to see if I have any issues.
