6-port turbo coolant line/oil filler neck (searched)
I know everyone is tired of 6-port turbo questions, but I just have 2 simple ones that didn't turn up in a search.
First, I only have an NA oil filler neck and will be using the stock TMIC for now. My gut reaction is that I'll have major fitment issues. Am I wrong? should I just hack a couple inches off of it and deal with pulling the TMIC when I need to add oil? Or go out and get a TII one?
Second is dealing with running coolant lines to the turbo. I was planning on running coolant feed from the nipple on the back of the engine and returning to the nipple on the back of the water pump. What I need to know is what to use for the line itself. Can I use Fuel Injection rated fuel line? or should I go with braided steel with some AN fittings? what size? If I go with the AN fittings how would I go about attaching those to the nipples on the engine and the turbo?
Don't think it matters, but car is an s4, will be using s5 turbo.
Thanks in advance for your help!

Agreed^
Answer 1. the N/A Oil filler neck will clear the TMIC. I've done it and was even able to add some oil with out removing the TMIC, although for oil changes i did... and later on i opted for the turbo oil fillter neck. The tmic will almost sit right on top of the oil cap.
Answer 2. The factory uses thread braded rubber coolant lines, fuel lines would be overkill and not nessary, but would certaily work, as the coolant system never gets aboug 20 psi, and the fuel system never even get below 25 psi.

Thanks for the info.
Yes I have a TII hood, not that newbish, heh.
fuel lines may be overkill, but it's better than the alternative, and also appears to be somewhat cheap. Just found it difficult to find coolant-specific lines that I could purchase for general use. Didn't know if the temp of the coolant was gunna be a problem with the fuel lines.

The only annoyance with fuel lines is that they will eventually bake and harden. If you want to go with AN, you can just replace banjo bolts on the turbo with metric to AN fittings. The engine side is a bit harder. Tap the water pump housing for NPT and then use an AN adapter. If the engine is disassembled, carefully tap the rear iron for a straight thread (like M14) and use the appropriate adapter. Otherwise, you can install a compression fitting on the rear iron nipple to turn it into NPT.
You can cut and weld the NA oil filler neck, or use the TII neck.
