I would to get some suggestion or pics of different methods of plumbing the oil coolant lines with out using black rubber hoses and gear clamps.

I was planing on using -6AN fittings on the turbo side but what to do when i get to the coolant nipple? Turbo oil drain is getting-10AN fittings with Teflon hose so that's covered.

you can drill and tap the water pump housing where the nipples are. its really quite simple and definately easier than it sounds. but sometimes its harder to fit the lines than make the firrings work, look for the super flex stuff from earls. it helps A LOT!

The superneat option is to have alloy male AN fittings welded onto my waterpump/thermostat housing and connected my water lines to that.

I removed the nipples and had a local guy weld on two -6 nipples to the WP housing


I've then used -6 lines to link it up - about to replace them all with Teflon. Can't get photos until the weekend though as it's dark when I get home.

Exa toy the same as what I had done except I used -8 and put one where the heater line goes back in as it's no longer required on my car. The white looks good I'm interested to see more eng bay pics.

You can use Earl's superstock hose in -6 size with push on fittings for the turbo side and a tight fit over the nipples on the water pump housing. Same hose in -10 works for the heater hose that runs from the water pump housing to the fire wall.

Here's one of my turbo coolant lines before being fire sleeve'd.

In these pics you can see I'm using the superstock hose for some other coolant lines.

Here's a link to the hole album from my build if you care to see how other lines and such were done.

If I were starting over, I would tap the water pump housing for adapter fittings and not use weld-on fittings with the cast water pump housing. The air pockets in the casting caused some leaks.

While we're on this subject, are these eBay special -6AN lines with barbs any good? Looks like the M16 x 1.5 fittings (in blue) are correct for my turbo's CHRA. http://cgi.ebay.com/ebaymotors/ws/eB...m=180605776185



Oh, just noticed the barbs are .475". That's almost 1/2". The nipples on my waterpump are only 3/8". I suppose if I got a set of these 3/8" barbs to replace them I'd be fine. http://cgi.ebay.com/ebaymotors/6-x-3...item35aeaac2a3

Thoughts?

Are you running -8 lines all the way through, or using a step down converter? I thought about it but -8 seemed a bit of a pain with the bend radii etc.

Main problem with running swept fittings at the turbo is that I need to disassemble the whole turbo to loosen/tighten them, due to the space restrictions - can't get a spanner on there Dunno if that's something specific to the 35r setup though.

Brad - there are a few more bay pics towards the bottom of my build thread here:

That look nice but I wonder if the lines are good quality.

i wouldn't really trust the quality of hose that you'll find on most ebay specials, get compression fit an adapters and some high quality braided line suitable for oil/coolant. i wouldn't doubt that those hoses are actually teflon plumbing hoses... they sure do look like plumbing hose you can find at most hardware stores.

Though they look nice, I wouldn't trust most of the items like this off of ebay. Besides, what is the point, other than the "look", of having -AN fittings and high pressure line if it has a barb end on the other side???
