Turbo and Oil cooling lines

[Galipso]

OK so i've browsed these forums and can't figure this out. Some legit help would be huge right here.
Set up is 1G bottom end, 1G water pipe, 1G thermostat housing, 1G oil filter housing, 2G head
I've uploaded 2 pics, all color coded questions-

Thermostat housing pic:
Which one is the turbo coolant return line: Red or Blue?? Once identified, what is the other color for??
Green: Emissions Control Thermo-valve.... what does this go to? (ive eliminated the emissions) Can i cap it?

Engine Pic:
Purple is the turbo coolant feed line: Do i have to have the 1G OEM piece to bolt into it? (Yes the oil feed from the head is just above it but this will be removed since i've read it's a poor oil feed)
Yellow: is this the new turbo oil feed?
White: No idea what this goes to...
Pink: No idea what this empty slot is for...

Thanks in advance guys. Let me know if you need any more information.

Ive read this one over and over. This guy has a 2G thermostat housing and a different oil filter housing than me

Thermostat housing pic:
Factory water coolant turbo feed is blue, the red is for the 2G oil cooler coolant feed line (i think).
Green its a simple thermo valve, keep it unplugged or plugged no mathers.

Engine Pic:
Purple is the water turbo coolant feed line, you need these pipes if you use an water cooled turbo like factory : http://www.streettunedmotorsports.com/parts/b/stm_water_line_kit.jpg (feed line on top)
Yellow, use the proper oil restrictor according to the turbo used (if needed), Edit : look the post#5
White, factory water coolant return for the 2G oil cooler (edit: or 1G 91/94 DSM), plug it or run a hose from it to the red colored fitting on the TH.
Pink, factory emplacement for the oil pressure switch (idiot light)

Sorry for my American language ...

The yellow one is the unfiltered oil , the pink is for an oil pressure switch.

^^^^ Yes according to the RRE web site install guide : http://www.roadraceengineering.com/instructions/oillineinstall.htm you need to use the filtered lower port (not visible in your picture)
I edit again my first post for correction
Thanks you synthetek !

Not that it's a huge deal, but we've got our feeds and returns all mixed up here.

Thermostat housing pic:

Both of these are feeds. Do note that it technically doesn't matter which one is for which -- only that one is the feed for the turbo and one is the feed for an oil cooler. But from the factory, yes, the blue is for the turbo and the red for the '91+ oil cooler.

Again, mixed up. Purple is the turbo coolant return line and white is the '91+ oil cooler return.

OOHHH so where my Yellow line is ran right now needs to move down to the lower port! Bingo!
So in summary:

Yellow is Turbo Oil Feed (when moved to lower port)

Pink is for the dummy switch.

Purple is Turbo Water Return Line (radiator side port)
Blue is Turbo Water Feed Line (engine side port)

Green (ECT) can be capped off.

Since the 90 oil filter housing has no ports for water cooling, White will get ran to Red or just have both of em capped off.

Purple is the water turbo coolant feed line, you need these pipes if you use an water cooled turbo like factory : http://www.streettunedmotorsports.com/parts/b/stm_water_line_kit.jpg (feed line on top)

STM looks like a good kit, i'll get it if i can't find anyone that has some used parts

Thank you Synthetek and ColtiXim

Another ?? If i ran a mechanical oil pressure gauge, where would i tie it in?

Edit: Thanks to 19Eclipse90: Feed/Return line corrected

My bad, again sorry for my bad translation ...
This diagram has good information :

Depends on what else you intend to keep on the housing. If you are going to keep the original sensors for the oil pressure dummy light and the original dash pressure gauge, then use the location you originally had circled in yellow. If not, then use the port of whichever sensor you won't be using.
