V1 need guidance on Z54 plumbing

[SwerveMonkey]

heya folks... at the risk of sounding like a complete idiot... does anyone have confirmed plumbing instructions for the Z54 turbo from ZZP? Thanks in advance for the help... I've tried scouring for example plumbing images and diagrams with little to no luck

unfortunately for me, I've not a lot of experience with the turbo plumbing layout to surmise which port is what.
I've got a rough idea on what plumbing should go where, but need precise info on stuff like what size banjo bolts go into the central housing of the turbo. I gather that the bolt size should be Metric with a 1.25 thread pitch, but unable to size without guessing.

Moreover, I'd like to get confirmation as to which port is intake [both oil intake & coolant intake] and which ports are drainage.
two images attached show the ports in question... of which IDK what port is what....

my assumptions are that the ORANGE port is an oil drain, the PURPLE ports are coolant ( intake or drain )

and that the BLUE port, which has a 90* elbow fitting is the oil intake

Yep, pretty sure you're exactly right. That's what I remember mine looking like. I know the oil and water feed/drains are perpendicular to each other.

blue is certainly an -an fitting oil feed

Bump for another question if people know the answer....

Does the Watercooling only need the two ports that are shown or will i somehow benefit from having all four cooling ports utilized??
Having supply being run through two ports on one side and two ports on the other as return... not sure if neccessary though.

Also where do people find anythin akin to a user manual for Turbos?? I cannot find a reference drawing or diagram for this thing

One pair of those ports is for oil to lubricate (and cool) the bearings, the other is for water cooling - if you decide to run the radiator fluid though that circuit. Do not get these crossed up, as bearings don't like water. I suppose both sets of ports could be run with oil as well, but the high pressure oil from the engine must go into the correct port for the bearings - that will direct the oil onto the bearing face (if a journal bearing).

Usually the oil enters from a small hole at the top (blue circle) of the center housing, and leaves out the bottom (orange circle).
The 2 holes on the side are for coolant.
Here are some pics of a Saab turbo.

On a side note, make sure the supplied plugs are tight. Mine were loose and leaking coolant. Still in the cobalt when I did the swap so was hard to figure out it was leaking from the plugs, probably not so bad on the Goblin.
